Our mission is to turn your waste into new filament, which will then be available for sale. If you register we will keep track of your donations and you’ll get points that can be redeemed in our store. We’re perfecting the process now using your donations, so keep them coming and check back for updates

Start saving your PLA waste and empty spools. Register and note your ID number. When you have a good collection, write that number in or on the box and mail it to us, or drop it off at our Ann Arbor, Michigan location.

There are many variants of PLA and it’s impossible to know exactly what’s in them, but in general, anything with PLA in the name is fine (PLA+, glossy, matte, silk, any color). However, we want to avoid additives like wood, carbon fiber or glow-in-the-dark material. If you’re not sure, just contact us first to ask, or leave a note in the container to let us know what’s there.

Yes, we want to reuse those spools too!

No, you can send as much or as little as you have, but fewer shipments are better for everyone.

Nope, just write your RS-#### number somewhere if you want credit.

There’s no need to sort by color or brand. We can take any shape or size of waste, from huge prints to color change poops, or unwanted filament still on the spool. Just make sure it’s free of any foreign materials like paint, glue, etc., and please make sure it’s PLA only.

Not at this time. To keep things as efficient as possible, we need to pool together lots of waste and process it in large batches. This way, you get to be part of a team effort to reduce plastic waste. You can even see which batches of filament your waste went into, and see your fellow contributors, on your account page.
