< PREFACE

Eelo Gitz

WIEFFERINK HAS BEEN IN BUSINESS FOR SIXTY YEARS NOW – A MILESTONE WHICH IS REASON FOR A SMALL CELEBRATION. THE JOURNEY SET OFF IN 1956 WHEN FOUNDER MR. HENNY WIEFFERINK STARTED REPAIRING SHOES AND MAKING SADDLES IN AN EMPTY CHICKEN BARN IN THE EASTERN NETHERLANDS. SINCE THAT TIME, MUCH HAS CHANGED. WIEFFERINK HAS GROWN TO BEING AN INTERNATIONALLY ORIENTED SUPPLIER OF FLEXIBLE COVER AND STORAGE SYSTEMS.

We work on products with diverse applications in agriculture, energy production and industry. Our portfolio is varied: from the storage of manure and gas in biogas installations to flexible water depots. The company is built on craftsmanship, since many of the steps in production and mounting can’t be automated. Our dedicated team consists of people who know how to roll up their sleeves. As well as people who use their expertise to develop new products and applications.

Going international is an important part of our mindset. The centre of gravity of our activities lies in Europe, but we also worked on some exciting projects in countries farther away, such as Guatemala, Thailand and South-Africa. In this magazine, we would like to offer you glimpses of some of these projects.

All in all, our team works towards one common goal: to leave the world a better place. We hope that you will get an impression of how we are trying to achieve this goal.

I wish you a pleasant reading.

< HISTORY ESTABLISHED SIXTY YEARS AGO BY A SINGLE MAN, WIEFFERINK HAS SINCE GROWN TO A COMPANY WITH JUST UNDER A HUNDRED EMPLOYEES AND AN INTERNATIONAL CLIENTELE. FROM THE START, WIEFFERINK HAS BEEN ABLE TO ADAPT ITS PRODUCT PORTFOLIO TO MEET THE NEEDS OF THE TIME.

Henny Wiefferink founded the company in January 1956. In an empty chicken barn in Denekamp, he started repairing shoes and making saddles. Gerard Gortemaker is the employee with the longest tenure with Wiefferink: forty years. He tells about the company’s history.

“Wiefferink soon shifted his focus from shoes and saddles to the manufacturing of among others tarpaulins, big bags and sun blinds. The raw material for these products was polyester cloth with a particular coating. Wiefferink bought the material, which was cut into pieces and stitched with a sewing machine to get the right shape.

As the products became larger and larger, the chicken barn soon got too small. New production halls came into use.

In 1987, Henny Wiefferink decided to sell his company because of poor health. The production units for tarpaulins and industrial confection continued under the name Wiefferink, whereas the production of sun blinds was stopped.

Silo cover In 1988, a pure coincidence led to an important step for the future of the company. One of the local customers, a transport company which purchased tarpaulins for its trucks, asked Wiefferinks owners to make a cover system for a silo with manure. Wiefferink developed a system and became market leader with this product, first in the Netherlands and later worldwide.

Gerard Gortemaker

In the early 1990s, new legislation in the Netherlands gave a boost to the sales of silo covers. It became an obligation to cover silos with manure. Wiefferink took care of covering thousands of silos, including mounting.

Meanwhile, continuous growth urged the company to move to a new building in Oldenzaal, which has been Wiefferinks residence until this day.

Biogas When the market for silo covers was almost saturated at the end of the 1990s, Wiefferink started developing a new product in cooperation with BTG from Enschede.

They developed the idea to use a double layer – instead of a single layer - of polyester foil to cover silos with manure. This system would enable the capture of gas, so it could be used in biogas installations.

The first cover system was completed in 1998 and soon became successful, particularly in Germany. During the so-called “Grüne Wende”, the German government provided subsidies to farmers who produced sustainably. This resulted in an enormous increase in biogas installations. Wiefferink delivered covers for many of these facilities.

Poland In 2008, a new round of expansion took place when a new production hall was built in Wykroty, Poland.

