N
early ninety-five years after Roy Otis Martin purchased Creston Lumber Mill in Alexandria, Louisiana for $32,000 and renamed it Roy O. Martin Lumber Company, the Martins have started up a $280 million greenfield oriented strandboard plant in Corrigan, Texas. Let that one sink in a while. Much has been written in the pages of this magazine and elsewhere through the years about the Martin family and its remarkable forest products business, which we know best as RoyOMartin or even Martco. The family itself published a book some years ago, but as demonstrated by the new Corrigan OSB plant, it’s a story that apparently has no ending. My familiarity with the company and its current chairman, Jonathan Martin, goes back to when he was focusing less on their pine sawmill in Castor, La., where he had been plant manager, and more on the startup in 1983 of their first OSB plant in Lemoyen, La. The company had started up the Castor sawmill way back in 1933, and the founder’s son, Ellis, who was Jonathan’s father, became plant manager there in his early years. Many years later Ellis led the company into OSB and Jonathan took the lead on the construction of the OSB plant. Martco’s mill at Lemoyen, GP’s OSB mill at Dudley, NC and LP’s “waferwood” mill at Corrigan, Texas were the first three in the South, all reporting production in 1983. Unique to Lemoyen however was that its raw material was hardwood, as the Martins owned considerable timberland in the area packed with low grade hardwood. The company also started up a hardwood sawmill at Lemoyen shortly after. Speaking of sawmills, as the company continued to invest heavily in OSB—starting up a second one in Oakdale, La. in early 2007 and of course the Corrigan facility this year—sawmills always had their place: Alexandria, La.; Castor, La.; Lemoyen, La.; Mexia,
Ala.—all of them since sold, but now running a timbers mill adjacent the Martin softwood plywood mill in Chopin, La. And speaking of Chopin, by the time it began production in 1996, Jonathan was president and CEO, and his cousin Roy III was executive vice president and CFO. While I had conversed with Jonathan many times, it wasn’t until 2004 when I visited the new and very impressive headquarters in Alexandria that I had the good fortune to converse with Roy. Their official titles have changed through the years, not that anybody ever had their titles straight anyway. I don’t recall ever asking them if they felt they were lumber guys or panel guys, but I’m guessing they would respond that they are simply forest products guys and point to the 550,000 acres of certified timberland the company owns. They are also very spiritual guys, philanthropical guys and employee-centric guys. At the fear of leaving somebody out, I won’t even begin to name the talented personnel they’ve always surrounded themselves with. I’ve always been very appreciative that they have continued to let our editors into their mills so we could write and publish articles such as the one that starts on page 10 of this issue. May many more chapters be forthcoming. PW

UPDATE ARAUCO-GRAYLING IS PAVING THE WAY As of the end of August, Arauco reported 1,526,355 total project hours completed since April 2017 at its particleboard plant under construction in Grayling, Mich. The company also reported the use of 802 contractors and the hiring of 175 employees. The plant is built on an 160 acre site. The main building is 820,000 SF. In addition to the particleboard production line, which will feature a 10 ft. wide by 52.5 m continuous press, the plant will operate two thermally fused laminating lines.

BIOMASS BILL WINS THE DAY Inspired by the support of loggers and timberland owners, the New Hampshire legislature overrode the governor’s veto of SB365, a bill that supports the state’s six independent biomass plants and waste-to-energy facility. “The legislature made the right call to override the veto of SB365. When you consider the vast impacts this bill has not only on various sectors of NH’s economy, but also on NH’s established and treasured values, the small cost is vastly outweighed by the benefits,” says Jasen Stock, Executive Director of the New Hampshire Timberland Owners Assn. (NHTOA). “In addition, the override successfully protects NH from the longterm $17 million annual cost our state would have to pay to replace lost generation capacity. Our state’s forestry, recreation, tourism and agricultural industries were on the line, and we thank the legislature for hearing the facts and fixing the

UPDATE
governor’s mistake.” Earlier, representatives from NHTOA, New Hampshire Sustainable Energy Assn. (NHSEA) and Granite State Hydropower Assn. (GHSA) had presented the N.H. Speaker of the House and N.H. Senate President with hundreds of petitions containing more than 6,500 signatures from more than 200 towns urging the override. The petition drive was one of the largest veto-override petition drives in New Hampshire history. “I’m feeling relieved for the men and women in the forest industry, and I was proud to stand with the men and women in forestry and fight this good fight,” says Tom Thomson, an Orford tree farmer and son of the late Gov. Mel Thomson. Thomson helped organize foresters and supporters of the bill, which will require utilities to purchase a portion of their electricity from the state’s wood-burning power plants. Supporters of the bill, including the state’s six independent chip-burning plants, warned that Governor Sununu’s
veto would make it difficult to continue operations without the assured income. In the wake of the veto, four out of six biomass companies either closed or partially closed. Sununu had argued the bill would amount to a subsidy that could cost bill payers $25 million annually over the legislation’s three-year lifespan. The bill requires electric distribution companies to offer to purchase energy output of eligible biomass power facilities as well as facilities that produce electricity using municipal solid waste as a primary energy source. The bill had stated: “The continued operation of the state’s six independent biomass-fired electric generating plants and the state’s single renewable wasteto-energy generating plant are at-risk due to (natural gas) energy pricing volatility. These plants are important to the state’s economy and jobs, and, in particular, the six biomass-fired generators are vital to the state’s sawmill and other forest products industries and em-
ployment in those industries…and are also important to state policies because they provide generating fuel diversity and environmental benefits, which protect the health and safety of the state’s citizens and the physical environment of the state.” Sununu had countered that the bill creates “another immense subsidy” for the six biomass plants. “Senate Bill 365 doesn’t even guarantee solvency of these facilities,” Sununu said. “We need to be taking steps to lower electric rates, not passing legislation that would cause massive increases.”

THE NEWEST, THE BIGGEST, CORRIGAN OSB IS HITTING ITS STRIDE RoyOMartin’s new greenfield OSB plant in Texas is a technologically advanced behemoth.
BY JESSICA JOHNSON
CORRIGAN, Tex. itting on 1,703 acres, 158 acres of dedicated plant site (13.5 acres under roof), less than 100 miles north of downtown Houston, now the third largest city in the U.S., the newest greenfield oriented strandboard plant in North America is ready to attack the hotbed of markets in its backyard. RoyOMartin’s Corrigan OSB facility has a capacity of 800MMSF, and just shy of six months after pressing its first board, RoyOMartin Vice President of OSB and Corporate Safety Director Terry Secrest says the facility is operating at 60% capacity and rising. President & CEO Roy O. Martin III says the proximity to Houston, Dallas and other markets in Texas, not to mention southern California, Phoenix, Denver and others was one of the driving forces in selecting the city of Corrigan for the plant—a project that was first dreamed up by his cousin, Chairman Jonathan E. Martin, with scribblings on a napkin. “Market projections were steady, not running too hot or too cold,” Roy says. “We saw the number of plants that were down, what we projected we thought would come back up, and those lines intersected about 2017. That’s when we thought the country would run out of board.” The Martins gave a very hard look at

