Dekasan Utilises WEIMA Shredder for RDF Production

In Bursa, Turkey, Dekasan Waste Management relies on a WEIMA PowerLine 2000 single-shaft shredder to process industrial waste, including materials containing hazardous and toxic substances. Since 1982, the Turkish company Dekasan has provided waste management services. Located in the Kayapa industrial zone in Bursa, western Turkey, each year Dekasan collects, separates, or recycles over 20.000 tons of household and industrial waste of various kinds. In April 2024, the company expanded its operations by introducing a processing line for hazardous waste from industrial processes. Waste from rubber, plastics, textiles, chemicals, paint products, and containers contaminated with toxic substances is converted into refuse-derived fuel (RDF) using a WEIMA PowerLine 2000 shredder. The high-calorific RDF is then sold to cement manufacturers in the region.

The waste is delivered by truck and fed into the shredder via a gripper. The PowerLine 2000 shredder, equipped with a 315 kW hydraulic drive from Hägglunds Bosch Rexroth, reduces the material to a uniform particle size of 50 mm. With a working width of 2,000 mm and a rotor diameter of 800 mm, the PowerLine series is ideally suited for single-stage shredding of various waste types. The robust construction of the WEIMA shredder excels under these fluctuating material streams and demanding conditions.

“Depending on the material, we achieve throughput rates of four to nine tons per hour,” explains Environmental Engineer Tolga Bo'nak, who was responsible for acquiring the shredder and establishing the new RDF line.

Dekasan also installed an injection system to moisten the material within the hopper area during shredding. This results in a significant reduction in dust in the production hall, creating a safer and more comfortable work environment for employees. The shredded material is conveyed via a belt and passes through a metal separator. Before transport, Dekasan conducts a chemical analysis of the shredded material in its in-house lab. Depending on customer specifications, the calorific value can be adjusted by blending different batches. Industrial and hazardous waste is not only particularly abrasive and challenging to shred but often contains disruptive materials such as metal. If these materials enter the shredder, it automatically shuts down. Through the hydraulic inspection flap, the materials can be easily removed, allowing the machine to be quickly restarted, reducing downtime.

To further minimise downtime, Tolga Bo'nak opted for a service agreement with WEIMA. Quarterly, a WEIMA technician inspects the shredder thoroughly. In addition, adjustment parameters can be remotely configured as needed. The decision for a WEIMA shredder was based on multiple factors. Unlike other offerings, WEIMA was able to handle the required task with a single shredder instead of a pre- and post-shredding system. This not only saves space in the production hall but also reduces acquisition and maintenance costs. Additionally, the robust hydraulic drive with its variable speed range, the machine's reliability, and the serviceoffered were decisive factors.
