Superior Technology

From Waste Plastic to High-Value Concrete Product

Using thermo-mechanical extrusion technology, the Plazrok process converts unrecyclable waste plastic bound for landfills into a concrete additive and partial replacement for stone aggregate.

Plazrok has many advantages over traditional concrete aggregate

Plazrok USA is developing an additive for concrete made from waste plastic that makes concrete lighter but just as strong—concrete made with Plazrok has flexural and tensile strength that is comparable to traditional lightweight concrete.

Plazrok advantages over standard aggregate:

  • Has an average 1:5 ratio of weight for equal volumes (Plazrok versus standard coarse aggregate)
  • 100 kg of Plazrok is volumetrically equivalent to 500 kg of standard concrete
  • Meets specifications for tensile and flexural strength
  • Has enhanced acoustic properties
  • Is easier to manage than porous pre-moistened rock
  • Saves time by shortening release time from prestressed forms