Corrigan back in 2007, when they were preparing to build an 850MMSF softwood OSB facility, but ultimately they chose to build in their home state of Louisiana, at Oakdale. But they never forgot about Corrigan. Roy says it was the people who really captured his attention. A Blue Ribbon high school in Corrigan and other wood products facilities that kept the logging force very healthy created the perfect opportunity for an OSB plant. So when the time came in 2016 to begin site selection, Corrigan was it.
Roy admits, “We came back here with blinders on. We were going to build here.” Though, Secrest says, consideration was given to simply putting a second complete line in at Oakdale. The Martins like to be first. Roy has a saying, “I don’t like to be bleeding edge; I like to be cutting edge.” Which means, if you’re going to do something, do it big, and do it well. Bleeding edge runs the high risk of being unreliable. Roy doesn’t like the term pioneer; instead he calls Jonathan, himself and the company “perfectors.” In regard to Cor-

rigan, he takes it one step further saying they wanted to be first, because it was important to get ahead of the surge. In addition to the people, the east Texas timber basin got the Martins’ attention. The wood basket in the surrounding region—untouched since the Abitibi paper mill in Lufkin was shuttered in 2004—will supply the OSB plant two times over. While the Martins owned 550,000 acres in Louisiana, they owned no timberland in Texas, so seeing the unused standing timber was especially at-
tractive. Secrest adds that one of the reasons for not putting in a second complete line at Oakdale was timber competition; and having the underutilized acreage in Texas was the metaphorical icing on the cake for Corrigan.
DEVELOPMENT RoyOMartin officially selected the site in February 2015. Permittings and approvals (air, storm water, waste water, wetlands, etc.) was no small un-
dertaking, but successfully completed. Construction began in July 2015. Secrest cites some fascinating statistics: They moved 1.2 million cubic yards of dirt; poured 281 million lbs. of concrete; brought in 115 truckoads of steel; laid enough electrical cable to stretch from Corrigan, Tex. to Portland, Ore.; and installed six miles of safety handrail throughout the plant. The mill contracted with O’Neal of Greenville, SC for electrical engineering and budgeting; Johnson & Pace of Longview, Tex. for mechanical and civil engineering. Secrest, based out of Louisiana, spent a lot of time in Texas getting Corrigan through construction and commissioning to first board production. Adrian Schoonover, (recently retired) vice president of engineering, led the construction project, along with Steve Wilson director of construction, and Marty Neiswender, director of manufacturing and Corrigan startup manager. The onsite leadership group, Michelle Driscoll, production manager, and Mike Schalau, maintenance manager, was brought in fairly early in order to involve them as much as possible. Project criteria and goals were foremost on everybody’s minds from the outset: highest possible priority on the safety, health and environmental aspects; cleanliness and “employer of choice” place to work; lowest possible long-term operating cost; constructability within budget; recognizing the significant cost of undercapacity production. Production team members were also hired early, giving ample time to, as Jonathan calls it, “Martinize” them. He explains, “We all make board. We don’t have titles. You have to have the, ‘I don’t care who gets credit as long as we get this done,’ attitude. We’re all Martins.” He adds that the sense of urgency is important in the work, but most importantly it’s how everyone treats each other. RoyOMartin Co. is first and foremost a family, and every employee is required to treat each other as such. Secrest says part of Martinizing the employees is making certain the right person is hired to fit with the culture of the company—identifying who has the right leadership skills. For example, Production Manager Driscoll came up through the technical lab side of wood products. “She had made particleboard and didn’t know how to make OSB,” Secrest says, “but she was a good fit for us. We can teach people the technical skills. We can’t teach them how to fit in.” ➤ 13

CUTTING EDGE NOT BLEEDING EDGE: THE PIONEERS OF OSB IN THE SOUTH In its third generation of family leadership, RoyOMartin continues to be led by a pair of talented cousins with impressive tenures in the wood products business. EDITOR’S NOTE: Cousins Roy O. Martin III, 58, (President, CEO, CFO) and Jonathan E. Martin, 70, (Chairman) have worked in their family’s company since they were old enough to lace up a pair of boots—both have memories of sweeping floors and pulling sticks as youngsters. Though the company was founded by their grandfather as a sawmill business, and the business has operated it share of sawmills, it’s the structural panel business that has gained worldwide attention not only for the company, but for Roy and Jonathan as well. Today they spearhead two high production OSB plants and a softwood plywood mill, which complement 550,000 acres of family owned timberland. In September they sat down with associate editor Jessica Johnson at their new monster-sized softwood OSB plant in Corrigan, Tex. Panel World: You both have worked tirelessly to further the company your family started 95 years ago. And the company certainly has changed during your time. What would you say was the pivotal moment in your career? Roy O. Martin III: When I was born probably; I’ve been in the company my entire life. In all seriousness, there have been a series of them. Making the decision to come work in the company in 1982, right out of school, was one for

me. Going to MBA school was another one. The decision to build a plywood plant in 1996 was so pivotal. That was so counter industry. Plywood was dying. In 2001 we reorganized the company. Of course, Oakdale was pivotal. So was the decision to start hiring professionals—that was a huge thing for us. Getting the best talent not necessarily in the panel business, but from paper mills, and other places jumped us into another plane. A pivotal non-moment was not getting overextended; also not getting into bad businesses.
PW: You run such a strong company that is truly like a family. When did you notice that you started putting your money where your mouth was, so-tospeak, and step up for not only the employees but their families as well? JEM: We made the decision to hire chaplains 20 plus years ago. And now we’ve got members of the chaplain team in every plant every day. They are just available to visit with confidentiality for any spiritual need or home need any employee has. The chaplains are
“We’re in the forest products business, but we’re really in the people business.” —Roy O. Martin III Jonathan E. Martin: Definitely when my dad told me to go buy an OSB plant and I didn’t know what OSB was in 1981. At that time there were only five plants to go see, mostly in Canada, and then LP’s in Hayward, Wis. The second pivotal moment was hiring Roy and we went from a family run company to a professionally run company. In 2002, we adopted a family constitution and created a family council, which tells us how we will behave so we will remain a family run company for the next 95 years. The decision to build Oakdale, shut down LeMoyen and start up Oakdale was also very pivotal. That was like taking part of my heart out.
part of a national company, so they can support any employee no matter where. My sister had open-heart surgery in Michigan and they had a chaplain with me all day. It’s a wonderful service. ROM: It is such a wonderful connection. Their goal is to see every employee every week—1,280 people is a lot of people. They just make themselves available. It’s not a push. It’s non-denominational, interfaith. We can serve all employees. It says we care. The chaplains are part of a bigger initiative called Martin Cares, which includes an extensive support system on the physical health side as well. We have a Physicians Assistant that comes to Cor-

rigan every Monday, plus the medical home in Alexandria that serves all employees and their children. There is a full time nurse at every facility for first aid, occupational health and wellness coaching. During the OSHA mandated audiology exams, we have the option for employees to get their blood work done, blood pressure checked and have a quick exam.

