* Material: plastic bags or bubble wrap
* Tools: iron and baking paper
* Steps
** Place material between two sheets of baking paper.
** Iron single sheets as the shrinking is quite drastic and not really predictable (if material ruptures or holes are forming, try reducing the temperature).
** Fuse pre-ironed sheets together to create thicker, stronger material or extend the material dimensions.
** Optionally imprint their textures to the surface by using fabrics or perforated metal plates.

Precious Plastic is a project for DIY plastic recycling. David and Severin have started been building a plastic recycling workshop in our lab, and here you can find a bunch of information on it. More about the worldwide project on their website.

You think this idea is super awesome? You can be a part of it! Here's how:

Collect Plastic

The easiest way to help out is to collect plastic. Most of us still use a lot of single use plastic at home. Let's put it to some good use.

The Elevator Pitch

Collect these three things:

  • Joghurt Cups (also Cream, Custard, .., these plastic things with usually a foil lid on top)
  • Shampoo Bottles
  • Cream Cheese Containers

Make sure they're clean (you can usually simply throw them in the dishwasher alongside your other dishes), and bring them to our workshop for shredding and recycling.

Get others to collect plastic

  • Ask your local Döner place or other restaurant about what they do with plastics. They usually get some of their ingredients in big plastic buckets.
  • Get your neighbors involved

Gather Tools and Machine parts

We still need a few things for our workshop. If you or someone you know might have access to any of this, and could donate it to us, that would be amazing. Here's our current list:

  • Motors
    • Motor for the extrusion machine
      • Speed between 50 and 100 rpm
      • around 0.75 kW power
    • Replacement motor for the shredder
      • Speed between 50 and 120 rpm
      • Torque around 200 to 350 Nm
      • Motors with these speeds should have a power rating around 2 kW to have enough torque
  • T-Shirt Press
  • VFD (Variable Frequency Drive) for the extrusion motor

Join our Meetup & our Workshop

We have started our monthly meetup series. Check the Meetup page for the next date.

Building these machines and keeping them running costs time and money. So does getting them to events and shows. You can send us a donation via PayPal by mentioning Precious Plastic in the message.

Next Steps

What are our plans for the (very) near future?

  • Finish our injection molding machine ✅
  • Make some molds and inject some cool parts
  • Get a mold for the compression machine
  • Have a booth at Make Munich 2019 and show some stuff to the world ✅
  • Get our own workshop

Collecting

We're collecting different types of plastic in labeled black boxes ( + one box for the stuff we're not sure about). Everything should be clean before it gets into the boxes!

  • Acrylic is really hard to recycle apparently, so we're not collecting that
  • PVC can currently not be recycled.
  • Bubblewrap is apparently really cool.
