The smartest way to shred plastics

Generated plastic waste can be recycled through shredding, washing and subsequent granulating to produce a recyclable material.

The UNTHA plastic shredders have been developed specifically for this treatment process.

What types of plastic can be shredded?
Plastic fibres and bands

An exact cut is required to be able to efficiently shred filaments, little bands, big bags, fleece materials, ropes and textiles. Our heavy duty plastic shredders are specifically designed to smoothly and efficiently shred even these types of materials.



Specific characteristics and challenges

UNTHA has specifically designed their shredders to effectively process plastic waste to the size required to either be put back into production or sized for other energy use applications.  This ensures the most effective possible recycling solutions for this underutilized waste stream.


The ideal shredder in all conditions

Thanks to the flexibility of our shredders, they are ideal for the different requirements in plastic shredding applications. Due to our range of different cutting systems, rotor diameters, rotor shapes or blade sizes, the machine can be individually adapted and tailored for your material, and therefore for your requirements.

In particular where standardised machines reach their limits, our four-shaft shredders, which have been tried and tested under difficult conditions, come into their own. High reliability and robust resistance to extraneous materials distinguish these plastic shredders.

Single-shaft shredding systems are universal in use, and are able to process a broad range of different materials. It is always possible for you to integrate one of our shredders into your plant, or to operate it as a stand-alone shredding solution.

Discover our full range of applications

The generated plastic waste can be recycled through shredding, washing and subsequent generation of granulate to produce a recyclable material (for the recovery of materials or energetic utilisation).


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
Product destruction

Professional destruction and recycling of waste from manufacturing processes is carried out in the highly sensitive field of product destruction.
