Bricks made of Recycled Plastic

Nairobi-based startup company Gjenge Makers, founded by Nzambi Matee, has created a lightweight and low-cost building material that is made of recycled plastic with sand to make bricks that are stronger than concrete material. The company produces about 500-1000 bricks per day, and recycles close to 500 kilograms of plastic waste per day. Gjenge Makers’ project has started to use the product with paving stones applied in houses, schools or streets. The product is highly durable and diminishes maintenance costs.

Nzambi Matee, a 29-year-old trained engineer and schooled in biochemistry, founded new ways of converting waste into sustainable materials. With her initiative, Matee has recently been named a Young Champion of the Earth 2020 Africa winner at the United Nations Environment Programme (UNEP). The award “provides seed funding and mentorship to promising environmentalists as they tackle the world’s most pressing challenges.”
