In 2012, CEE undergraduate Sidhant Pai ’14 recognized a gap in the 3D filament market for a recycled filament offering. The idea turned into a project and since then has become a social enterprise that empowers Indian urban waste pickers with the technology to turn plastic waste into 3-D printer filament. The company, Protoprint, markets the filament globally and provides consumers with an ethically sourced, recycled alternative to virgin plastic. “I think the best way to empower a community is to make them a primary stakeholder in the model,” Pai said.
