There are several members who are interested in building one or multiple of their machines and establishing recyling workflows (see InfoBox).
Plastics are very versatile materials, but are mostly made from non-renewable sources and can persist in the environment for very long times after their (often short) intended life cycle.
Naturally, many people concerned with sustainability have tried to come up with ways to reuse, repurpose and recycle "waste" plastics and we want to join them! As a community workshop, we can build machines that individuals might not be able to accomodate and share them with interested people in the area. Maybe the CoMakingSpace becomes a bit of a recycling hub in the near future?
We collect clean plastics, sorted by type, in the Precious Plastic Area. A more detailed sorting system (color) for the raw material would probably take up too much space.
We have containers for...
And would like to add...
There should be some sort of clear signage alerting everyone of the importance to sort carefully! Mixing different plastics might mess up the products later on due to their different melting points.
- how to wash?
In order to dry your washed plastics, you can use the Spin Dryer
Mixed colors will give nice effects in the final pieces, but for everyone to stay in control over their colors we should only collect shreds of similar color! If you shred more than you use right away (probably the usual procedure), please throw only matching pieces into the plastic shredder and add the shreds to the proper storage box (color AND material).
Promoting the Project
This is a project that aims to change the world, so we need to reach a few people ;-)
- Flor started a facebook page and instagram account
- Armin will work on a website and a customized "Precious Plastic Heidelberg" logo
- Lukas maintains two pins on the Precious Plastic map
- "machine builder" CoMakingSpace
- "workspace" Precious Plastic Heidelberg
not started yet
We want to ask supermarkets whether we can put up collection boxes for bottle caps next to their Pfandautomaten - along with the box, there should also be some kind of information (flyers to take?). The collection box design should be easy to recreate when we need more, e.g. made with the CNC router.
Besides specially built machines, we may also be able to use some existing ones for plastic recycling experiments:
- drying ovens - e.g. to melt plastic bags
- Spin Dryer
- heat gun
- hot air soldering station
- what else can you think of?
Plastic needs to be cut into manageable pieces before it can be recycled - therefore, the shredder was the first machine we built!
...to be built once the shredder is finished
...perhaps to be built once the injection molding machine is finished
...we're probably not going to build this one anytime soon but will rather try using weights and a drying oven
Not part of the precious plastic portfolio - could be made from an old cement mixer, just needs some add-ons for temperature control, a timer and some way to automatically rotate the handwheel (Flor has some experience with it). Another (smaller option) could be the open source "ROTOCASTit" machine.
You can make cool hollow shapes with a rotomolder, e.g. lamps like these!
