Coperion has opened a new test center for optimizing plastics recycling. In the new Recycling Innovation Center for plastics recycling applications, every recycling process step — from material handling and feeding to extrusion, compounding, pelletizing, material postprocessing, and deodorization — can be tested. Extensively equipped recycling systems are available that can be modified in many ways, depending on the specific requirements of the recyclate to be produced.

The Center complements Coperion's Herbold Meckesheim Test Center, where customers can simulate and test the mechanical pretreatment of plastic, allowing them to experience the significant reduction in organic impurities by using Herbold Meckesheim’s hot washing system, as an example. Herbold Meckesheim has been part of Coperion’s Recycling Business Unit since 2022.

The Recycling Innovation Center is located in Niederbiegen near Weingarten, Germany, directly adjacent to Coperion’s existing Test Center for Bulk Solids Handling. Along with proprietary research and development projects, first tests have been performed for customers, in which new, sustainable products and recycling processes have been developed and tested. Coperion process engineers can modify the available recycling technologies such that the recompounds are manufactured with the highest efficiency possible while maintaining a consistently high level of product quality. The results achieved can then be scaled up to production level thanks to the constant base parameters of all Coperion technologies.

New technological developments from Coperion that optimize plastics recycling have been integrated into the Recycling Innovation Center’s machinery and can be tested there. For example, in material conveying, the energy-efficient FLUIDLIFT ecodry flash drying process is available moisture remaining in recycling grinds following the washing process is reduced during material transportation. The MIX-A-LOT bulk solid mixer, which can create premixes including flakes or powders, and the innovative buffer hopper solution using the ARW discharge agitator as well as the Smart Weigh Belt (SWB) feeder are integrated in the system.

Coperion has also installed the ZS-B MEGAfeed side feeder, especially for extruding and compounding plastic recyclates with bulk densities starting as low as 20 kg/m³ at high throughputs. With its innovative design, the ZS-B MEGAfeed handles flakes and fibers such that they can be fed into a ZSK twin screw extruder in large quantities without energy-intensive compacting.

“The new Recycling Innovation Center shows how important it is for us to advance technology that helps our customers work towards more sustainability solutions and a functioning circular economy. The Recycling Innovation Center offers the ideal environment, both for our own research and development projects, as well as for our customers, to master the challenges of plastics recycling,” said Frank Lechner, general manager of Process Technology and Research & Development at Coperion.
