Extensively equipped recycling systems are available that can be modified in myriad ways, depending upon the specific requirements of the recyclate to be produced.
Coperion’s new Recycling Innovation Center is the perfect complement to the Herbold Meckesheim Test Center, where customers can simulate and test the mechanical pretreatment of plastic, allowing customers to experience first-hand the significant reduction in organic impurities by using Herbold Meckesheim’s hot washing system, as an example.
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 effortlessly scaled up to production level thanks to the constant base parameters of all Coperion technologies.
Every new technological development from Coperion that optimizes plastics recycling has been integrated into the Recycling Innovation Center’s machinery and can be tested there. For example, in the area of 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. Moreover, 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.
