The smartest way to shred plastics

Plastic waste is recycled through a process of shredding, washing, and finally granulating to make an extruder-ready product.

UNTHA plastic shredders were developed and have been continually optimized for processing bulk, rigid, and film plastic.

What types of plastic can be shredded?
Plastic fibers and strips

A clean cutting shredder is required to efficiently process fibrous plastics like filament, strapping, supersacks, ropes, and fleece and textiles. Our heavy-duty plastic shredders are specifically designed to smoothly and efficiently shred even these tough materials.



characteristics and challenges

UNTHA shredders are specifically designed to optimally process scrap plastic for recycling, reintroduction into the manufacturing process, or possibly use as alternative fuel. This allows the best use of the materials from this underutilized waste stream.


The versatile shredder

Our versatile shredders are ideally suited to meet the requirements of many various plastic shredding applications. Our variety of cutting systems, rotor sizes, profiles, and treatments mean that a shredder can be specifically adapted for your material, creating the best possible product from your scrap plastic. Our single shaft shredders are available in a range of sizes to process a wide spectrum of materials

Does your material not shred well in a standard single shaft shredder? This is where our four-shaft shredders, used in the most difficult shredding applications, come into their own. These low speed, high torque machines are extremely tough and able to chew through the most difficult materials, even those where traditional plastic shredders give up.

No matter which technology you choose, our shredders can be integrated into your overall plant, or they can operate as a stand-alone system.

Metal shredding is a necessary step in the recycling process, independent of whether your scrap metal comes from the metal-processing industry, the automotive industry, the electrical industry or the waste industry.

Commercial & industrial waste

Commercial and industrial waste is collected separately according to the respective components before being processed and reintroduced into the raw material cycle (recycling), or recovered for thermal recycling or for energetic utilisation (substitute fuels).

C&I waste
Electronic waste (WEEE)

Electronic scrap comprises old electrical and electronic devices, as well as components of these which can no longer be used.

Electronic waste
