De Amerikaanse start-up 3D Brooklyn gebruikt plastic korrels afkomstig uit weggegooide chipszakken om filament, een grondstof voor 3D-printers, te produceren. Chipszakken bestaan uit een meerlaagse folieverpakking met een mengsel van polypropyleen en polyethyleen, samen met een dun laagje aluminium aan de binnenkant van de verpakking. Volgens verpakkingsdeskundigen zijn chipszakken moeilijk te recyclen, maar is het laagje opgedampt aluminium nodig om smaakafwijkingen door uv-licht, vocht en zuurstof tegen te gaan. De firma 3D Brooklyn ziet toch mogelijkheden voor recycling van chipszakken door er filament, het kunststof waarmee veel 3D-printers objecten opbouwen, van te maken. Dat doen zij op basis van plastic korrels, pellets, die het bedrijf TerraCycle, actief in upcycling en recycling, kan maken uit weggegooide chipsverpakkingen. De pellets worden door 3D Brooklyn omgesmolten tot bruikbaar filament. Een rol filament op basis van oude chipszakken met een gewicht van 450 gram bevat circa 45 hergebruikte chipszakken. Het grijskleurige 3D-printmateriaal smelt optimaal bij een temperatuur van 210 graden Celsius. De netto CO2-voetafdruk van een rol bedraagt 1,6 kilogram. Een rol kost $ 24. Meerdere bronnen voor maken van filament 3D Broolyn zegt nog op zoek te zijn naar andere restmaterialen die zich goed lenen voor recycling tot filament. Eerder ontwikkelden bedrijven filament op basis van schillen van koffiebonen, petflessen en dashboards. Daarnaast is er ook hardware op de markt om zelf filament te maken op basis van afgedankte 3D-objecten en afvalplastics.

Does 3D printing have promise for reinventing manufacturing, as well as some other specialized tasks? Yes… but, for now, it still strikes me as a way to produce tchotchkes, knick-knacks, and trinkets (the word the Christian Science Monitor chose). But if the plastic that goes into those items comes from plastic that’s been recovered for recycling, that’s not a bad thing – right? Sure: obviously, there’s a demand for those tchotchkes, knick-knacks, and trinkets, so if we’re going to 3D print these things, why not do it from waste plastic? We’ve seen a number of efforts along these lines already; the latest effort comes from Brooklyn-based design firm 3D Brooklyn. After making the connection by looking at take-out containers they were throwing away, the company connected with Terracycle, the New Jersey-based company that figures out how to reuse materials that can’t be traditionally recycled. The answer: potato chip bags. No, not the potato chip bag you toss in the trash: I’d guess the necessary cleaning on those might make them too expensive. But Terracycle has a ton of post-industrial bags that needed to be put to use; using them to print 3D items seemed like a good fit.

39-årige Trine Ojen har for nylig fået placeret en indsamlingsplads for Tassimo-kapsler ved den lokale Super Brugs i et samarbejde med butikken. Og indsamlingspladsen for kaffekapslerne er kun en lille del af den genbrugstanke, der fylder meget i Trines liv. Således ryger tøj, legetøj og nips til Kirkens Genbrug, mens ting som æggebakker og syltetøjsglas ryger op på den lokale friskole, der kan få glæde af det til blandt andet lysestager og projekter. Genbrugstendensen er ikke noget Trine Ojen selv er vokset op med, men det er en tanke, der er kommet til hende gradvist. "Det er jo nok en livsstil. Jeg synes, det er vigtigt, at jeg leverer den samme planet videre til mine børn, som jeg selv bor på. Så det miljømæssige spiller en rigtig stor rolle", siger den 39-årige bogholder.

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.

Entre as 11 selecionadas, está a TerraCycle, líder global em soluções de materiais de difícil reciclabilidade. Criada em 2001 nos EUA pelo calouro universitário Tom Szaky, a empresa é hoje responsável por desviar, mensalmente, cerca de 2 mil toneladas de resíduos de lixões e aterros...

CLINTON – The Hunterdon Art Museum is working to conserve the environment by recycling foil-lined wrappers in TerraCycle’s Energy Bar Wrapper Brigade, sponsored by Larabar energy bars. Despite being new to the program, the museum is one of the top collectors of 2015, having recycled more than 4,800 wrappers since signing up earlier this year. “I personally try to live a low waste lifestyle at home and was very happy to bring that effort to my work place,” said Jennifer Brazel, director of education at Hunterdon Art Museum. “As an art school, we generate a lot of waste. Our staff eats a lot of Larabars and other foil-lined on-the-go bars due to our busy schedules and our summer camp students bringing snacks daily. “I really appreciate that TerraCycle makes the entire recycling process easy, plus the points program makes recycling a very appealing as a fundraiser for our nonprofit organization.” Through the recycling Brigade programs from TerraCycle, collectors can earn points that can be redeemed as a donation to a nonprofit organization of their choice. The Hunterdon Art Museum has chosen to fund their education programs as well as donate to Charity:Water, an organization that brings clean and safe drinking water to people in developing countries. “Everyone can recycle,” Brazel said. “It’s the most simple, efficient and cost effective way each person can reduce waste and play a role in increasing sustainability. Recycling cuts material costs, making recycled items less expensive than virgin material items. Plus, who wouldn’t want a cleaner environment? Recycling is a no-brainer.” Any school, organization or individual looking to reduce waste can find more information on TerraCycle and the Energy Bar Wrapper Brigade sponsored by Larabar at www.TerraCycle.com.”

A 3D printing company sells trinkets made from plastic bags, such as the ones that typically contain potato chips, that can't normally be recycled.

While it's incredibly exciting that 3D printing is a technology that has the potential to change the face of many familiar industries, it's alarming to think that most printer filaments are made from non-recycled plastics. Fortunately there are now several companies that are taking inventive approaches to 3D printing filaments by recycling automotive dashboards or using water-soluble materials that can be used in additive manufacturing. 3D Brooklyn is a company that's also approaching 3D printing from a perspective that fuses sustainability and creativity—its printer filament is made from recycled potato chip bags. The Recycled Potato Chip Bag Filament is a blend of polypropylene and polyethylene that is reported to have the same texture as wicker furniture. The unique 3D printing filament was created in collaboration with TerraCycle, a company that partners with brands on projects that involves repurposing waste.

Potato chips are a guilty pleasure for a lot of people. I hardly ever buy them, in keeping with my philosophy of “if you eat healthy at home, you can eat terribly elsewhere.” I tend to attack them at parties, though. No matter how frequently you buy or eat them, potato chips are everywhere, along with their weird, shiny, crinkly packaging. Is it plastic? Is it foil? It is plastic, but it’s an odd hybrid of polypropylene and polyethylene that makes up those metallic pouches capable of blinding you if the sun hits them a certain way. Unlike most plastics, potato chip bags’ blended plastic properties make them unfit for recycling – that’s a lot of greasy shiny material going to the landfills. Unfortunately, there are a lot of disposable products that are unfit for recycling, and that’s why companies like TerraCycleexist. The New Jersey company collects nonrecyclable or hard to recycle waste and figures out ways to recycle or repurpose it. They were the first resource that came to mind for Will Haude, founder of 3D Brooklyn, when he began to feel bothered by the amount of plastic waste his company generated. He wondered why his company, which manufactures custom 3D printed items from electronic accessories to planters, couldn’t start reducing rather than generating plastic waste.
