These “burning issues“ have not become the focus of research and development activities at Komptech for nothing – they are major objectives as regards energy and climate policies in the future. The EU roadmap for renewable energies has become a proposal for a European Parliament and Council directive for the use of energy from renewable energy sources, and individual member states must announce their national plans of action for its implementation by 31 March 2010. The objectives (see the following table of the most important member states) are very ambitious and will, as we know, represent a major challenge - especially as energy requirements within Europe continue to grow.

For us (you as our customers and us as technology manufacturer), it is essentially the large biomass percentage, which must make up approx. 30% of renewable energies by 2020, that represents a challenge. Critics doubt whether existing resources will sufficient to be able to anywhere near cover demand. These voices come mainly from the paper and pulp industry who justifiably fear a price hike of their raw material, pulpwood, as a result of competition from, fuel wood.

In order to at least defuse this conflict, efforts will be necessary to offer quality from the fuel wood which up to now has been left behind in the forest - mostly so-called “forest residue“, comprising of branches, tree-tops, felled wood and mainly root wood, making up about 35% of the total volume of the tree mass.

The waste solution

With its processing technology, Komptech is now able to offer the capability of generating the highest quality fuel from this cheap forest waste.

Overall national objectives

Even if this refuse-derived fuel from waste high in calorific value is not a renewable energy source, it is still a valuable resource that, when utilised to the full, can make a significant contribution in the preservation of primary fossil energy sources.

Regrettably, the framework conditions currently existing both at the EU level and with individual member states are not yet adequate to force this issue much more strongly (most EU countries still lack a rule on the treatment of waste, and appropriate taxation incentives).

The fact that a considerable proportion of these valuable resources is still being either buried or burnt in conventional waste incineration plants with minimal energy return must unfortunately be described as scandalous. Given the sharp rise in oil pricing, we will have to ask the question: How much longer we can afford to be doing it?

On this note, I trust you enjoy reading this edition.

Solutions for woodland residues

After the storm Kyrill, Paula, Emma – names that will be remembered in forestry.

These are names of severe storms that have devastated vast regions of Europe over the past two years.

Great expanses are still waiting to be cleared - in many cases, total clearance is the only option for reforestation.

After removal of usable wood trunks, an unwieldy, inhomogeneous mixture of rootstocks, branches and tree-tops, intermingled with soil and stones, is left behind. A usable fuel can be generated from this provided the right machine technology is used. The perfect solution from our standpoint is shredding with the CRAMBO and screening with MULTISTAR star screens. This work is usually performed at an intermediate storage area near the clearance site, where the mobile machines are positioned and containers for the transportation of the products off-site are provided - and work can commence.

First shred Hardly any other machine has a feeding area as large as that on the CRAMBO.

Everything that fits into the hopper, 3 metres in length and 2 metres wide, is shredded. The highly mobilisable tooth power (using the hydraulic drive), the intense motion of the material and the insensitivity to embedded stones by virtue of the slow-turning tools make the CRAMBO unique for this application. With its many cutting edges, the bio-cutter used breaks up the material within a very short time to the particle size specified by the screen baskets.

Then screen Komptech star screen technology is the best route to defined fuel. A fine fraction, a medium fraction and a coarse fraction are produced in one screen operation. The medium fraction generally represents the usable fuel fraction.

The rotating stars knock any adhesions off the screen material as it passes through the screen segment. The material yields a high-quality usable fraction, since soil, sand and stones are separated off as fine fraction. A setting of 15-80 mm for the medium fraction has proven to be practicable. In order words, everything

smaller than 15 mm lands in the fine fraction and often remains on site. The coarse fraction is made up of overlengths which are again fed to the CRAMBO. In practise, screen baskets with mesh widths of 150-180 mm yield an ideal ratio of degree of shredding and throughput in relation to usable fraction.

Biomass fuel In terms of particle size, the fuel produced conforms to wood chipping category G100 (as per Ă–NORM M7133) and can easily be used in biomass heat (and power) plants with appropriate conveyor systems and grate firing.

