As a renowned plastic shredder manufacturer, we offer reliable shredding solutions for in-house recycling, post-industrial, and heavily contaminated post-consumer plastic waste.

Due to its versatility and ease of processing, plastics are very versatile materials that are frequently used in industrial mass production and many consumer products. The waste plastic generated can be recycled through shredding, washing, and subsequent granulating, thus producing a reusable recycled material. Aside from recycling, plastic waste can be used for energy generation after shredding.

Our shredders were developed specifically for shredding plastics. They deal effortlessly with all kinds of plastics, ranging from film, lumps, profiles, fibre, ribbons, PET bottles and hollow parts to post-consumer and production waste. Thanks to a range of different cutting systems, rotor diameters and shapes as well as different blade sizes, our plastic shredders are suitable for thermoplastics, thermosets, and elastomers and are customizable to suit your individual requirements.
