Nzambi Matee operates a factory that makes brick out of plastic waste in Nairobi, Kenya.

"Our product is almost five to seven times stronger than concrete," said Matee, the founder of Gjenge Makers.

According to Matee, her company makes use of waste that cannot be recycled.

Gjenge Makers churn out 1,500 bricks each day, made from various kinds of plastic waste. 

The waste is made of high-density polyethylene, used in milk and shampoo bottles; low-density polyethylene, often used for bags for cereals or sandwiches; and polypropylene, used for ropes, flip-top lids and buckets. 

According to Matee, a material engineer, her factory has recycled 20 tonnes of waste plastic since she started in 2017.

Matee set up her factory after she ran out of patience waiting for the government to solve the problem of plastic pollution. She designed her machines.
