When 3D printing and design studio 3D Brooklyn got overwhelmed by the plastic waste the company generated within a short period of time, founder Will Haude wanted to take action and reduce some of that waste by using recycled materials. Haude turned to New Jersey-basedTerraCycle, a company that among other projects for waste that isn’t fully recyclable, turns used potatoes chip bags into pellets. The bags are made of a PP/PE (polypropylene/polyethylene) blend, that can’t be recycled as the individual materials and therefor doesn’t find many applications for re-use. TerraCylce first cleans the bags, before they are shredded and turned into pellets. 3D Brookly then uses these pellets to extrude them into 3D printer filament. The 0.45 kg spool is made of 45 recycled bags and available in 1.75 mm diameter.
