Precious Plastic

We joined the fast growing community of DIY plastic recyclers, based on Precious Plastic open source project. We can now apply our crafts to a material that has been under industrial monopoly for too long.

The injection machine we made is a “primitive” device, it simply heats up the plastic in a tube, and push the melted plastic into a mold using a lever. Heat and pressure are the 2 pillars of injection molding.

Mixed “flakes” of Polypropylene or “PP”, shredded and cleaned before being melted into a new life… When DIY recycling plastics one has to be careful not to mix the different varieties together, so identification becomes a key moment of the process.
