GP20 plastic shredder - 3devo

Recycling plastic is crucial for sustainable practices in research and filament production, reducing environmental impact by diverting waste from landfills and conserving natural resources. This supports the circular economy by reintroducing materials into production cycles and offers a cost-effective, eco-friendly alternative for 3D printing filaments. 3devo, a Dutch tech company founded by innovative engineers, specializes in filament extrusion technology with machines like the FM ONE, FM TWO filament makers, and this GP20 plastic shredder.

The GP20 Hybrid shredder

The GP20 Hybrid plastic shredder is a cutting-edge dual-function device that combines shredding and granulating capabilities, advancing from its predecessor, the SHR3D IT. Whereas the SHR3D IT excelled in small-scale projects and research, the GP20 has been optimized for larger-scale applications, boasting approximately triple the processing capacity.

The GP20 was designed to handle a broad spectrum of thermoplastic materials, including commodity pomylers such as PET, PP, PLA, HDPE, PETG, ABS, LDPE, PS and PHB, and engineering materials such as TPU, PCL, PPS, PA6, TPE, PC, POM, PA66, PVA, ASA, PA or PA12. These materials can be commonly found in the following applications:

• PET - beverage bottles, food containers.
• HDPE - milk jugs, detergent bottles, plastic bags.
• PVC - pipes, vinyl flooring, medical equipment.
• LDPE - plastic bags, six-pack rings, various containers.
• PP - packaging, textiles, automotive parts.
• PS - disposable coffee cups, plastic food boxes.
• PEEK - aerospace, automotive, medical sectors.

The GP20 shredder solution is also compatible with high performance polymers such as PEEK, PEKK, PEI, PSU or PPSU, the GP20 offers exceptional versatility. This makes it an ideal choice for various recycling and production projects involving different types of plastics in various industries. An exhaustive guide on material compatibility can be found on the manufacturer's website.