do. I’ve worked in this business since I was 10 years old picking up sticks in a sawmill and came immediately back to work after I graduated college at Louisiana State University (LSU). That’s all I’ve ever wanted to do and that’s all I still want to do. I’m done building things. We’ve got enough to look after right now. The capacity, demand and supply are pretty well equaled out with this plant. You have got to be careful.
PW: While the panel production industry can be very competitive, there’s also a fair amount of camaraderie. How do you feel you fit in?
ROM: We’re going to take a breather. Cross-laminated timber (CLT) is a very interesting deal. My daughter is an architect in Nashville, Tenn. and my son is an engineering MBA in Baton Rouge, La.—all of the architects are extremely interested in the European method of building commercial buildings. I’m seeing a lot of economic viability with that building process. But, I don’t want to be bleeding edge; I want to be cutting edge.
JEM: I sit on the Board of Trustees of the American Plywood Assn. (APA), and years ago we started a safety council among the members, because that’s one thing that’s noncompetitive. Terry Secrest (VP of OSB) headed that up for years. We get together with other industry people in panels and OSB, talk about new ideas, and their approach. We share a lot of noncompetitive information about safety with each other. ROM: We are very, very careful that there is no anti-trust violation during APA meetings; our General Counsel Ray Brown preps us every time we go anywhere. We don’t want to have any collusion at all, but we do want to share safety secrets. That’s good for the whole industry and the whole country. PW: Combined you have 80 years of experience in forest products manufacturing. What are your current feelings about the industry? ROM: Right now, it’s a good time to be in panels. You have to have a very strong stomach and be able to look at the long-term—not have a quarterly mentality. This is a long-term business. You’re going to experience bad business. JEM: But we grow trees, so we naturally think long-term. ROM: And we will continue to grow trees. PW: It might be hard to imagine, but if you could do anything else, what would it be? Are there any plans for another monster plant in the future? JEM: There’s nothing else I want to
JEM: It’s still got to grow. A lot of CLT manufacturers are making crane mats—they aren’t putting it in buildings. ROM: Every municipality has to pass building code to accept it. And that’s a long way off. The other thing we are doing right now is modernization; we are modernizing our plants technology wise. We also are learning how to use different varieties of timber.
Culture is extremely important 11 ➤ to the leadership group, both on site and at corporate. As such, there is not a designated plant manager in Corrigan. Driscoll reports to Neiswender, and Neiswender essentially serves the role as plant manager for both Corrigan and Oakdale. Secrest says he did it this way to make sure the same culture was at both facilities. “One team, one dream— facilities work cohesively instead of competitively to accomplish our business goals,” he details. Throughout the dry running/commissioning phase—the first board was pressed on April 24, 2018—to standard production today, Secrest says he’s most proud of the team. Everyone really stepped in and stepped up. The Martins built a beautiful, world-class facility, he says, and now the production team is overcoming hurdles, making progress and getting to the point where they are operating a world-class facility.
TWO OF A KIND One of the benefits the production team had was being able to train at the Oakdale OSB facility. While it isn’t exactly a sister plant to Corrigan, it has many similarities. However, Secrest and Driscoll are quick to say that as with any startup, there are many upset conditions that have to be handled.
JEM: Changing out all the brains of your operation is a big deal! PW: What is your single biggest accomplishment? JEM: I have two fine Christian daughters and two fine Christian young men. I’m more proud of that than anything. ROM: I have a daughter and son, and same way, I am so proud of them. And he’s got grandchildren; I don’t have any grandchildren yet. JEM: We took a very good company and made it a great company. We’re much different than when I started in this business in 1971. ROM: Much different for the better! From the second to third generation, we’ve made a 1,000% improvement. Hopefully the fourth generation will take this thing and go on from here.
At capacity, Corrigan will receive 960 truckloads of wood per week.

The technological leap between Corrigan and Oakdale is significant. Secrest says sometimes it is mind blowing to think of the differences between the two plants, adding, “Though we have tremendous experience, there are still things here we’ve had to learn and adjust and correct. It’s technologically much more robust than Oakdale.” The biggest difference between Oak-

dale and Corrigan is on the technology side: the electrical and drives, motion controls on the forming line and the way that the CPUs are tremendously faster, Secrest notes. An ethernet network links the entire facility, and all the different devices talk to one another and
provide information instead of individual PLCs. “On the hardware side, not really any kind of difference. It’s really in the software and the way we make things happen and make things go,” he explains. Most equipment was selected for spare

parts commonality and the experience that 10 years in Oakdale provides. Familiarity and success in Oakdale led Corrigan to Dieffenbacher and ConVey. Some pieces were upgraded in size, such as the Kadant Carmanah ring stranders. Dryers are also a size larger. Selection of PAL wet bunkers is a departure from Oakdale. Conveyors are shorter because of the compact nature of the facility. “We know how to run Oakdale well and we know how to maintain Oakdale, so we went and selected everything we wanted to keep: screens, blenders, form-
ing line, saw line. We have a lot of commonality because we knew how to run them and maintain them. Some areas we said we wanted to improve upon,” Secrest says. Routinely, Oakdale maintenance team members will travel to Corrigan to work a down day and show Corrigan’s maintenance team things to look for. When selecting familiar equipment it gives maintenance a chance to share secrets—things that Oakdale has learned that are not always easy to put into a PM. Taking care of details made a difference here already, Driscoll notes.
Material is blended with wax and Hexion-supplied resin in Coil blenders.
For Roy, the more advanced technology has benefits and curses. Complicated software means more difficult troubleshooting, and a steeper learning curve. “It’s a challenge, but we’re learning quickly,” he says. Though not at 100%, the corporate leadership team believes the plant is running at a pleasing rate most of the time.

PEELER BLOCK PRECONDITIONING: FRESH LOOK AT AN OLD PROCESS New veneer and plywood production technologies make proper preconditioning even more essential.
BY DICK BALDWIN
reconditioning the peeler block by heating and softening the wood fiber is crucial to producing quality veneer. An abundance of factual information has been gathered over more than the past half-century and today’s green veneer producer can benefit from this ever-growing body of knowledge that, when applied properly, assures effective preconditioning. The data is
P
sourced both from applied research in the laboratory and also empirical learning at the mill site. Yet, some producers still do not recognize the need for effective preconditioning, while others recognize the need but struggle to fully obtain the benefits. A recent phone call to the author, originating from a lathe deck in the Southeastern United States, was a timely reminder that questions linger because many mill operators still are not familiar with proven best practices. For example, lingering questions include: How does the mill operator become educated on the benefits of preconditioning, and roll out best practices over time? How should the mill operator manage the preconditioning process? What are the tell-tale signs that preconditioning is being done correctly, or incorrectly? If veneer peeling efficiency is not optimal, what are corrective steps to improve the quantity and quality of green veneer production? Let’s discover, or rediscover, the answers to these and related questions.
RECOGNIZING NEED An editor on assignment for Plywood & Panel World asked similar questions in 1988 when visiting the GP plywood plant in Russellville, SC. The editor interviewed Don Foster, then group manager for the Eastern Wood Products Div. of GP, who stated:
Block conditioning at a North Carolina plywood mill
“Good, proper block conditioning is essential to get (maximum) yield out (of) the log and to get a good smooth peel.” Foster emphasized the importance of peeler block preconditioning by declaring that not doing it correctly was a pet peeve of his. Little wonder that the editor declared to his readers after visiting Russellville: “Log preparation (preconditioning) is the cornerstone of Georgia-Pacific’s plywood mills... “Put another way, GP peels no log before its time.” Thirty years later, effective preconditioning has become even more important as log and peeler core diameters continue to decline. These industry wide trends of decreasing diameters of traditional peelable logs are occurring concurrently with a growing variety of non-traditional log species and types. Moreover, contemporary peeling innovations are unlocking the potential of newer automated green veneer systems with lathe processing speeds only dreamed of just a few years ago. As a consequence, these newer green end systems have less tolerance for improperly preconditioned peeler blocks and the consequences of improper preconditioning are more severe.
KEY TO PERFORMANCE “GP peels no log before its time” was an operating cornerstone 30 years ago, and has become even more important today. Poor or moderate preconditioning can result in sizable operating inefficiencies and financial losses. The quantity of veneer recovered from properly conditioned blocks is 3 to 25% higher than cold blocks, and the quality of the veneer also is better with fewer cracks and splits (Resch and Parker, 1979). Improperly conditioned blocks adversely impact the green and dry veneer production processes. At the lathe, cold blocks cause a high frequency of breakouts and spinouts. Downstream from the lathe, more cracks and splits in the veneer ribbon cause fewer wide sheets to develop, an increase in green clipper waste, and a higher proportion of scrap veneer to go to the chipper. Downstream consequences as the veneer goes through the drying and panel production processes are equally insidious. Broken sheets occur with greater frequency when handled mechanically or manually so veneer is wasted at both the dryer infeed and outfeed. Unnecessary waste production

