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.

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.

Another Herbold Washing Line in the UK

Herbold Meckesheim supplies a plant with an input capacity of approximately 10.000 tpa for film recycling in England. It is designed for 100 percent post-industrial stretch film. A demanding application for wash lines, as it represents an extremely high surface area and low bulk density.
