Safely Managing Hazardous Waste: Dekasan Utilizes WEIMA Shredder for RDF Production

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. 

Throughput of up to 9 tons per hour

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. 

Improved working conditions through dust reduction

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.  

Reliable operation with intelligent shutdown system

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. 

One shredder, many advantages

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.