then continues into the panel layup stage with more sheet breakage, higher throwaways, and a greater proportion of culls and seconds. One Southern westside mill was observed routinely peeling logs “before their time” for a variety of reasons. Low productivity and yield losses of an estimated 15 to 18% were attributed to an insufficient peeler block preconditioning facility. Fortunately, operating efficiency can be improved through welldefined changes and greater attention to best practices. Another Southern producer who asked to remain anonymous confirmed the incremental value of proper preconditioning when peeling regional pine and is moving to widely implement best preconditioning practices. An assessment team evaluated data collected from multiple lathes in multiple mills over a recent two-year period (20152016). The evaluation process correlated veneer quality to two independent variables (log temperature and block diameter during peeling). This multiple mill assessment gathered data during peeling from initial peeler block rounding to peeler core dropout. A temperature sensor, mounted on the core drive unit, scanned the peeler block temperature mid-length. Block diameter was concurrently measured during the temperature sensing process. Two-hundred of the best two-hour operating periods were identified. Best was defined as the highest volume of useable veneer (M 3⁄8) developed at the lathe during the two-hour time periods. The best two-hour periods shared common attributes: ● Core temperature during the two
hours of peeling varied no more than 10 degrees Fahrenheit from block to block. It didn’t seem to matter if the average was 110, 120 or 130 degrees. What did matter was consistent temperature during peeling. ● Initial block diameters over the two hours were within one-half inch. Consistent diameter from block to block closely correlated with consistent veneer temperature. ● Veneer production volume was typically 4-5 M 3⁄8 higher during the best two-hour periods when compared to other two-hour operating periods. Varying initial block diameters apparently prompted inconsistencies in block temperature during the peeling process, in spite of consistent water temperature during the preconditioning process. This cited analysis is more an empirically derived rule of thumb than pure science. However, this mill data is a credible indicator that consistent elevated temperatures are important to obtaining the most and the best from the incoming peelable log. This multiple mill, multiple year assessment is an additional source of data to improve a long misunderstood and neglected process.
CHECKERED HISTORY Early Twentieth Century attempts to cold peel Douglas fir with a fixed nose bar resulted in persistent downtime and waste. Although the lathe operator kept a watchful eye and slowed rotation to a crawl as the lathe carriage approached a pitch ring or other defect, plugged lathe carriage heads were common. The deck man or lathe operator predictably em-
ployed pry bars to manually remove wood debris between the lathe knife and the adjacent nose bar. Besides endangering the lathe operator and deck man, inevitable outcomes of peeling cold blocks were low production, yield losses, rough veneer, and a loss of A grade veneer. Consequently, operators in the early days began to heat old-growth peeler blocks with steam or hot water as a way to minimize downtime, to obtain a smoother peel, and to improve the veneer yield from the log. However, George Osgood and Adolph Gaines of Wheeler-Osgood Company subsequently invented and patented the roller bar, a technology to cold-peel Douglas fir. This device, rotating opposite and parallel with the tip of the lathe knife, created less drag on the log. The lathe could then peel closer to ring shake or other defects with fewer and less costly plug-ups. The Osgood/Gaines innovation had unintended benefits in terms of the need to precondition Douglas fir. Preconditioning with steam or hot water was no longer considered necessary by many operators west of the Cascades. However, operators rediscovered the need to properly precondition peeler blocks once the plywood industry expanded into the Intermountain West during the post-World War II building boom. Unlike the temperate climate and heavy rainfall of the Pacific Coast, at times inland winter temperatures plunged to minus 20 to 30 degrees Fahrenheit. Plywood plant operators soon learned that preconditioning was essential. For example, the Potlatch plant in Lewiston, Idaho began operations in 1952 and Western Plywood reportedly began

even earlier in interior British Columbia. The Polson Plywood Company plant in Polson, Mont. began peeling Western larch and interior Douglas fir in 1956. Concrete block heating structures were installed at each inland mill. A steam and water mixture were then injected into the closed vault until the proper peeling temperature was reached with residence times stretching into hours; the number of hours were contingent upon the block diameter and species. For example, interior Douglas fir, colloquially called Red fir, peeled faster and had improved green veneer handling characteristics when heated to 120 degrees F from the surface to the core. What worked well in winter proved to work even better during the summer given the higher initial ambient temperature; benefits included softening hard knots, a smoother peel, and overall improved yield when compared to cold peeling during the warm summer months. Although preconditioning had demonstrated obvious advantages in the Inland West, it was still considered less important by many West Coast operators. However, attitudes began to shift during the sixties as softwood plywood manufacturing developed in the Southeastern U.S. where preconditioning the native pine species was essential to peeling useable veneer. The successful industry expansion in the Southeast did not go unnoticed by other operators in other regions. Most modern mills everywhere in North America now have some form of preconditioning with some doing it well, others not doing it so well, and others exploring ways to eliminate this step in the veneer production process. Let’s review how to do it well.
mined by the properties, including species density, cell structure, and other variables of the trees being peeled. 2. Water, and wetting, are important heat transfer mechanisms. Burrell said it best nearly a half century ago: “Water is a good conductor of heat. To start heat moving into a block, you must first get it wet. The heat, using the wet surface as a vehicle, will move into the wood and soften… the block.” (Burrell, 1972). In other words, wetter is better. Sufficient time is therefore required to apply and diffuse the heat and chemicals (if chemicals other than caustic soda are used) throughout the peeler block. A research report published by the Canada Department of Fisheries and Forestry describes some further considerations such as the effect of humidity: “…the slower rate of heating was obtained in air at low humidity, but the rate increased as the humidity of the air
increased. Increasing the humidity of the heating medium with a water spray or steam/water mixture prevents endchecking. It also speeds the heating cycle. One such process offers an example. This process mixes a steam boiling water, and alkaline chemicals to generate: an ‘explosive action creating a turbulent, homogenous atmosphere…’” (Canadian Department of Fisheries and Forestry. 1970. Heating of Veneer Blocks. Research News 13 (5)) The slightly alkaline atmosphere envelopes the block and the highly humid atmosphere results in uniform heat distribution.
BLOCK HEATING Actual block preconditioning methods cover a gamut of technologies and applications. These range from primitive, such as the application of straight steam under a make-shift canvas covering, to carefully engineered and installed drive-
Figure 1.1
HOW DOES IT WORK? Preconditioning is essentially the application of heat over enough time to uniformly heat the peeler block to a consistent temperature from the outside to the core. Often, chemicals are added to the vat water. Most additives, such as caustic soda, are used to neutralize the effect of acidic raw wood extractives on metal and concrete. Some mill operators aver that select chemicals, combined with hot water, actually assist the efficient diffusion of heat within the peeler block. There are at least two basic heat transfer truisms: 1.Wood is an insulator: Wood warms slowly. Just how slowly is deter-

