Plastic waste becomes 3D printing filaments

ProtoPrint is a brainchild of Sidhant Pai, a 21 year old in fourth year of his Engineering in MIT. Based in Pune (India), this startup has tied up with ragpickers who bring in the waste they collect to their site. Usually plastic was segregated from the waste at the dump site. The plastic was sold to scrap dealers but the ragpickers received a very small amount of money from it, often less that Rs. 50 per day.
At Protoprint’s site, the plastic collected is used for 3D printer filament production facilities at dump sites and this enables them to earn around 15 times of what they did with the same amount of plastic (News Item 3D Printing Materials Conference website, 4 December 2014).
