Coperion and Herbold Meckesheim to present complete solutions for plastics recycling at K 2022

Complete systems for industrial-scale plastics recycling from a single source – the recently completed merger between Coperion and machine manufacturer Herbold Meckesheim makes it possible. Coperion, technology leader in extrusion and compounding, bulk material handling and feeding systems, brings its own expertise in the field of recycling together with that of Herbold Meckesheim, specialist in the mechanical recycling of plastic and plastic waste, forming a new Recycling Business Unit.

In the beginning is the shredder

For use in plastic recycling plants, the demand for powerful shredders has grown. Especially those that can process entire bales at the beginning of the reprocessing chain. Modern washing plants in particular, such as produced by Herbold Meckesheim, require sophisticated shredder technology to be able to process high throughputs and challenging feed materials. At the same time, the machines should be largely wear-resistant and as simple as possible to operate and maintain.

Plastimagen México – Herbold Meckesheim verzeichnet Zurückhaltung auf dem Gebiet des Recyclings

On an area of around 34,000 square meters, 480 companies from 23 nations presented themselves at the Plastimagen in Mexico City. The industrial show is considered the flagship fair of the plastics industry in Latin America. Among a total of 13 pavilions, eleven of them country-specific, Europe in particular was strongly represented.

First the mechanics, then the chemistry

The agreement is rightly called historic: Recently, the United Nations Environment Assembly (UNEA) passed a resolution providing a global agreement to curb plastic waste. By the end of 2024, a legally binding convention is to regulate the entire life cycle of plastics. Bitterly necessary, after all, according to UN figures, around 400 million tons of plastic waste are generated worldwide every year, of which only about nine percent is recycled.

Herbold washing plant gets to the heart of PP hard plastics

The primary production of one metric ton of polypropylene – the world’s second most widely used plastic – requires some 5.2 metric tons of raw materials and releases 1.7 metric tons of greenhouse gases. By contrast, the use of one metric ton of polypropylene from secondary raw materials, such as plastic waste, results in only around 225 kilograms of resource consumption and just under one metric ton of greenhouse gases.
