Precious Plastics designs, sells and operates plastic processing and recycling equipment, including crucibles, presses, extrusion presses, sheet presses, injection molding machines, shredders, graders. You can buy the equipment or download the drawings for free, it's open source.
Precious Plastics operates a partner network of plastic recyclers and processors. Especially in developing countries where industrial scale recycling infrastructure doesn't already exist, this allows plastic recycling to happen in situations where it would otherwise go in a landfill.
Precious Plastics has a small, human centric ideal embedded in its culture and messaging. It's based around the idea of a small machine in a garage operated as a hobby with others in the local community, not a vertically integrated industrial behemoth.
Does that cover it well?
