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 know-how.
With many thousands of plastic shredders delivered, there are hardly any applications that we have not already implemented. These include classic items such as start-up lumps, crates, pallets, pipes, containers, moulded parts and post-consumer waste such as PET bottles or packaging. But also particularly tear-resistant materials such as rubber, fibers and films, aramid, Kevlar or carbon.
The compact classic with conveyor belt cut-out
The proven multi-talent with 1,500 mm working width
Maintenance-friendly all-rounder with swing ram
Highly productive with extra-big 700 mm rotor diameter
Universal high-capacity machine with 3,000 mm working width
WEIMA plastic shredders are extremely flexible and offer different rotor types, rotor geometries and cutting tools, whereby they can shred a wide range of thermoplastics such as PE, PP, PVC, PS, PU and PET, as well as various thermosets and elastomers.
Even large-volume hollow bodies, long pipes and profiles, massive start-up lumps and other production waste, as well as PET bottles, textile fibers, foils, insulating materials, floor coverings, crates and containers master industrial WEIMA shredders effortlessly thanks to 40 years of experience in the plastics industry.
"With the high volumes of plastic waste in the world, sustainable disposal concepts are particularly needed. And shredding is the basis for this."

In-house recycling and post industrial plastics processing
as part of the Circular Economy
Plastic waste generated during production is becoming increasingly valuable. As a secondary raw material, it can be returned directly to the production cycle. The first step in this process is the shredding of production waste such as start-up lumps or reject parts. WEIMA works closely with customers in order to find a suitable solution for the most diverse plastics. This way we ensure that even materials that are difficult to process are shredded into high-quality regrind.
With the right technologies, production waste can be reprocessed into new raw material. Thus you save high raw material costs, reduce long delivery times, avoid expensive disposal in external recycling plants and avoid the use of primary resources in the long term.

Post-consumer waste means plastic waste from private use. This includes packaging such as yoghurt pots, PET bottles, bags, films, containers, tubes as well as toys, labels, fibers and textiles. Due to the increase in global consumption, the amount of plastic waste is also increasing. Instead of disposing of it in our oceans or landfills, WEIMA shredders contribute to the promotion of alternative solutions. Together with our partners we develop single or multi-stage processing concepts in order to optimize the plastic lifecycle in the long term.
Both concepts have the same goal: to extend the plastic life cycle. In recycling, plastic waste is usually shredded and transformed into regranulate by extrusion, e.g. to produce new PET bottles from old PET bottles. In upcycling, on the other hand, one tries to give supposedly useless plastics a new, higher-quality sense, either alone or in combination with others, e.g. bags made of packaging strings.
In order to ensure the recyclability of plastic products, disposal or recycling must be considered even before production begins. The term Design for Recycling (D4R), or recycling-friendly design, refers to the holistic conception and design of products that can be optimally returned to the recycling loop after their use. In this context, plastics in products should be combined in such a way that a clear separation of the different types is possible at the end of their life. This is the only way to keep waste streams pure and ensure their recyclability and thus their reuse as secondary raw materials.
For example, a German cleaning product manufacturer fills detergents in environmentally friendly refill bags. These are made of 100 percent polyethylene (PE) and contain neither adhesives nor bonding agents. The printed band can be separated from the packaging, making the bag 100 percent recyclable. Another feature is that the packaging is made entirely from recycled plastic.
The WEIMA show room is equipped with shredding and briquetting machines of all sizes and technologies. This enables us to simulate your application as realistically as possible. You have the possibility to send us your material or visit us directly in Ilsfeld. From our gallery you have the best view directly into the cutting chamber. So you can observe the shredding process live.

Butler-MacDonald, Inc. is an American plastics recycling specialist which takes great pride in processing hard-to-handle plastic scrap from various sources, including post-industrial and post-consumer waste streams.
Marcel Alberts has declared war on so-called Ghost Nets – left-over, floating fishing nets and ropes that pollute the world’s oceans. Using state-of-the-art technology for plastics recycling, the aim of his Dutch company Healix is to turn this linear waste into a product on site and create a circular economy. At the forefront of the process chain is a WEIMA W5.22 single-shaft shredder.
Romanian recycling company SuperBon uses a primary shredder and two secondary shredders for its production of plastic recyclates before selling the raw material worldwide.
Not all plastics are the same. Some materials pose greater challenges for recycling companies. WEIMA, the shredding specialist from Ilsfeld, has the perfect solutions for this. With two WEIMA WLK 15 Jumbo single-shaft shredders, Inoplast Kunststoff GmbH will in future be able to shred even the most technically demanding source material for the recycling process.