Crambo Forest option The CRAMBO Forest version is recommended if only the fine fraction is to be separated off. It consists of a semi-trailer chassis with a swivellable CRAMBO, including crane and integrated fine fraction separation.

Our customers

Green energy from Belgium Once thing is obvious from watching Henri Elen pick up a mature compost, rub it between his fingers, smell it and then nod with an air of satisfaction - this is a quality product. This is because the person thus passing judgement has many years experience in assessing substrate for horticulture.

Henri Elen gained his experience building a large company in the substrate and soil production business. Working successfully over the course of the years, he grew the company to several hundred people and locations were set up in several countries, something which of course entailed considerable management responsibility - and, at the same time, increased distance from the exciting biological-chemical-physical process that turns raw materials into products.

Sustainable management When the hankering to return to the “roots“ became too compelling, Elen sold his business, keeping just one site to realise his ideas, or more accurately, his philosophy.

4

Elen is convinced that “it is important I have the feeling of working sustainably.”

“We at Renovius are quite consciously trying to contribute to a world worth living in for generations to come, and part and parcel of that is now the careful management of natural resources.”

Green ideas - green machines Under the company name Renovius, Elen began to realise his “green” ideas in Overpelt, Belgium, with green machines from Komptech – great importance is attached to quality even for machinery.

What started at the beginning of 2007, with the composting of green waste, developed within a short space of time into a company best described using the expression “resource recycler.”

“The generation of a renewable fuel from woody biomass is of course an issue for us as well, and this is a large growth market for us,” says Elen, “and we have aligned our machines accordingly.”

The Belgian biomass pioneer is no mystery-monger – he willingly provides information on which process steps run in the system. Clear from the outset is

that a cunning marketing strategy exists for every material stream.

Municipal green waste and green waste from gardening and landscape conservation is pre-sorted after delivery.

The woody fractions are separated off and hacked, together with untreated waste wood and residual wood. The fine fractions are screened off with a MUSTANG S drum screen and are used for composting. Overlengths are wood chips sold as bio-fuel.

The remaining green waste undergoes coarse shredding using a CRAMBO 6000 with a 250 mm screen basket.

“We can shred just about anything and the wheels ensure good accessibility.

This is important to us because we do a lot of sub-contract work.”

A screening process follows brief drying on windrows. This time with a MULTISTAR L3, a star screen machine.

Three fractions result - the fine fraction, from 0-12 mm, is used as mineral compost in garden landscaping, medium particles, from 12-60 mm, are composted and oversized particles >60 mm are destined for biomass fuel.

Elen is convinced there is no better machine for this job – nothing else needs to be added.

The next Komptech machine is used in composting. A TOPTURN X60 with lateral displacement ensures optimal blending. Watering and further displacement of the windrows is performed if required. An accurate log is made of everything happening in the windrows. From this, the right time for a turn process is determined. There is a short answer to the question “Why a TOPTURN?”: “I wanted a machine with wheels.”

After about three months, the compost is taken from the rotting surface and screened off. The MUSTANG S is used again here, this time in conjunction with a HURRIKAN S wind sifter.

A particle size of 0-12 mm is used for screening. The required maturity is reached in storage. Extensive quality checks are also made. “I am now a supplier of raw materials to my former company so I can only deliver the best,” grins Elen who, on the other side of the fence, used to be very demanding of his suppliers.

Wind sifting ensures that oversized particles are free of spurious light material.

Wind sifter and screen machine are a perfect match as regards throughput with no bottlenecks to be seen.

The performance increase of the S-version has been achieved by enlarging the suction section - realised technically by a second extractor fan in series.

Another marketable product is made from the oversized particles. This material is post-shredded at high speed and then sold on the market as wood compost.

To ensure there is never a dull moment, Renovius also runs a 28 hectare palm plantation in Vietnam. The coco fibres around the nut are processed and shipped to Europe. They are a soughtafter product here for both gardening enthusiasts and for professional horticulture.

We at Komptech are proud of these kinds of customers who shape the market with their ideas and our technology. Renovius can rely on the fact that things never stand still - because in PON Equipment, our customer has access to a professional service partner.

