Gjenge Makers, a factory in Nairobi, Kenya, takes plastic waste and turns it into a brick that is five to seven times stronger than concrete.
Nzambi Matee hurls a brick-hard against a school footpath constructed from bricks made of recycled plastic that her factory turns out in the Kenyan capital.
It makes a loud bang but does not crack. ”Our product is almost five to seven times stronger than concrete,” said Matee, the founder of Nairobi-based Gjenge Makers, which transforms plastic waste into durable building materials.
“There is that waste they cannot process anymore; they cannot recycle. That is what we get,” Matee said, strolling past sacks of plastic waste. Matee gets the waste from packaging factories for free, although she pays for the plastic she gets from other recyclers. Her factory produces 1,500 bricks each day, made from a mix of different kinds of plastic.
