We provide the know-how for the fight against the global plastic waste problem.
What is Precious Plastic about?
Precious Plastic was initiated by Dave Hakkens, a designer from the Netherlands, during his studies at the Design Academy Eindhoven in 2013. Given the widespread problem of plastic pollution and the limited possibilities of conventional recycling, Hakkens developed an approach that enables people all over the world to process plastic waste locally.

Development of a compact shredder for plastic waste
In collaboration with Precious Plastic, WEIMA has developed a new version of the “Shredder Pro” for the global recycling community in recent months. The particularly compact shredder consists mainly of standard parts and is designed to be easy to reproduce. It is ideal as an entry-level machine for people who want to start their own small recycling business but still want to achieve certain throughput targets. The shredder can also be used for projects in developing countries and educational institutions thanks to its low connected load of just 3 kW and particularly simple operation.
The drawings are freely available as open source for rebuilding:
Nominated for Recycling Machinery Innovation Of The Year by PRSE Awards
We’re honored to be nominated by the PRSE 2025 show in Amsterdam for “Recycling Machinery Innovation Of The Year”. The Shredder Pro was developed by WEIMA in collaboration with Precious Plastic, the popular open hardware plastic recycling project that allows creating new products out of recycled plastic on a small scale – for start-ups, educational purposes and emerging economies to tackle the global plastic pollution problem.

Official Precious Plastic Workspace for live demos and training purposes
Explore and enlighten.
WEIMA operates a Precious Plastic workshop at the company headquarters in Ilsfeld. It was specially designed for workshops and consists of a shredder and an injection moulding machine. The plastics recycling process can thus be experienced live by college and high school students, and other interested parties.
Cooperation with the State Academy of Fine Arts (ABK) in Stuttgart
In winter 2024, WEIMA provided the ABK in Stuttgart with a Shredder Pro and a compact injection molding machine. In the plastics workshop, students can use these recycling machines experimentally and productively for material tests, prototyping and more as part of product design. The machines were used for the first time in the industrial design project “Ripped-Up” with artist Sofia Souidi.

Presentation of the Shredder Pro at the K trade fair in Düsseldorf
WEIMA is also promoting the topic of small-scale plastics recycling at international trade fairs – for example at the K trade fair in Düsseldorf, where the prototype of the Shredder Pro was presented with the personal support of Precious Plastic.
We are happy to support you.
