Pyrowave’s patented microwave-based platform brings an immediate answer to the global challenge of plastic waste by equipping progressive partners with a scalable electric solution that regenerates plastic products to infinity. We pave the way to a true circular economy of plastics.

Our PW6 modular technology platform allows the electrification of the material, a new way to restore our products and materials in an environmentally-friendly way. Our equipment processes polystyrene. With quick and easy deployment, it is possible to increase sorting and processing capacity according to local plastic waste volumes.

Main characteristics

Our PW6 modular technology platform is a unique piece of equipment that uses microwaves to recycle PS over and over again.

  • Styrene monomer purity similar to virgin up to 99.8%.
  • 1,000 tons/year of recycled plastics per reactor.
  • An unmatched liquid yield of nearly 98%, the highest in the industry.
  • 5 to 7 times less GHG emissions compared to virgin styrene production.
  • 15 times less energy to manufacture styrene monomer from virgin resources.
  • Pyrowave licenses its process and sells equipment and services related to its unique microwave reactor.

From dead ends to endless

Pyrowave’s patented microwave catalytic depolymerization technology provides the most advanced high-power microwave technology worldwide, now at the forefront of a new revolution designed to increase resource efficiency.

The PW6 reactor and sublicensed process for the production of recycled styrene is specifically designed for polystyrene (PS) raw materials and can process the full range of expanded polystyrene (EPS) and high impact polystyrene (HIPS).

  • 1/ The continuous process heats and liquefies the plastic in a preparation vessel equipped with a filter that removes inorganic contaminants such as labels and films, in addition to other impurities. This also helps inject plastics into the reactor more easily.
  • 2/

    The processed polystyrene is introduced into the reactor where it is mixed with silicon carbide particles to interact with a high energy microwave field.

  • 3/

    Using electrical power and microwaves, the developed process breaks down polymer chains into monomers (depolymerization). At this stage, organic contaminants and colour pigments are removed through the intense microwave heat.

  • 4/

    Post-consumer polystyrene is thus converted into a liquid rich in blocks – the monomers – which are then purified and meet the same specifications as the monomers used in the industry.

  • 5/

    These purified and recycled blocks are then reprocessed by a manufacturer and restored into virgin resins, to manufacture a variety of products such as polystyrene, synthetic rubber, latex and plastics for electronic products.

    Therefore, new products and packaging can be manufactured from 100% recycled polystyrene.

Recycled materials by PW6

Molecular recycling allows styrene to be recycled over and over again. By returning styrene to the state of molecules identical to virgin molecules, molecular recycling allows access to the same markets as virgin resins and thus creates a new generation of plastics!
