As a renowned manufacturer of reliable plastics shredders, we offer special machines for in-house recycling and for heavily contaminated post-consumer waste.

Due to its versatility and ease of processing, plastics are very versatile materials that are frequently used in industrial mass production. 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 the processing of plastics. They deal effortlessly with all kinds of plastics, ranging from foils, lumps, profiles, fibres, 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, the shredders are suitable for thermoplastics, duroplastics and elastomers and may be customised to suit your individual requirements.