The gigantic hall allows the manufacturing of huge products. At present, Wiefferink delivers a wide range of products for the agricultural, biogas and industrial market around the world.”

< TAILORED MADE (FOR YOUR NEEDS) WIEFFERINK HAS A TEAM OF JUST UNDER HUNDRED DRIVEN PROFESSIONALS DIVIDED OVER TWO LOCATIONS IN THE NETHERLANDS AND POLAND. THE COMPANY DOESN’T HAVE ANY TURNKEY PRODUCTS IN STOCK; EVERY PRODUCT IS ADJUSTED TO THE CUSTOMER’S SPECIFICATIONS. DIFFERENT DEPARTMENTS, SUCH AS R&D, SALES, PRODUCTION AND MOUNTING WORK CLOSELY TOGETHER TO OBTAIN THE BEST RESULT FOR EACH CUSTOMER.

Sales Wiefferinks sales team works with around thirty dealers of agricultural products and with agents in several countries. Partnerships with contractors contribute to smooth-running construction of biogas installations.

Wiefferink also participates in regional and international fairs related to agriculture and industry. The sales team members make sure the product is tailored to the needs of the customers, not just with regard to the technical aspects, but also to delivery and pricing.

Business office Employees at the business office perform all steps needed in the preparatory phase. One of their tasks is to buy all the materials, from the foil to the materials needed for mounting such as bolts and nuts. For the silo covers, Wiefferink determines the exact specifications of the foil in cooperation with engineering agencies. The decision is based on calculations of wind and snowfall values for the location and on the diameter of the silo: the larger the building, the heavier the material. Wiefferink also, apart from their own R&D/engineering, consults engineering agencies to decide on the optimal coating.

Production Leo Bekhuis is head of the Dutch production department and tells about the process. “Based on the drawings, our production employees cut the foil with the aid of computer operated cutting machines. Next, they use different types of welding techniques to fasten the pieces together. Additional elements such as inspection openings, valves and electric mixers are added. All the products are thoroughly tested and inspected before use. To this end, we

have developed our own testing facilities and quality programmes.

Wiefferink has KIWA and ISO 9001: 2008 certifications.”

Mounting Wiefferink can take care of every step in the logistics and mounting process. Arranging a hoisting crane is one of the possibilities. To meet this need, the company has a pleasant cooperation with Kuiphuis Kraanverhuur, a rental company of cranes residing in The Eastern Netherlands.

Mounting employees travel around the world to install the products.

One of them is Timothy van Oosten, who has been working with Wiefferink for almost thirteen years. He has worked on exciting projects in faraway countries. Van Oosten: “In Kazachstan, we installed a storage system in the middle of a desert while it was minus twenty degrees Celsius. Unfortunately, the earth bank supposed to shelter the bag had been blown away. Therefore, the installation took more time than normal. Nevertheless, I really enjoy this work.”

< ECOBAG AND COMBIBAG PRODUCT INNOVATION IS A KEY ASPECT OF WIEFFERINK. THE COMPANY WORKS CLOSELY WITH ITS CUSTOMERS TO DEVELOP NEW IDEAS, PRODUCT APPLICATIONS AND CUSTOMISATIONS. MEANWHILE, WIEFFERINK DOESN’T SHY AWAY FROM TAKING UP LARGE PROJECTS AND IS WILLING TO EXPLORE THE LIMITS OF WHAT IS TECHNICALLY FEASIBLE. THE ECOBAG AND COMBIBAG ARE TWO OF THE PRODUCTS WHICH HAVE BEEN INNOVATED RECENTLY.

Ecobag The Ecobag is a flexible storage system for manure, digestate and other liquid waste flows. It can be used, for example, as a storage option when spreading manure is not permitted, or for the storage of digestate in combination with a biogas installation. The Ecobag prevents emission of CO2 and other gases and keeps rain water away. Due to the low height of the construction and its grey or eco-green colour, the Ecobag blends well into the landscape.

