Scientists Have Made Concrete Using Plastic Waste

  • Using recycled plastic, they were able to get more than a 90 percent saving on CO2 emissions and fossil fuel usage compared to using the traditional steel mesh reinforcing.
  • The concrete was reinforced using recycled polypropylene plastic instead, and strength and durability tests show that the end result could be used to build footpaths and precast elements such as drainage pits and concrete sleepers.
  • Concrete is the second most-used material on Earth, second only to water, and production of cement, one of its key ingredients, is responsible for 5 percent of the world’s annual CO2 production.
