Amazing idea. Waste mountains are a growing issue in many developing countries. Reflow, a Dutch company, has created a process to turn plastic waste into ethical filament for 3D printing. Place this in, say, Tanzania where shanty towns spring up around waste with poorly paid waste pickers, and a virtuous cycle is created where pickers are better paid to find plastic that can be recycled into ethical filament, the waste mountains reduce, demand for imported material for filament goes down, and local industry is stimulated. Tremendous idea. Support their kickstarter campaign to get it going here https://www.kickstarter.com/projects/reflow/reflow-recycled-pet-filament-made-in-developing-re