Recently, Wiefferink has manufactured Ecobags with a stunning surface of half a football field. This storage system has a volume of 10.500 m³ and weighs eleven ton. The employees of the production hall in Poland used a special production method to make these Ecobags.

Combibag The Combibag is a flexible storage for up to 8000 m³ of manure and digestate, which captures the gases released during the digestion processes. It can be used for example for secondary fermentation next to a biogas installation, or for storage of liquid waste flows with gas formation. The Combibag contains an overpressure valve and an electric mixer.

Wiefferinks Research & Development department has recently developed a new round shaped Combibag. Two employees at this department, Peter Mulstege and Tomas Syrnik, explain the advantages. Syrnik: “Due to some changes to the system,

Wiefferink manufactures Ecobags with a stunning surface of half a football field

we can handle higher pressures in the new Combibag as compared to the old one.

Another advantage is that the new Combibag can contain a much bigger gas volume.

As compared to an old Combibag with an equal ground surface, the new bag can thus hold a higher quantity of gas.”

Unique projects In the beginning of 2016, two hitherto unique projects were carried out, both of which involved a combination of a gigantic Ecobag and a Combibag. These projects took place in Belgium and the UK. In Belgium, a biogas company uses the 10.500 m³ Ecobag for the storage of digestate, in combination with a biogas installation and a 7.200 m³ Combibag for secondary fermentation. A tomato grower in the UK utilizes the same combination of Ecobag, biogas installation and Combibag. The projects are unique because these Ecobags are the largest completely closed depots of manure in the world.

< CUSTOMERS AT SPEECH TWO OTHER PRODUCTS THAT WIEFFERINK OFFERS ARE THE FLEXITANK AND SILOCOVER. THE FORMER IS A FLEXIBLE STORAGE SYSTEM, WHEREAS THE LATTER DOES WHAT THE NAME SUGGESTS – IT COVERS SILOS.

Flexitank The Flexitank is designed to store a wide range of liquids. It can be used for instance for potable water, wastewater, liquid buffers for industrial use and even fossil fuels. Wiefferinks Flexitanks are used among others by water utility companies for both emergency drinking water provision and regular drinking water supply.

One of the users of Wiefferinks Flexitanks is MTD. This company provides temporary water infrastructures for both drinking water and waste water. MTD uses the Flexitanks at festivals, big international sporting events and industrial projects. MTD has been a customer of Wiefferink for more than seven years and use Flexitanks with volumes of 20, 50 and 100 m³.

Advantages David Jones, Fleet Manager at MTD, thinks these flexible systems have many advantages over tanks. He explains: “When unused, the Flexitank can be folded into a small light-weight package, which makes transport very easy.

Therefore, this system is a good solution for temporary liquid storage or storage in remote locations. Another asset of the Flexitank is that it gets recycled. Once a year, Wiefferinks employees clean both the inside and outside of the Flexitanks. After that, they are treated with gamma radiation to kill bacteria. Thus, the Flexitank is environmentally friendly.” The cooperation between MTD and Wiefferink has been satisfactory so far. Jones: “Wiefferinks team members are always willing to sit with us and think about the best solution for our circumstances. This resulted into further development of the Flexitank in such a way that drinking water certification was granted.”

installs precast concrete storage tanks, for example for

such as concrete, steel and plastic ones. It is available in a gas-tight and a non-gas-tight version. The gas-tight version can be used for the storage of gas derived from manure or waste streams of biogas installations. One of the loyal purchasers of Silocovers is the company A-Consult. This company designs, manufactures and storage of water or manure. Operating from offices in Denmark, Germany and United Kingdom, the company has installed over 8000 tanks across Europa in the last thirty years.

Good cooperation A-Consult has worked closely with Wiefferink since 2002, and has installed their Silocovers on close to 1000 tank structures, primarily in the agricultural sector. Managing Director Søren Østergaard is satisfied with the cooperation. “We have good experience with the quality of the Wiefferink covers, and are pleased with the co-operation we have with and service we get from the team”, Østergaard says.