NEW: CHIPPO 500

At work with the CHIPPO We do not claim that the new CHIPPO 500 is a joy to work with. But it is not far off – because there is probably no tractor-driven hacker for which work is faster, easier, better and at the same time, more economical.

The tractor-pulled CHIPPO 500 is the first in a new generation of mobile hack machines from Komptech and the very first one designed for drive power up to 500 HP (370 kW). Anyone seeing the machine in action can see that this power is also converted into throughput.

Off we go Inside, a sip of coffee, a song on the radio and a relaxed driver. Outside, a gripper, a huge mountain of branches and shrubbery, and a hungry hacker.

Inside, the comfort rotating cab of a Claas Xerion in this case - with 380 HP certainly an ideal drive machine for the CHIPPO. Outside is the harsh everyday task – a new load of shrubbery is placed onto the 2.4 m long feed table before being grabbed instantly by the aggressive feed system. Whilst the driver grabs new material using the gripper, two horizontal and two vertical rollers, together with the steel element belt, reliably transport the pre-compressed material to the rotor. A loaddependent controller regulates the feed proportional to the drum speed and minimises stop and start phases. The shrubbery (also branch and tree-top material) is pulled in continuously – a drop in rotation speed is not noticeable.

On the rotor itself, twelve rigid knives with adjustable advance ensure a precision cut process.

6

Renewable energy Overlengths are kept back by the surrounding screen basket. The basket can be exchanged without the use of tools and can be extended out during operation if there is a risk of blockage. The high rotation speed of the drum (560 rpm) of course ensures high throughput – a fill volume of 120 cubic metres per hour is quite possible. Generously proportioned screws feed the wood chippings into the ejection tube. The ejection distance can be tailored exactly to requirements using an (optional) mechanical variator.

One machine – two concepts Wood trunks are on the agenda after shrubbery.

The press of a button switches to conveyor belt discharge, making more power available to the hacking process. At the same time, the drum rotation speed is set to 400 rpm, maximising shredding power – even spruce trunks 75 cm in diameter are hacked cleanly.

The entire hacking process is geared towards the production of high-quality wood chippings that conform to the norm. A prerequisite here is sharp tools – and they always stay sharp on the CHIPPO. Using the fully-automatic blade sharpening mechanism, blunt blades can be re-sharpened whilst still in the machine. The machine is ready for use again immediately – breaks in production are kept to a minimum. The gentle discharge using the conveyor belt ensures product quality is not impaired.

Quality wood chippings multiplied by high throughput divided by low maintenance costs and costs due to wear – the result is high operating efficiency, and the CHIPPO works to this calculation. This is what we are looking to convince our customers of – and we hope you will come and visit us on our demonstration tour.

MULTISTAR M3 / M2

NEW: MULTISTAR M2

New in the medium class The M-class expands our range of mobile star screens. With this, powerful star screens are now also available in the medium performance category.

MULTISTAR M3 We have designed the Multistar M3 around the operator. The machine has been ideally designed for operation with a wheel-loader. The M3 handles everything a wheel-loader can move, i.e. filling of the machine and transportation of the screen fractions.

Apropos filling - the hopper, familiar from Komptech drum screen technology, boasts a volume exceeding 5m3 and a loading height of only 2800 mm.

A loading width of 4000 mm makes filling easy, even with a large scoop width.

But star screen technology lies at the heart of the machine. A coarse screen and a fine screen underneath it split the material into three fractions – always with the perfect degree of selectivity thanks to the CLEANSTAR cleaning system. Material is discharged only at the rear of the machine, via the three conveyor belts. This way the pulling

8

mechanism remains accessible whilst working. Windrows can be installed in addition.

New: MULTISTAR M2 There is now a new machine, the MULTISTAR M2, for all those who only require two fractions but still want to leverage the benefits of star screen technology. The feed area is the same as on the M3. Only one screen deck follows, either fine or coarse screening.

With a screening area of 5.2 m2, machine throughputs match those of drum screens with a screening area more than six times the size. With 15 kW of suction capacity, the (optional) powerful wind sifter provides effective separation of contraries in the coarse particles.

