Filtration compounder for polymer recycling

Streamlines Filtration and Compounding in Recycling

The ZSK FilCo Filtration Compounder by Coperion revolutionizes recycling with a unique system that integrates filtration and compounding into a singular production step. Designed for polymer processors and recyclers, this equipment simplifies the processing of post-consumer recyclate and highly contaminated polymers. Working with the ZSK twin screw extruder, the ZSK FilCo melts, homogenizes, and devolatilizes plastic waste before filtering out contaminants. This processed melt is reintroduced for compounding with various fillers or reinforcing materials, such as glass or carbon fibers.

Applications span across the recycling of diverse plastics, culminating in high-quality products like pelletized plastic recyclate and fiber-reinforced composites. This system notably reduces energy consumption and emissions by over 50% compared to traditional methods, due to its streamlined design that eliminates the need for multiple melting processes. The ZSK FilCo handles solid, granule, and film flake inputs, all while maintaining continuous, high-speed operation. Compact and efficient, it offers consistent quality improvements and reduced thermal stress on polymers, making it a crucial asset for sustainable materials manufacturing.
