[Article from ScrapBook Autumn 2010]
A.T.U Auto-Teile-Unger is a German company specializing in auto retail stores and integrated, brand-independent workshops. Parent company is the A.T.U Auto-Teile-Unger Handels GmbH & Co. KG and for the environmentally friendly disposal of the garage waste A.T.U has an own subsidiary, the ESTATO Umweltservice GmbH. A.T.U has been active with recycling for almost 20 years.
Since 1992 A.T.U has been separating the usable materials from the unusable, and then reusing them in a suitable way. In 2000 ESTATO built up a 50.000 m² big recycling plant with modern recycling technology to make further use of the materials benefits: “Intelligentes Recycling – Modernste Technik” (Intelligent Recycling – Modern Technology). They recycled for example metal scrap (catalysers, brake discs, batteries and so on for sale to scrap dealers), oil filters (for shredding, de-oiling and take out the ferrous-scrap), draining shock absorbers and pressing the package with a baling press to sell the paper to the paper industry. An additional part of the environmental concept was the truck washing machine which works only and solely with rain water. But definitely the biggest part of the waste ESTATO had to deal with were tyres. They already sorted out the good from the bad ones, and resold the good, and burned the bad in the cement industry. In 2001 they became interested in a better solution and began looking for a way to recycle the bad tyres themselves.
When getting in contact with Eldan Recycling they did not have any special requirements, as they where new within tyre recycling. After discussions they set the input requirement as about 3 tons per processing hour, and the output as different kinds of clean rubber ready to sell. The price level of the equipment should be lower than the larger competitors.
Eldan Recycling first got in contact with A.T.U in 2000. It was then owned by Mr. Peter Unger and had about 8.000 employees and 300 shops.
In 2001 A.T.U bought its first tyre recycling plant from Eldan Recycling. It was a standard plant (type E4000T) including among others, a Super Chopper, a Tumble Back Feeder, a Silo V4, two Fine-Granulators and an Aspirator.
In 2002 a second Super Chopper was purchased for the new ssorting centre in Werl. The Super Chopper reduced the tyre volume before transport to Weiden, and thereby also reducing transporting costs. During this year the company also purchased a second tyre plant (type D4000T) from Eldan, additional to plant 1. The difference between the first and second plant was basically that they did not need one more Super Chopper, since the first one had the capacity to supply both tyre plants with shredded tyres.
In 2004 the third Eldan tyre recycling plant was purchased. This time they chose the plant including the Super Chopper since the first Super Chopper could only supply two Tyre Plants if maximum capacity was desired.
From 2004-2006 additional cleaning equipment for the plants where purchased. The cleaning equipment consisted of a Gravity Separator (C26), a sorter (PC 1000), a Cyclon cleaner (KIA 20 or 60) and an Aspirator (type 1250). “Since the customer desired higher quality of the rubber granulate we developed additional cleaning equipments (C26, PC1000, KIA, ASP) together with A.T.U.” says the A.T.U responsible agent at Eldan, Mr Dieter Ickenroth.
In 2006 A.T.U felt that the first tyre recycling facility was becoming overcrowded. A new building was build in close proximity to the first one. In 2006-2007 three new tyre recycling plants (D4000T) were purchased from Eldan for the new building. In 2006 A.T.U also purchased wire cleaning equipment (TBF, MPR 120 and Vibro-Separator Magnet) from Eldan. “A.T.U also desired cleaning equipment for wire scrap (TBF, MPR120, Vibro–cleaner, Magnet) which we also developed together with them” says Dieter Ickenroth. “All product development made at Eldan is based in what our customers need. This is the reason why we develop them together with the customers. That way they get exactly what they want and need” says Bjørn Laursen, product manager for tyre recycling at Eldan Recycling.
During 2010 additional wire cleaning equipment will be installed. From 2001 until 2010 A.T.U has acquired six tyre recycling plants and cleaning equipment from Eldan Recycling.
A.T.U mentions four main reasons for choosing Eldan as the supplier of their tyre recycling equipment.
First A.T.U were convinced that Eldan knew what they talked about when they presented the idea behind the recycling plant. The meeting between A.T.U representative, Mr. Josef Hösl, managing director at Estato Umweltservice GmbH and the agent representing Eldan – Dieter Ickenroth, made A.T.U very interested. The idea behind the plant was intriguing.
Second they where interested in the arrangement of the single parts, i.e. the change between crushing and cleaning.
Third the Eldan machines contain a high number of changeable parts (in for example the Heavy Pre Granulator/Multi Purpose Rasper and the Fine Granulator). Due to the content of the material processed (rubber, steel and textile) and the fact that the steel wear on the knives it is important to keep up the maintenance on the machines in order to maintain the quality of the output. The high number of changeable wear parts keeps up the great output quality. Since the parts of the machines that suffer the most stress are changeable, the machine will last longer.
“To be able to run a 24-hour-a-day-business we rely on the guaranteed advice, support and service from Eldan” Josef Hösl, managing director at Estato Umweltservice GmbH
Finally the fact that Eldan had a plan for the plant to fit one building / floor, and therefore making the recycling work easier also had a big impact on the decision making.
“To be able to run a 24 hour a day business we rely on the guaranteed advice, support and service from Eldan” says Mr. Josef Hösl, ”By using Eldan Recycling equipment we get all equipment from one supplier. Eldan has the competence that we need. We have a personal contact which we always can reach”
“Today A.T.U / Estato is one of the largest tyre recycler in Europe, and Eldan Recycling is proud of being a part of that success story. We feel that our collaboration will be fruitful in the future as well” says Mr. Bjørn Laursen.
Mr. Josef Hösl has noticed a change in demand for recycled steel wires from tyres: “We have noticed a big increase in demand for recycled steel wires. The recession has changed the business for many companies. We have sold a lot more recycled steel wires to steel works. The steel works can not get a hold of the steel in their usual channels, and therefore searched for alternatives. They are very satisfied with the result from the Eldan steel cleaning equipment.”