As with all Komptech star screens, the drive on the M2 and M3 is electric, meaning a high level of efficiency, low noise emissions and user-friendly control.

Power is supplied from a generator or, for the lowest energy costs, directly from the mains.

Solid recovered fuel high calorific

Solid recovered fuels Refuse derived fuels continue to be hot subject for us. A processing line for commercial waste is now available in which Komptech products are used for all of the major process stages.

Using a selective treatment process, fractions high in calorific value are separated off from commercial and industrial waste, creating a marketable product. Potential customers are recycling plants for medium and highly calorific fractions (cement works, power stations, etc.) and disposal plants for the low calorific, biological and inert fractions (waste incineration, MBT or landfill).

The above diagram shows the process configuration.

Key components The TERMINATOR pre-shredder, which reliably shreds the material down to the desired particle size, is an integrative component of such a plant.

The highest degree of opening is achieved using the XF shredding unit. The UF unit is resistance to contaminants and is used when a coarser size is required.

After Fe-separation (optional Non-Iron) the material flow is diverted into four fractions by the ballistic separator:

flat, rolling and as two screen fractions, with holes of 0-30 and 30-80 mm for example.

Usually the smaler screen fraction is biologically stabilized in a mechanicalbiological-treatment plant.

The coarse screen fraction has a calorific value of 12-18 MJ/kg and enables a saving of fossile fuels when used in fluidized bed incineration plants.

Potential recyclables, or fractions high in calorific value, can be separated off from the rolling fraction for postshredding using inductive and optical sorting systems. The remaining fraction is again fed to the shredder. Fe separation is a sensible option for all fractions.

The flat fraction is made up primarily of foil and packaging fractions and is the input material for the last prozessing step - post-shredding with the RASOR. The machine generates both an injectable fraction (<35 mm) and a particle size, known as fluidized bed fraction.

All these system technology components are available in the most sensible performance range, to allow perfect tailoring to the capacity of the overall system.

TERMINATOR XF

Secure clamping We thought long and hard about the perfect tooth attachment for the XF shredding unit. Nature ultimately provided the answer - at places where the force of the bite is powerful, the tooth holder is well protected and at the same time firmly anchored in the jaw. If a tooth breaks away, the holder is not affected â&#x20AC;&#x201C; and a new tooth even grows out in many cases.

We have not come quite that far with the TERMINATOR XF, but we have found the perfect mounting.

The shredding teeth are inserted with positive-locking into recesses in the drum cladding. The tooth holder itself is seated in the interior of the drum pipe and is thus well protected. Damage to the holder is impossible, even if a tooth is used far beyond its intended service life.

The tooth is fixed securely in the holder with a screw. Basic hand tools are all that is required to exchange a tooth.

The worn tooth is removed and a new one inserted without negatively impacting the tooth attachment - the original configuration is restored.

10

This minimizes machine downtimes resulting from wear.

The tooth in refurbished for reuse in a workshop. The original Komptech welded-on tip represents an extremely cost-effective solution: Cut off the worn area with a jig, weld on the new tooth tip - done. This way every tooth can be used repeatedly.

Application commercial waste On the XF, particle >100 mm are reduced considerably when compared to the F-version, and parts >400 mm are virtually ruled out completely.

Technically, this benefit was by reducing the gap between drum tooth and opposing tooth. Raised wear rings between the tooth spirals prevent material from being pulled through unshredded.

The special contour of the drum tooth, with a long tip approx. 20 mm in length, simplifies penetration of the shredded material and provides better feeding.

TERMINATOR

TERMINATOR Direct drive A new electro-mechanical drive concept is available for the TERMINATOR, designed specifically for use in waste splitting and treatment plants.

In this case, input material and throughput are specified and all of the components are aligned to them. This results in a clear-cut function for the initial process stage of pre-shredding, which can be accomplished perfectly by an electromechanical drive.

Function Technically, the requirement was for a simple, rugged system meeting the high demands of a waste shredder: Power is transferred to a reverse gear/manual transmission unit, and then on to the drum drive, by a standard asynchronous motor using a Powerband belt system. With this combination the drive is just as reliable as a hydraulic system. If a contaminant causes a blockage, a reverse cycle is initiated (as with the hydraulic drive).

