| Author(s) | David, Katharina, Severin |
Precious Plastic is a project for DIY plastic recycling. More about the project on their website
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
- Sorting through the plastics recycling bin helps us reduce the amount of plastic trash
- Dumpster diving on the KQ?
Processing
Plastic Bags
Inspired by a video [1] and blogpost [2] of bjornsteinar.
- 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.
Small bag made out of recycled plastic bags
Small bag made out of bubblewrap
Further research necessary
- Styrofoam
- Disolvable in D-Limonene (Instructable)
Machines
Money spent so far (not really complete)
Shredder
Status: working!
- Hopper is falling apart, needs some glue
- Funnel from shredder into the collection box needs improvement
- Axis of the shredder might be a bit crooked
- More information on motors and how to start them: Drehstromasynchronmotoren, Starten von Motoren
- Electronics: Got a softstarter, missing a direction switch. But that's for later.
Compression
Status:
- Oven finished
- Need to build "Compression unit"
- To be combined with the extrusion machine
Injection
Status:
- Base: done
- Hopper: done.
- Missing the thread on the pipe, then it can be put together.
Other stuff:
- Some premade molds [7]
Extrusion
Status:
- Got the screw and pretty much most other parts
- Hopper already built
- Missing the motor