in chests. However, peeler blocks are most commonly heat-conditioned via (a) the batch process of drive-in chambers (See Figure 1.1) or (b) the continuous process of feeding through hot water vats (See Figure 1.2) (Resch 1988). There are a number of other local engineered variations based on proprietary design. However, most modern mills will either use soak tanks or drive-in chests, with the latter most commonly used in North America. Drive in chests typically soak the blocks with a hot water deluge. Hot water of at least 165 degrees Fahrenheit, but often more than 190 degrees, is sprayed continuously onto the logs. Live steam is sometimes used instead of a hot water deluge. Steam transfers heat but the transfer may be uneven due to the absence of a wet surface given that a dry surface actually impedes heat transfer into the peeler block. A straight steam application also stimulates end checks in the block; these end checks will show up as veneer splits as the developing green veneer is dried. Mixed log diameters create a heat transfer problem for both drive-in chambers and hot water vats. Typically, a mill-run mix of peeler block diameters will create a condition where the smaller diameter blocks are overheated, while the larger diameters lose temperature as the peeling cylinder decreases. Wetting and heating is just more consistent and efficient when processing a narrow range of block diameters. Block sorting by diameter has always been important, and it’s becoming even more important as the industry shifts to greater automation which is yielding even higher rates of processing speeds and veneer yield expectations.
Usually, but not always, the recommended peeling temperature will vary with the average green specific gravity of the wood species. Typically, the lower the specific gravity, the lower the ideal peeling temperature. Figure 1.3 summarizes and provides recommended peeling temperature by species. This data, largely based upon test results within a range of operating conditions over the years, depicts the recommended peeling temperatures for common North American species. Also note the temperature range of acceptable results. Green specific gravity is also listed by each species. Green specific gravity, used as an indicator to initially establish a preconditioning schedule, has grown in importance as more and more nontraditional species are being utilized as green veneer sources. Spruce, both Engelmann and Sitka, are listed along with Western hemlock, White fir and the Western pines as having relatively lower green wood specific gravity as shown Figure 1-3. These lower density softwoods peel best at a consistent wood temperature of about 70-75 degrees.
There are a few exceptions that contradict this rule of thumb. For example, Western pine species process best when the peeling temperature is 90 degrees Fahrenheit in spite of a specific gravity in the low forties. Conversely, higher density softwood species such as Douglas fir, Western larch, and the Southern pines species actually peel best at temperatures of 120 degrees Fahrenheit or more. In fact, some mill operators have discovered that peeling temperatures in excess of 120 degrees Fahrenheit actually enhance the quality and productivity of modern peeling systems. However, there can be too much of a good thing. Excessively high temperatures create soft or mushy ends that increase the frequency of spinouts. Fuzzy grain, rather than smoothness, is a sure indicator that the optimum peeling temperature has been exceeded.
RESIDENCE CYCLE A relatively simple, four step process will identify both the heating and postheating dwell time needed:
CRUCIAL VARIABLES Two crucial variables (temperature and time) dominate the preconditioning process. Let’s review each: ● Two temperature variables include the temperature at which heat is applied during preconditioning, and the resulting wood temperature during peeling. Fortunately, both are readily measurable. A consistent temperature at around 185-190 degrees Fahrenheit (or just under the boiling point of water) is reasonable for preconditioning most species before peeling. Wood properties, the mill’s preconditioning facilities, and the heat source may modify this recommendation higher or lower. 24 • NOVEMBER 2018 • PanelWorld

Step One. Determine diameter classes that best describe the incoming log after debarking and bucking into peeler blocks. It follows that preconditioning is more consistent and effective with a narrow diameter range of
incoming blocks. Mills, such as the multi-mill Southern producer previously described, process incoming logs into two or more diameter sorts. Frequently the operator will sort out
the comparatively large diameters at the processor; then accumulate for preconditioning on weekends when the lathes are idle and ample preconditioning time is available. Again, the more homogenous the

diameter profile preconditioned as a batch, the more consistent the results. Step two. Next, identify the wood temperature that yield the optimum peeling conditions. Figure 1.3 is a starting point that can be adjusted to local conditions as additional experience is gained. For example, Figure 1.3 shows the target temperature of Douglas fir is 120 degrees Fahrenheit. Start with the recommended temperature, then experiment with adjustments that will improve results at your location (often by moving to the high end of the recommended range). Step Three. Initially estimate the likely heat penetration factor. This factor will be influenced by variables such as the species being peeled, the associated wood properties (such as green specific gravity), moisture content, and the site-specific variations indigenous to the growth and harvest site. Typically, assuming an inch per hour of radial penetration from the surface to the core is a good preliminary calculation for a softwood species such as Douglas fir. The actual heat penetration factor will be refined as more experience is gained during ongoing lathe operation. Douglas fir has a green specific gravity of 0.43 to 0.46. Heat penetration will often be materially slower for dryer and denser wood. Step Four. Now knowing the block diameter being preconditioned, the recommended peeling temperature, and the estimated rate of heat transfer, the operator then calculates the dwell time needed within the drive-in chest or hot water tank. 1. The net peelable cylinder to be preconditioned is identified by taking the expected initial diameter and then subtracting the peeler core diameter. 2. Next, divide the heat penetration factor into the net peelable cylinder to identify the expected dwell time within the drive-in chests or vats. For example, assume that Douglas fir is the species being preconditioned. Assume the initial diameter is 12 inches average and the peeler core diameter is 3 inches. This establishes a 9 inch peelable cylinder to be preconditioned. A heat penetration factor of 1 inch per hour will establish that a ninehour preconditioning cycle is needed. This will likely heat the block to 120 degrees Fahrenheit down to peeler core drop out.
CHECKING THE PROCESS Because wood is an insulator, it changes temperature slowly. It also heats or cools at a different rate longitudinally (length of the tree or peeler block) and radially (surface to peeler core). For example, heat diffuses into softwoods, such as Southern pines, about 2.5 times faster lengthwise along the core than radially inward from the surface. Consequently, the preconditioning residence cycle can be checked manually by measuring the temperature gradient of a recently dropped peeler core in from the ends. Careful measurement along the peeler core will determine heat transfer and the progress in obtaining the recommended peeling temperature. Then divide by a factor of 21⁄2 to identify the radial heat transfer on a specific block diameter. However, recording preconditioning results is even easier with the newer lathe technology. A pyrometer mounted on the core-driver will measure and record peeler block temperature while concurrently measuring the diameter from initial diameter to peeler core.
DWELL TIME Dwell time, subsequent to the originating drive-in chest or hot water vats, achieves two essential functions. First, it allows the peeler block ends to cool and firm up as a precautionary measure to prevent

Better peeling technologies are giving more emphasis to block conditioning efficiencies.
spinouts. Secondly, retained heat will allow further heat diffusion; the resulting moisture movement will equalize the temperature throughout the peeler block. Advocates and opponents of preconditioning peeler blocks have debated the utility of preconditioning almost since the creation of the plywood industry in the Pacific Northwest. Even now there are operators who believe that newer lathe technologies, similar to the Wheeler-Osgood experience during the early half of the 20th Century, may deemphasize the need for preconditioning. However, state-of-the-art lathe systems featuring increased automation, smaller footprints on the mill floor, and faster processing speeds are causing proper peeler block preconditioning to become even more important.

CONTROL AIR EMISSIONS CONTROL TECHNOLOGIES MEET HIGH STANDARDS SET BY CORRIGAN OSB
hallmark of the U.S. wood products industry is its longstanding commitment to environmental stewardship, encompassing both ends of the material supply line—from the forest to finished goods. This obligation is fulfilled by using raw materials from responsibly managed forests and manufacturing operations that deploy gas cleaning and air pollution abatement systems, as well as low-volatility resins. RoyOMartin (ROM) is a highly recognized leading producer of wood products—all of which are Forest Stewardship Council (FSC) certified (FSC C022036), which assures builders and consumers the raw materials have come from responsibly managed forests that provide environmental, social and economic benefits. But what about the manufacturing side? To this end, ROM is equally committed to responsibly manufacturing its finished products. A solid example of that commitment is its new OSB plant in Corrigan, Texas. Construction of the state-of-the-art facility began in the summer of 2015. Corrigan OSB LLC complements the ROM manufacturing plants in Oakdale, La. (OSB), and Chopin, La. (plywood). It was the environmental performance at Oakdale that helped set the platform for the Corrigan OSB greenfield site. The dryer air abatement system at the