The drum reverses, frees itself and continues to turn in the shredding direction.

Even a high number of blockages within a short space of time does not cause thermal or mechanical damage.

The drive has two gears: Gear 1 with high speed for easily shreddable material such as residual waste, and gear 2 with a low speed but higher tooth power, such as for bulky waste.

Lower operating costs The electro-mechanical direct drive mechanism leads to a reduction in specific operating costs (cost per ton of shredded material). Since there are no hydraulic components, no costs are incurred by servicing or consumables such as hydraulic oils.

Of particular significance is the reduction in specific energy costs attained as a result of the high efficiency level of the mechanical system.

Plug and work System integration of a TERMINATOR with direct drive follows the principal of plug and play: Set up, connect, power on â&#x20AC;&#x201C; work can now begin.

Short installation times are possible if conveyor belt connection and electrical connection are provided. The machine is hence an interesting retrofit solution, especially as the compact size helps during installation.

The right machine exists for any system size because all installation sizes are available as electro-mechanical and electro-hydraulic versions.

The best is saved for last: In terms of investment, a machine with direct drive is the most cost-effective route to a real TERMINATOR.

BRINI separation technology

Ballistic separation Range of applications • household waste, residual waste, compost • bulky waste, commercial waste • potentially recyclable mixtures • paper and cardboard waste

BRINI separators are used to separate out the usable fractions and potential recyclables from waste.

The separator works according to the ballistic principle, and separates the feed material according to its physical properties.

Using an optional material distributor, the material mixture in the feed area falls onto rigid screen elements which are arranged lengthwise and slope upwards. The elements are mounted onto a crankshaft at each end, and the elements oscillate during rotation.

The two-dimensional fraction comprises of smooth, flat, slender fragments which are cleansed of contaminants by the shaking and rotation as they are transported upwards by the screen elements.

The three-dimensional fraction consists rigid, hard/heavy and cubic fragments which are not separated off by the screen holes selected.

The movement causes this fraction to roll and drops it downwards, and the ascending material flow is separated into oversized and undersized fractions according to the selected screen holes.

With a choice of five sizes together with integrated design options, the BRINI separator can be configured to suit the individual application.

Advantages • wide range of applications • high degree of selectivity with adjustment of separation angle • proven, efficient drive design with low power requirements • rugged design with long service life and low operating costs

12

Product characteristics Selectivity The rigid screen elements are arranged lengthwise, and facilitate excellent turning of the material and hence a high degree of sorting. The separation threshold between the light and heavy fraction can be tailored to the material.

Sturdy design The steel screen elements, with abrasion protection in the loading zone and at the side walls for extra wear protection, allow sharp and heavy materials to be handled easily.

The sturdy drive mechanism comprises of an electronic motor, gearbox and robust, maintenance-friendly crankshafts. Doors/flaps for all machine areas provide easy access and simplify servicing and maintenance.

Low operating costs The low power requirement, of the simple yet efficient mechanics keeps energy costs low â&#x20AC;&#x201C; power consumption is in the range 3 - 7 kWh. Servicing costs are low thanks to wellproven technology, reinforcement in places subject to heavy loading, and the fact that the number of moving parts has been reduced to a minimum.

The advantag

Good - Better - RASOR The last treatment stage on the route to refuse derived fuel is usually postshredding. The RASOR stands ready for the job. The RASOR is a postshredder that can do a great deal better than the competition.

Minimal energy use This starts with the material feed using feed screws with load-dependent control. Material is pressed continually against the shredding rotor to attain consistent power consumption – in contrast to competitive products which operate intermittently.

A sharp cut is necessary for fine shredding, meaning a precise cutting gap between blade and counter-blade.

More energy for shredding is required if this gap increases as a result of wear of the cutting tools. This can of course be remedied by reducing the cutting gap with slidable tools - provided it can be done. On the RASOR, this positioning of the cutting edge to the rotor cutters is automated by servo-motors that provide accurate positioning with minimal cutting gap.

