Kenyan recycles plastic waste into bricks stronger than concrete
  • Using plastic waste that can’t be recycled, Kenyan materials engineer Nzambi Matee makes bricks that are 5-7 times stronger than concrete.
  • They’re made from plastic combined with sand, and the most popular grey bricks cost $7.70 per square metre.
  • Matee designed her own machines and started a factory in 2017, recycling 20 tons of plastic since then.
  • She started it because of the local government’s inability to deal with the plastic pollution problem.
