Plastic is a versatile material. Its properties range from tough polymer structures to highly rigid high-tech products. Efficient shredding requires a great deal of experience and expertise.
With thousands of plastic shredders globally, we have addressed nearly every application imaginable. This includes traditional items like start-up purges, crates, pallets, pipes, containers, molded parts, and post-consumer waste such as PET bottles and packaging. Additionally, we handle particularly tough materials like rubber, fibers, films, aramid, Kevlar, and carbon.
WEIMA plastic shredders are extremely flexible and offer different rotor types, rotor geometries and cutting tools. This enables them to properly shred a wide range of thermoplastics such as PE, PP, PVC, PS, PU and PET as well as thermosets and elastomers. Even large-volume hollow bodies, long pipes, massive start-up lumps, and other production waste is processed effortlessly.
With over 40 years of experience in the plastics industry, WEIMA shredders can handle complex materials such as PET bottles, textile fibers, films, insulating materials, floor coverings, crates, and containers. Due to its durability and performance, our machines can efficiently shred production waste allowing it to be reintroduced it into the production cycle. This allows companies to reduce disposal costs and work more sustainably at the same time.
Plastic shredders from WEIMA reduce both disposal costs and the need for expensive new raw materials. By reusing the shredded materials, companies can make their production processes more efficient and sustainable. The powerful, robust and durable WEIMA shredders are ideal for recycling a wide range of plastics.

In-house recycling means that waste from production is reused within the company. This saves disposal costs and expensive raw materials. Waste is usually produced during injection molding, when changing materials or in the case of faulty batches. WEIMA offers shredders and granulators. These devices efficiently shred the waste and prepare it for reuse.
Recycling saves money, shortens delivery times and reduces dependence on external plants. WEIMA helps companies to make better use of their resources and work in a more environmentally friendly way.
HDPE pipes in the plastic cycle
We define post-consumer waste as plastic waste from private use. This includes packaging such as yoghurt pots, PET bottles, bags, films, containers, tubes, toys, labels, fibers and textiles. The increase in global consumption is also increasing the amount of plastic waste. Instead of disposing of this in our oceans or landfill, WEIMA shredders are helping to promote alternative solutions. Together with our partners, we develop single or multi-stage processing concepts to sustainably optimize the plastic lifecycle.

WEIMA shredders are extremely versatile and can be used for a wide range of plastics. Whether your recycling PE film, post-consumer waste or HDPE pipes, WEIMA machines are suitable for a variety applications. Thanks to our innovative technology and adaptable solutions, even the most challenging materials can be shredded and recycled.
Post-consumer packaging film
Shredding plastic waste significantly reduces the use of fossil fuels and raw materials. WEIMA supports companies in increasing their resource efficiency and optimizing the entire life cycle of plastics. The environmentally friendly processing of plastics contributes to a sustainable circular economy and reduces CO₂ emissions at the same time.
Secondary fuel (RDF) from pulper rejects
Plastic waste generated during production is becoming increasingly valuable. As a secondary raw material, it can be fed directly back into the production cycle. The first step in this process is the shredding of production waste such as plastic purge or rejects. WEIMA works closely with customers to find the right solution for their unique requirements, ensuring the best performance for high-quality shredding.