The result is permanently lower energy use in the cutting process, something which is of course reflected positively

14

in energy costs. Specific energy costs are up to 30% lower than those of competing products.

High availability Higher rotation speeds and a cutting gap measured in millimetres naturally result in higher tool wear than with a pre-shredder. Tool swap-out should therefore be quick and simple - “time is money” as the saying goes.

The RASOR sets new benchmarks here. Exchange times are minimal thanks to a general decision to stay away from threaded fasteners.

The counter-blade is clamped hydraulically and is easy to exchange.

The positioning already described takes just a few minutes and does not require the system to be shut down.

In the cutter change system on the rotor, a new cutter is pushed hydraulically into the seating slot and the used one ejected. Each cutter can be used twice. The same applies for the screen baskets – they are simply inserted and then positioned by a clamping system.

Fuel from Allgäu The middle of Allgäu (Germany), near Kempten, is home to a company (ALLSO) operating in the climate protection sector.

Climate protection because they produce defined refuse derived fuels for cement works and power stations from commercial and industrial waste – replacing fossil fuels and hence reducing CO2 emissions.

ALLSO (Allgäu commercial waste sorting) is part of the Geiger group of companies and has constructed a streamlined, wellconceived plant that is able to respond flexibly to the different properties of waste and thus extract a maximum level of recyclable materials from the waste stream.

Following pre-sifting, the material is transferred to a pre-shredder and, after Fe separation using a drum screen, is divided up into several fractions.

From this the calorific part is separated using further treatment steps.

The post-shredder then generates an injectable fuel from this fraction.

Retractable counter-cutter carrier provides optimal service accessibility

attributes that give quiet and dust-free operation, which are important criteria in built-up areas.

“The ease of maintenance and simple tool exchange were also decisive, although we are satisfied with the service life of the tools,” Starke adds. Optimal material treatment before post-shredding is of course also a contributing factor.

In the ballistic separation stage, persistent fine parts such as glass, sand and ceramics are mostly shaken off.

With positive sifting, the computer decides what the RASOR is fed.

Depending on input material, 20-30% of the waste can be converted into a product that, within the context of the climate discussion and rising energy costs, is becoming more soughtafter with every passing day.

Post-shredding with the RASOR This treatment stage is entrusted to a RASOR 5400 from Komptech.

“We were aware that this machine was new to the market,” explains COO Andreas Starke, “but after exhaustive scrutiny, we opted for the RASOR.” Material feed is uniform, the shredding area is permanently closed off, and the rotor speed is only about 93 rpm – all

TERMINATOR 5000 UF

The waste solution The UF shredding unit makes the TERMINATOR a perfect waste shredder.

When this unit is integrated into a TERMINATOR 5000, the result is a machine that is virtually unbeatable in terms of cost-effectiveness.

UF stands for Universal Fine, and the name is not accidental. With it, virtually all municipal and commercial waste can be shredded, from household waste to special tyres with thick wire cable reinforcement. This is possible with the combination of drum form

and hydraulic drive. On encountering resistance, the hydraulic unit responds with an increase in torque and, at the same time, the entire tooth force is concentrated only on the engaging tooth thanks to the distribution of the teeth.

Hardly anything stand up to this.

But if it does, the hydraulic overload protection mechanism prevents damage to the tools and the drive.

The contours of drum and opposing comb fit perfectly into one another and produce a shredding result that is adequate for nearly all subsequent treatment stages.

robust scraper prevents wrapping

Attachment with central bolts ensures the solid teeth do not become loose.

The drum tooth can be used 3 times, plating prolongs service life, and easily exchangeable wear rings protect the body of the drum – all factors which minimize costs due to wear.

The TM 5000 has ample power – the rating of 328 kW on the mobile machine (200 kW on the electric variant) is sufficient for a throughput of up to 60t/h. Lack of power is not an issue when filling.

When calculating the overall cost per ton, and seeing just what is possible with the machine, there is jusxt one more decision to make - wheels, caterpillar tracks, hook lift or stationary?
