Groundbreaking Technology: Catalysts Revolutionize Mechanical Plastics Recycling

Berlin, Germany - German-based Coperion, a leading provider of plant solutions for mechanical plastics recycling, is making significant strides towards converting plastic waste into high-quality raw materials. By utilizing advanced technologies and catalysts, the company aims to overcome energy-intensive processing methods that often result in lower product quality.

A new research project at the University of Utrecht, spearheaded by Professor Vollmer's team, focuses on improving end product quality and process efficiency through the use of catalysts. The STS 25 Mc11 twin screw extruder, recently installed at the university, enables precise processing of shredded or compacted plastic waste with high shear and intensive dispersion. This results in a thorough mixing effect, efficiently melting the plastic without significant energy waste.

Key to the breakthrough is the homogeneous distribution of catalysts throughout the plastic melt, allowing for optimal utilization of their intended functions. Researchers are optimistic about the potential of this technology to achieve "unlimited recycling" by converting an expanding amount of plastic waste into valuable raw materials.

Another significant challenge addressed by the research project is minimizing energy needs during pyrolysis, a subsequent step in chemical processing that breaks down plastics into their building blocks in an oxygen-free environment. Preliminary data shows that catalysts can significantly lower temperatures under optimal conditions, bringing the process closer to industrial viability.

While challenges persist in scaling up and refining this technology for widespread adoption, Coperion's innovative approach has sparked hope among researchers and industry experts that it may soon transform the field of mechanical plastics recycling, offering a more sustainable solution to tackle global plastic waste management.
