We've got a lot of plastic trash all over Africa, especially in the cities. A team from IDDS (Amit Gandhi from the US, and Mark Driordan from the UK) decided to create a way to add value to waste plastic by using a low-cost process to transform it into something useful: plastic sheets. From these sheets can be made a number of other products. On display they had shoes, bags, pencil cases and folders.

The sheets can be made from 3ply to 40ply in thickness, and the cost of assembly is minimal.