B&W MEGTEC provided two wet ESPs and six RTO modules on two dryer lines at Corrigan.
Corrigan plant was engineered and manufactured by Babcock & Wilcox MEGTEC, De Pere, Wis. The system features two key components—the SonicKleen wet electrostatic precipitator (WESP) and the CleanSwitch regenerative thermal oxidizer (RTO). The press abatement system also consists of a CleanSwitch RTO system. The dryer abatement system controls the off gases from two dryer lines. Two WESPs and six RTO modules are configured to provide 100% dryer uptime in the event one of the RTO modules is taken off-line. The configuration allows the plant to realize a significant reduction in natural gas and electrical consumption. The SonicKleen WESP system is positioned upstream from the RTO. It reduces particulate matter, submicron salts, and condensed VOC emissions from the exhaust of the rotary wood dryer. A critical component of the WESP is a TurboVenturi scrubber, which evaporatively cools and saturates the process air to adiabatic saturation and scrubs the larger front-half particulate matter. To help protect the WESP and RTO, the venturi also includes a reservoir for chip/strand carryover that can occur due to bridging in the primary product recovery cyclones.
Critical to the full process is the patented de-watering capability of the SonicKleen WESP hood mist eliminator, which ensures virtually no liquid droplet carryover while requiring no routine maintenance. This is a key advantage, especially considering increasingly stringent environmental requirements, providing a level of performance that matters even where a small amount of liquid carryover can adversely affect emissions test results or downstream equipment. In the Corrigan dryer application, this minimizes contamination of the downstream MEGTEC CleanSwitch RTO heat-exchange media. In the Oakdale OSB installation this has resulted in a nearly 10-year RTO media life. The CleanSwitch RTO system destroys volatile organic compounds (VOCs), hazardous air pollutants (HAPs) and provides odor control. It combines high-temperature thermal oxidation with a proprietary regenerative ceramic heat exchanger to efficiently convert VOCs and other odor-causing organic compounds to carbon dioxide and water vapor. Each CleanSwitch module consists of two energy-recovery columns connected by a high-temperature combustion chamber. The unit is internally

lined with ceramic fiber insulation for energy efficiency. Air flow is directed through the unit by a patented single switch valve, designed so one column is in a gas-heating (inlet) mode and the other column is in a gas-cooling (outlet) mode. This unique switch valve system ensures no bypass or leakage of VOC-laden gas into the clean exhaust gas. The CleanSwitch takes its name from the B&W MEGTEC patented switch valve that keeps cleaned air totally separate from dirty process exhaust. The valve utilizes a double-air seal and is the only moving part in the unit. The simple and accessible oscillating design promotes uniform air distribution and results in a maintenancefriendly system.
MILL LAYOUT “The preliminary layout of the Corrigan site was done by RoyOMartin staff based on improvements to the Oakdale site after about nine years of operation,” comments Ed Spink, VP of technology and business development, B&W MEGTEC. “Oakdale is able to consistently produce at over-design capacity. RoyOMartin’s strategy is to constantly improve process operations and not ac-
cept the status quo.” When B&W MEGTEC was engaged to assess the current operation, and offer ideas to further improve the layout and process efficiencies at Corrigan, system engineers needed to respond to the comment by Jonathan Martin, Martin Companies LLC chairman, that “the largest cost of operation is downtime.” With that, B&W MEGTEC engineers suggested that redundancies be built into the system. Spink recalls that Martin mentioned the fact that the Oakdale WESP had never caused a shutdown, so the focus went to the RTO and identifying ways of ensuring it too would not be a bottleneck to the dryer operation. “The result was complete system redundancy, which allows the plant to reduce energy consumption while providing 100% dryer capacity if an RTO module is taken off-line,” says Rodney Schwartz, Global VP of Sales, B&W MEGTEC. “In addition, man-safe dampers on the inlet and outlet of the RTO module ensure safe access for maintenance, while the balance of the system remains on-line. The customized design of the entire system was developed to fulfill the client requirement for no downtime. “It was clear from the outset this was
ROM’s pledge to continuous process improvement touches everything daily. It applies internally for all employees and operations, from production to safety. ROM also requires the same level of commitment from its suppliers. It was from this approach the company launched its due diligence to understand the design of the CleanSwitch RTO and how B&W MEGTEC delivers on safety. According to Spink, from the beginning ROM said “they were perfectly happy with what they were running, so we had to convince them we had a better mousetrap. At the risk of sounding cliché, that was the phrase I used when we first talked about the CleanSwitch RTO and its patented switch valve.” “Fortunately, we had numerous CleanSwitch units under construction at various stages of completion,” Schwartz adds. “They were relatively close by, which made it easy for RoyOMartin officials to gain a good understanding of the advances and benefits of the CleanSwitch design.” As it turned out, the CleanSwitch RTO is the only “new” equipment to go into the Corrigan mill—that is, equipment from a new supplier that was not operating at the ROM site in Oakdale. “RoyOMartin’s approach to continuous process improvement is very much like that at B&W MEGTEC,” Schwartz says. “The culture starts at the top and branches out to touch every employee. It’s truly an ownership philosophy that fosters an ongoing commitment to be the best every day. “We welcomed the opportunity to share details about how we leverage continuous process improvement throughout B&W MEGTEC’s business. And like RoyOMartin, how safety is paramount from manufacturing to being directly reflected in the engineering design features of both the RTO and WESP.” PW B&W MEGTEC supplied this article and photos exclusively for Panel World.

CONTROL INTELLIGENCE AIR CONTROL
Dieffenbacher inline scrubber operating principle
As a general contractor for the worldwide wood-based panel industry, Dieffenbacher provides its customers with an engineered solution for improving the air climate in a production hall. This is possible with a new intelligent air control system combined with the innovative Inline Scrubber. This system can also be easily retrofitted in existing plants to comply with new and stricter regulations. The Dieffenbacher solution is based on a concept specially configured to customers’ requirements. To configure an optimal solution, in-depth analyses such as CFD simulations (computational fluid dynamics) are carried out. The concept essentially consists of two systems. 1) The intelligent air control system collects concentrated and diffuse emission sources and controls the infeed and outfeed air in the hall to improve the hall climate through systematic air flow. Heat recovery aspects are also considered. 2) The Inline Scrubber is based on formaldehyde being soluble in water. Using step-by-step absorption, the advanced scrubber removes formaldehyde in addition to particulate, gaseous or liquid substances. The scrubber is integrated into the duct to save space. It binds the substances to be absorbed through smart water injection and separates them with a centrifugal unit. Dieffenbacher is undertaking its first industrial project of this type for Swiss Krono in Germany. The project includes the emission sources of two complete MDF lines and the intelligent air control system for the entire production hall. The first expansion stage will go into operation this year. The remaining expansion stages will follow by mid-2019. This technology enables Dieffenbacher to provide customers with an overall concept for machine technology and environmental protection.

ENERGY AND EXHAUST CONTROL
USNR ADEC dryer exhaust control
The Automatic Dryer Exhaust Control (ADEC) system from USNR significantly reduces the two most critical costs in drying veneer by decreasing dryer energy consumption and lowering exhaust treatment expenses. This, and the resulting productivity gains and improved veneer quality, makes ADEC a powerful tool in optimizing veneer drying operations. ADEC technology is running in 17 North American plants on a mix of new and existing jet and longitudinal dryers. This total will jump to 21 in 2019. “We purchased a used dryer, added the ADEC system, and installed it. I couldn’t be happier with the purchase, the startup, and how it’s performing. We track the numbers closely

and have realized a significant energy savings from ADEC. If I had to do it over again on another dryer, I would.” ─ Dave Powers, Mill Manager, Coastland. Indeed, Dave did in fact do it again on a second dryer which is now being installed. “Efficiency is what we were after, and this new dryer with ADEC and Cooler Pressure Balance is a lot more efficient. We’ve already achieved 95% of our target production through the new dryer, and as a result we expect to increase production capacity by 10%.”—Manjit Sihota, Richmond Plywood “We were very pleased with dryers 4 and 5 which we bought from Coe. We had seen the results of increased efficiency especially on the thermal side from ADEC, and the quality of veneer, so we wanted to stay with the same manufacturer. We’ve been very, very pleased with this machine. We reached the dryer’s capacity within a week of startup with almost no issues, which is unheard of.” ─ Jonathan Martin, Chairman and CEO, MARTCO, Chopin, La. “This dryer has some amazing features in terms of the amount of heat capacity, and how the ADEC system works. The benefits are simple: better drying efficiency, better veneer quality. Just as importantly, the way the system works we are able to run this dryer in compliance with very tight particulate emissions levels without having a pollution control device on the dryer.” ─ Doug Webb, General Manager, Thompson River Veneer Products.

