Process
Collect
Plastic waste is collected from labeled CP3 bins around the Concordia campus and moved to the CP3 workspace for the next steps.
Currently collecting: PLA and PET.
Shred
Plastic waste is shredded to approximately
4-5mm size pellets using an industrial size shredder. These pellets are then sorted by type of plastic and color to ensure no mixing of plastic before being repurposed.
Wash
In the case of major contamination, such as food or chemicals, plastic waste is washed by hand and dried before being repurposed. For filament extrusion, all plastic is washed and dried to ensure the best quality material.
Shape
In the CP3 workspace, plastic waste is transformed into new products, such as key chains, 3D printing filament, cutting boards, etc. A variety of different machinery is available such as the ones listed below.
