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 and share them with interested people in the area. Maybe the CoMakingSpace becomes a bit of a [[recycling]] hub in the near future?

== Collecting/Preparing Waste ==
== Collecting/Preparing Waste ==
Something we can already do is collecting materials and sorting them for further use - starting with waste from the [[3D Printer Farm|3D printer farm]], for example. There would just need to be separate containers for [[PLA]], [[PETG]] and whatever else people are printing with, and some sort of clear signage alerting everyone of the importance to sort carefully.
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.


Mixed colors will give nice effects, but mixing different plastics might mess everything up due to their different melting points.
We have containers for...
* [[Material:HDPE|HDPE]]
* [[Material:PP|PP]]


* ''how to wash & dry?''
And would like to add...
* [[Material:PETG|PETG]] (3D printing waste)
* [[PLA]] (3D printing waste)
* [[Material:LDPE|LDPE]]


== Machines ==
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.

In order to dry your washed plastics, you can use the [[Spin Dryer|spin dryer]].


[[User:Armin|Armin]] got the laser cut parts and two [https://www.conrad.at/de/flanschlager-htb-grauguss-ucfl-204-bohrungs-o-20-mm-lochabstand-90-mm-197022.html flange bearings]; they are in a box in the [[Metal Workshop|metal workshop]].
=== Shredding ===
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|plastic shredder]] and add the shreds to the proper storage box (color AND material).

Materials Used: plastic waste


Precious Plastic is an international community working on plastics recycling. You can download their entire "kit" of documentation on various open-source machines here.

There are several members who are interested in building one or multiple of their machines and establishing recyling workflows (see InfoBox).

Goal

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?

Collecting/Preparing Waste

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.

Washing

The easiest way to wash freshly emptied food containers etc. is to stick them into your dishwasher. Caution: PET may already deform at some programs' high temperatures!

To try: how to wash larger amounts at the Space?

In order to dry your washed plastics, you can use the spin dryer.

Shredding

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 ;-)

Offline

At the Space:
Massi and Martin are going to print/laminate some of the posters from the Precious Plastic community to inform about the project in general (perhaps in the common room, along with some of our own photos) as well as specific facts and techniques (in the Precious Plastic area).

Collection points:
[Later]
We could think about asking 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.

Machines

Besides specially built machines, we may also be able to use some existing ones for plastic recycling experiments:

Rotomolder

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!
