Extrusion International 4-2023

53 Extrusion International 4/2023 should be another person's raw material. Expert Re- cycling wants to support a society focused on sustain- ability with state-of-the-art technology that is not only safer but also more efficient than before. Ulti- mately, we need to significantly increase the recycling rate." To achieve these ambitious goals, Expert Recycling re- lies on shredding technology fromWEIMA in Germany – distributed by the Romanian dealer Chorus Engineering from Bucharest and co-financed by funds from the Eu - ropean Union. In the first step of the recycling process, the WEIMA W5.18 plastic shredder W5.18 processes a wide variety of films, packaging and more to a homogeneous flake size, which is ideal for further processing. WEIMA shredder as the central component The WEIMA shredder as the central component of the recycling line has a working width of approx. 1,800 mm, with a rotor diameter of approx. 500 mm. It is driven directly by a Hägglunds Bosch Rexroth hy- draulic power drive train, without gearbox or frequen- cy converter, which allows consistently high through- put rates to be achieved. The drive is extremely robust with regard to foreign objects and features variably adjustable rotor speeds with constantly high torque – even under full load. The material is fed via infeed conveyor belt. The com- pact swing-arm ram installed inside the shredder press- es the material to be shredded against the rotor in a load-dependent and fully automated manner. Due to the wide opening of the inspection flap, the removal of any impurities or the maintenance of the cutting geom- etry is conveniently possible at any time. After shredding, the flakes are washed, followed by extrusion using a solution from Erema. The products, var- ious regranulates and film products, are of the highest quality, confirms Dan Ana: "We collect or buy post-con - sumer as well as post-industrial plastic waste fromour nu- merous partners. All our products, granules, household waste bags and films, are made of 100 percent recycled material and comply with all EU regulations, including CE marking for full transparency in national and interna- tional markets. At Expert Recycling, we have a compre- hensive technology park for end-to-end recycling. This includes sorting, separating, washing, shredding, baling and extruding. And we're pretty proud of that!"
