Shop Plastic Recycling Machines and Molds

Citizen Scientific Workshop offers the Polyvora line of Machines for repurposing and recycling plastic into new products. The Basic machines can be operated in a garage, while the Pro machines are designed for locations with increased electrical capacity, such as workshops, small businesses, and universities. We designed the machines for durability, efficient operation, material throughput, and—most importantly—safety.