CONTROL THAILAND’S GREEN RIVER P’BOARD PLANT STARTS UP SCHEUCH WET ESP en a.m., Hat Yai, 30° Celsius in the shade. The sun in Southern Thailand shows mercy and hides behind a thick layer of cloud. Regardless, Gerhard Gehmaier, Sitthichai Jamchumrus and Dietmar Kraft are covered in sweat thanks to the infamous humidity of the Thai summer months. The Scheuch experts are in the course of checking and optimizing the brand new “seka” in the Green River particleboard mill—Southeast Asia’s first “legit” exhaust gas cleaning system for the wood based panel industry. Some loose screws need to be tightened here and there, the one or other issue has to be clarified but otherwise the new Scheuch seka is doing exactly what it is supposed to do: It almost completely filters particulate matter and aerosols from the air; the white steam plume is almost invisible. This, probably a bit sinister looking steam plume, is the main reason why the Taiwanese company Green River decided to buy a Scheuch WESP (wet electrostatic precipitator). “In Thailand the local residents see this white steam plume and it scares them. They think it’s full of toxic exhaust gases. And even though we tell them that it consists of simple and harmless water vapor, they don’t believe it,” Dr. Kitti terana-sthiarphan, Assistant to Group CEO, explains. “Dr. Kitti,” as he is known among his peers, by now knows the seka inside out. Ever since the negotiations with Scheuch started two years ago, he invested an ex-

tensive amount of time to get to know the technology. And while the idea behind the system sounded logical and plausible Dr. Kitti admits he was a bit “suspicious” whether or not the wet electrostatic precipitator would keep its promise. “When we pressed the starting button and commissioned the filter in April for the very first time and it was obvious that there really were no emissions visible—that was one of the most beautiful moments of my working career,” Dr. Kitti says with a smile on his face. Andreas Koeck, managing director of
Scheuch Asia, was also extremely satisfied. “The installation of the seka at Green River was a milestone for the wood based panel industry in Southeast Asia,” Koech says. He adds: “Green River consciously accepted additional costs to invest in the latest environmental technology available. What’s more, the legislator doesn’t even call for it! An increasing number of people here in Southeast Asia insist on the right to breathe clean air and in terms of environmental protection Green River clearly sets new

CONTROL standards in the region.” In light of the praise David T.S. Huang cannot hide a proud smile. “We are pretty brave, right?” the Group Chief Executive Officer of the Green River Holding Co. Ltd. jokes. And if he is really honest, “Mr. David” confesses, he has been dreaming of a “clean” production for a long time. “Some years ago we tried to seriously reduce the emissions of our plant on our own but failed. And that was the moment when we contacted the Scheuch office.” And the rest, as they say, is history.
PROJECT DEVELOPMENT Negotiations between Green River and Scheuch were tough but fair, the devil was in the details. “We had to find a proper wording for the contract, a wording that was accepted by both parties involved. That was sometimes quite challenging due to the different cultural backgrounds,” explains Dr. Kitti. So, what are the main reasons why
Green River decided to buy the Scheuch WESP? Dr. Kitti comments: “First of all, the technology convinced us, second, there is a local Scheuch office in Bangkok and third, Scheuch really wanted this job.” “True,” admits Koeck and he especially praises the support he received from headquarters in Upper Austria. “The installation was a huge challenge because we assembled the seka with this new design for the first time and all stainless steel components were locally produced here in Thailand. In addition also the way we approached the double de-pluming— via heat extraction from dryer exhaust gasses and process water—was a unique novelty. I am absolutely delighted that the whole team collaborated in a highly professional manner.”
MORE BUSINESS It was particularly important for Koeck to be a reliable partner for Green River as the company is cur-
rently building a third plant in Thailand—and we are not talking about some random, everyday project. The plant that is situated 50 km north of the city Trang will be the longest particleboard line in Southeast Asia. Karakolidis Konstantinos, short “Kosta,” is responsible for this “Cosmos” project. His site trailer is full of blueprints and calculations. That Scheuch will be a part of this new project is already set: pneumatics and wet press suction (sap) will be provided by Scheuch; if a second seka will be part of the deal remains to be seen. How good are the chances? Project manager Kosta smiles and hints: “As far as I am concerned our seka here in Hat Yai is a very strong sales argument and a second seka simply ties in with the philosophy of Green River.” So there is a good chance that Scheuch’s first seka in Southeast Asia will be joined PW by a second one.

8 ➤ taining composite plant materials. The Lacey Act is a law intended to combat trafficking in “illegal” plants, in part by requiring an import declaration to import certain plants and plant products. Currently, “composite plant materials” is defined under the Lacey Act to include MDF and particleboard, but CPA in its comments called for an expansion of the definition to include hardboard. CPA also commented in support of a proposed approach to a de minimis exemption from the Lacey Act declaration requirement for composite plant materials based on documenting the average percent composite plant content, measured on the basis of either weight or volume. This approach would acknowledge the significant challenge associated with determining with certainty the species mix of wood chips, shavings, sawdust and post-consumer recycled wood fiber that is contained in each particleboard, MDF and hardboard panel
STERLING ANNOUNCES NEW CLT FACILITY Sterling Lumber Co., a producer of wood mats, pallets, skids, and lagging lumber, will build a new cross-laminated timber (CLT) facility in Lufkin, Texas, specifically for its TerraLam CLT mat product.

IBIZ A crucial part of construction for the leadership team was the six miles of safety handrails throughout the plant. Safety is a number one, top goal for RoyOMartin’s entire staff. IBIZ, I Believe In Zero, takes safety from a buzzword to a culture. It started three and a half years ago, first as a concentrated campaign that every single accident is preventable. “Because if you don’t believe it is preventable, you’ll never get there,” Secrest says. Since Corrigan was a greenfield project, Secrest and his team were able to implement IBIZ nearly immediately. He says that since they started counting days for the mill team in January, through upset conditions and hazards with the startup, there have been no loss
time or recordable accidents. And while Secrest is proud they have been accident-free at the plant, he’s quick to point out that IBIZ goes further than that and knows they must eliminate all accidents. “The only difference between a first aid case and a recordable is luck,” he quips. “And the only difference in what we call them is because of what OSHA tells us. We don’t want anyone hurt at all.” The next platform will be how to eliminate hazards before they cause an accident. Secrest states, “We are geniuses after the accident happens as we figure out why the accident happened and quickly put corrective actions in place to stop it from happening again. The real challenge is how we become geniuses before the accident happens by eliminating hazards.” RoyOMartin’s communications team took IBIZ and personalized it. Team members brought their families into the plant. Children, in full PPE, took pictures in their parent’s work area. Banners and posters are scattered throughout the plant with these images and a simple message: “Work safe today Dad.” PW

