She Turned Plastic Into Bricks

This girl from Kenya left the whole world speechless. She makes bricks out of plastic waste, and not the easy to recycle kind, but the plastic that even recycling centers refuse to take. She mixes it with sand, pressing bricks reportedly five times stronger than concrete. They weigh almost half as much, are waterproof and cost significantly less than conventional building materials. Her name is Inzimbi Matisi, a materials engineer from Nairobi who saw in plastic not just a problem, but a free raw material. She left the oil industry, experimented for a year with mixes and built the production machines herself. Today, her factory produces around 1500 bricks a day with demand much higher.
