    Out of the factory and into your home – here’s to recycling your own plastic with Precious Plastics.

    Think of plastic as a precious commodity that, like the oil it’s made of, might not be around for ever. Now, how would one preserve this commodity and increase its lifespan?

    Well, the team behind the Precious Plastics project spent two years developing machines. They help people to recycle waste locally and get the most out of plastic products. Once recycled, people can use the plastic to create new products through processes such as 3D-printing and injection moulding.

    The machines are easy to build. The machines can be built with basic tools and materials available to the average consumer. The blueprints are even free to download from the Precious Plastics website.

    The Precious Plastics machines include (from left to right):Precious Plastics recycling machines

    Extrusion machine: This machine creates a continuous line of plastic and can create 3D-printing filament.

    Shredding machine: Tears up plastic waste into small pieces for use with the other machines.

    Compression machine: Heats and mould presses plastic for the creation of large objects.
