Extrusion International 4-2022

55 Extrusion International 4/2022 screw extruder in large quantities with no pre-drying or crystallizing, where they can be processed with the high- est degree of profitability. The ZS-B MEGAfeed can also feed large quantities of post-consumer waste, adding appreciable value to the chemical recycling process with the ZSKs. ZSK throughput rates are very high with the ZS-B MEGAfeed. Preheating of the recyclate via mechanical energy input of the twin screws thus becomes even more economical for further processing in the reactor. Existing Coperion extruders can be retrofitted with ZS-B MEGAfeed technology to greatly expand their spectrum of applications and increase their throughput rates. Marina Matta, Team Leader of Process Technology En- gineering Plastics at Coperion, is enthusiastic about the latest Coperion development: “We’re convinced that the new ZS-B MEGAfeed will play a pioneering role in plas- tics recycling. In particular, plastic fibers, which will be available in ever increasing quantities from textiles, had always been considered hardly recyclable until now. With the ZS-B MEGAfeed, this is now possible. Far more plastic waste can be recycled – and much more efficiently. For the plastics industry, the ZS-B MEGAfeed is another step forward on the path to a circular economy, and we are very proud of that.” Coperion GmbH Theodorstr. 10, 70469 Stuttgart, Germany www.coperion.com The significantly improved plastic fiber and flake feed rate using the ZS-B MEGAfeed side feeder leads to enormous throughput increases when recycling plastics with a Coperion ZSK twin screw extruder