process heating system comprising a thermal oil heater with three flue gas passages and integrated kiln off-gas incineration as well as a steam generator. The heaters/oxidizers are mostly fired with locally available fuels such as natural gas and fuel oils. Included in CAW’s scope are all thermal fluid circulation pumps for primary as well as consumer oil circuits.
THERMAL MOD Thermal modification of wood is an environmentally friendly and pure thermal process: The woody materials are modified by using solely process heat and saturated steam; no toxic or other chemicals are used nor needed. The wood extractives driven off the lumber during the modification process are captured, incinerated and turned into a vital part of the required process heat. The required heat energy can also be generated in a “green” way by utilizing the mill’s wood waste and residuals. The total energy consumption is approximately 20-30% higher than in the standard wood drying process. Thermally modified wood products are recyclable in the same way as natural unmodified wood; also, the use of thermally modified wood products does not accelerate the greenhouse effect. At the end of its service life the disposal of modified wood will free no more carbon dioxide than the wood has extracted from the ambient air during its growth. Environmental balance is consequently ensured during the entire life cycle of

thermally modified wood products. With one of their recent jobs, Jartek and CAW took a further significant step toward a total green and CO2-neutral ThermoWood production. During a mill modernization project, one long-term client with a broad wood products operation decided to decommission its natural gas-fired thermal oil heater/oxidizer and to replace this with a system that will no longer generate emissions from the combustion of fossil fuels. This client operates a wood waste-fired power station and generates all its required energy by utilizing its mill waste. Jartek awarded CAW with the job to
design and install the first of its kind pure electric incinerator for the thermal oxidization of the kiln exhaust. This pioneering system, featuring electric flameless “flox” combustion, does not consume any fossil fuels but operates solely on “green accredited” electricity generated by renewable energy. The installation and commissioning of the system went flawless and the system has been up and running for almost two years now.

PROJECTS BEESKOW 50 WILL BUILD P’BOARD LINE
The Portuguese-Chilean joint venture Sonae Arauco has made a belated gift to its Beeskow site for its 50th anniversary. Under the project name “Beeskow 50+”—the plus stands for the future of the site 100 km southeast of Berlin—a state-of-the-art particleboard plant from Dieffenbacher will be built beginning in March 2019. The scope of delivery includes a 3head forming station, the forming line and a 42 m long CPS+ continuous press with an emissions control system. In addition, Dieffenbacher is supplying the raw board handling and storage systems, sanding line, strapping and extraction systems, and is responsible for the electrical control, transport and assembly supervision. “With the solutions from Dieffenbacher, especially in the area of the forming station and press, we will achieve excellent board properties and be able to offer our customers the highest-quality particleboard ‘Made in Germany,’” comments
Fernando Oliveira, Group Technology Director at Sonae Arauco. The new project continues a long relationship between the companies. “Our 22-year-old MDF line with the Dieffenbacher CPS still produces reliably and with the best quality, so we look forward to the new project,” he adds. Particleboard production started in Beeskow on June 9, 1966. At that time, the plant was a national enterprise of the GDR with a capacity of 30,000 m³ per year. The new particleboard plant, due to start up in October 2019, is designed to produce 600,000 m³ or more particleboard per year based on the product portfolio.
UNIBOARD CONTINUES VAL-D’OR UPGRADE Following the successful completion of a $53 million investment in Val-d’Or (Quebec) in 2017, Uniboard is investing an additional $38.5 million for its Vald’Or facility in another phase of a major upgrade project to build a world-class
particleboard and thermally fused laminate (TFL) facility. This new round of modernization will focus on screening, sifting, milling and intermediary storage equipment, which will lay the foundation for the following phases of upgrading the Val-d’Or press and finishing lines.
VANACHAI ORDERS OSB DRYER OSB production is gaining momentum in Southeast Asia. Confirming this trend is the first continuous OSB plant in Thailand, being constructed for the Vanachai Group, one of the leading Asian particleboard and MDF manufacturers. As part of the plant, Vanachai has ordered from Dieffenbacher a 32 m long, 6 m diameter drum dryer, a wet strand bin and automation of the front-end from the debarker to the strander. In the past five years, Dieffenbacher has sold nearly 30 drum dryers worldwide. With three particleboard and two OSB dryers, Southeast Asia accounts for five of these orders.

designs, manufactures and distributes industrial machinery for several industrial sectors including forest products, oil, gas, mining, material handling, construction and is celebrating its 100th anniversary. Dan Reader, President of Murray Latta, states, “Murray Latta has been a licensed manufacturer and distributor of Kimwood products in Canada for more
than 30 years. Our long working relationship with Kimwood, familiarity with Kimwood’s products, reputation and brand, as well as our respect for the employees of Kimwood made this an easy decision. Our goal is to keep operations in Oregon and invest in reinvigorating the Kimwood brand and products. ” Kris Woodard, President of Kimwood Corp., adds, “Kimwood has been in business in Cottage Grove for more than 70 years. As a family owned business in a smaller community it was important that we choose wisely who might acquire the Kimwood operations—a buyer who would respect the community, Kimwood’s long history and, foremost, Kimwood employees. The combination of the Kimwood operations with Murray Latta simply gives the operations a broader international reach and opportunities for the Kimwood employees. This transaction ensures the continued presence of Kimwood manufacturing operations in Cottage Grove for many years to come.” The new company will be operating under the name Kimwood Machinery Inc. All Kimwood employees will be retained, including Woodard, who will continue to manage the new company’s operations.

CLIPPINGS LP CONTRIBUTES FUNDS FOR FLORENCE
Louisiana-Pacific Corp. announced a commitment of $250,000 to support Hurricane Florence disaster relief efforts in North Carolina. LP will contribute $125,000 to the American Red Cross and $125,000 to North Carolina Community Foundation Disaster Relief Fund. In addi-
tion, LP will match employee contributions to hurricane relief. LP is also working with appropriate organizations to donate LP building products for rebuilding efforts in areas affected by Hurricane Florence. LP employs 700 at its three North Carolina mills, including 149 at its engineered wood products plant in Wilmington, NC, near where the hurricane
made landfall. Besides matching employee donations, LP sponsors the LP Cares Fund through the Community Foundation of Middle Tennessee to aid LP employees in the U.S. and Canada affected by natural disasters or other emergencies. Due to Hurricane Florence, LP’s Wilmington operators were temporarily shut down. “Our thoughts and prayers are with those impacted by this storm, especially our employees,” LP CEO Brad Southern says. “We are thankful that as far as we know, none of our employees have been injured during the storm and subsequent flooding over the past few days, however many have damaged homes and some have been displaced by the flooding.” The Wilmington mill suffered damage in the storm. LP inventory at the mill was not damaged. LP’s operations in Roaring River and Roxboro, NC were not impacted by the storm.
ROSEBURG CRAFTS SEVEN EPD’S Roseburg Forest Products recently published its first verified Environmental Product Declarations, providing standardized and objective information about the lifecycle environmental impact of many of the company’s wood products. Environmental Product Declarations (EPDs) provide consumers with transparent, product-specific environmental information that has been independently validated. EPDs help purchasers better understand a product’s sustainable qualities and make more informed choices. “Roseburg has begun using EPDs to better measure our environmental impact and to meet the demand from builders for ecologically responsible products,” Roseburg President and CEO Grady Mulbery says. “Wood products are durable, natural and renewable, and come from sustainably managed forests that capture carbon, making them among the most responsible building materials available today.” The EPDs cover the cradle-to-gate impacts (raw material acquisition and manufacturing) for softwood plywood, particleboard, softwood lumber, I-Joist, laminated veneer lumber (LVL), hardwood plywood and thermally fused laminate (TFL) panels produced at Roseburg manufacturing operations. 54 • NOVEMBER 2018 • PanelWorld
