Recycled Plastic Bricks Stronger Than Concrete

Nzambi Matee is an entrepreneur with an incredible goal -- to turn plastic destined for the landfill into sustainable, strong building material. Her company, Gjenge Makers, uses the plastic waste of commercial facilities to create bricks that can withstand twice the weight threshold of concrete. Gjenge Makers is based in Nairobi, Kenya, where plastic waste pollution has become a severe problem. A study supported by the National Environmental Management Agency (NEMA) found that more than 50% of cattle near urban areas in Kenya had plastic in their stomachs. To combat this issue, the Kenyan government outlawed the use of plastic bags in 2017, and imposed a ban on all single-use plastic in protected natural areas last year. However, these bans only address the issue of consumer single-use plastic. Commercial waste is still a deep-seated problem within the country. The company offers pavers for residential and commercial uses. The heavy-duty 60 mm paver is strong enough to be used for parking lots and roads, while the 30 mm light-duty paver can be used for household patios and walkways. The light-duty paver is twice the strength of concrete and comes in a variety of colors. The factory is only in its beginning stages, but it has already recycled 20 tons of plastic since 2017 and created 120 jobs in Nairobi. In addition, Gjenge bricks are also one of the more affordable options on the market. They cost approximately $7.70 per square meter, as opposed to $98 per square yard for concrete produced in the U.S.
