Shredder

What is it?

The Shredder is a machine Buckeye Precious Plastic has designed to shred recyclable plastics into smaller flakes for use in our other machines. Using a bicycle powered single-shaft shredder, plastic is sized into small, uniform pieces to facilitate consistent melting and easier storage. It doubles as a demonstration activity during events so that the public can interact with our machines and learn about the recycling process. The shredder is largely based off the V3 Shredder from the open source community, Precious Plastic, and consists of 5 main sub-assemblies: hopper, shredding box, base/collection, bike, and transmission.
