Description DIY Plastic Recycling
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

Material Samples (left:2 layer bubble wrap, right:8 layer 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.

Further research necessary

  • Styrofoam
    • Mostly polystyrene, "expanded polystyrene", short EPS
    • Dissolvable in Acetone (but that's kinda nasty and not exactly healthy
    • Topics in the forum: [3] [4]
    • Maybe heat and compression to make it smaller and shreddable?

Machines

Money spent so far (not really complete)

Shredder

Status:

  • Shredding unit: Completed
  • Motor: Available
  • Electronics: Got a softstarter, missing a direction switch. But that's for later.
  • Missing:
    • Chain and gear to connect the motor to the shredding unit
    • Table to put it all together

Compression

Status:

  • Oven finished
  • Need to build "Compression unit"
    • To be combined with the extrusion machine
    • Missing the car jack

Injection

Status:

  • Base: Almost done
  • Hopper: done.
  • Missing some steel bars (30x4)
  • Missing thread cutter

Extrusion

Status:

  • Got the screw and pretty much most other parts
  • Hopper already built
  • Missing the motor
