Indian Company Protoprint Transforms Waste into 3D Printing Filament for Commercial Use. 3DPrint.com, November 10, 2016.

Protoprint’s 3D filament in use
This week, we reported on New Zealand-based Waikato University’s revolutionary FDM technology-based 3D printing method that allows anyone to print complex objects by converting waste material into thermoplastic filament, and we’ve seen several initiatives around the world focused on bringing waste material into reuse via 3D printing. An Indian company called Protoprint is leading a similar project but on a more commercial aspect and global scale.
Protoprint, a social enterprise founded by environmental engineer Sidhant Pai and his parents in 2012 to address poor employment conditions and increasing pollution levels, secured a partnership with SWaCH to transform high-density polyethylene (HDPE)-based products such as plastic bottles into filament for 3D printers.
SWaCH, short for Solid Waste Collection and Handling, is a cooperative formed by waste pickers and workers at a waste disposal site in Pune, India. Workers at SWaCH provide Protoprint with the necessary waste material which Pai and his team use to create filaments.
