Plastic is one of the most precious materials on earth. It’s lightweight, strong, easy to shape and great to recycle. But plastic is seen as a disposable and worthless material, it’s cheap, produced in enormous quantities and shipped all over the world. Of all the plastic we use just 10% is recycled. Mainly because the machines that produce plastic products are expensive, extremely complex and are used very efficient to keep costs low. Working with recycled plastic runs the risk of damaging or polluting machines, which might slow down the production process. But…
“Plastic can easily be recycled. It needs relative low temperatures and pressures. Look around and you’ll notice plastic waste is everywhere around us. We just need to sort it and have tools to turn it into new things.” Is the vision of Precious Plastic. Develop together Precious Plastic’s goal is to develop the ultimate plastic machinery together and share this open source online. They want that people all over the world can download the designs, build these machines and start a local plastic recycle centre. In these centres local plastic waste is collected, transformed into new products, and therefore making it possible to turn plastic waste locally into new products. Precious Plastic – The machines This project is a set of plastic machines, developed to set up a small scale plastic workshop. The machinery is based on general industrial techniques, but designed to build yourself. The machine is easy to use and made to work with recycled plastic. Whilst this entire project is still in development, the machines are shared open source online and improved by the community.
Extrusion Often used for extruding lines and pipes. The outcome of this process is a line of moulded plastic. The form depends on the shape of the nozzle. Making 3D printer filament with this is on the to-do list!

Rotational Mostly used to create large hollow objects. This machine is re-built of an old oven. It’s used to heat the mould inside. Whilst turning around, plastic sticks to the mould and forms the mould/object.

Injection Most of our plastic products are made with this technique, usually quick and extremely efficient. This machine is much slower and easier to use. It can still produce a product every couple of minutes and uses custom made moulds.
