Cat-HTR converts end-of-life plastic waste into stable products that can be used as feedstocks in the petrochemical industry


Our process achieves in just 25 minutes what takes nature 200 million years, turning plastic waste into readily usable hydrocarbon feedstocks.

The Cat-HTR technology was originally developed by Australian company, Licella Pty Ltd (Licella), in partnership with the University of Sydney. Initially used to process non-food biomass to produce biocrude oil, the technology was found to be suitable for processing a range of feedstocks. Most importantly for ReNew ELP, this included a range of plastic compounds confirming the technology as suitable to recycle end-of-life plastic waste.

The Cat-HTR utilises water in the supercritical state. In this state the water breaks down the polymeric structure of the plastic feedstock and hydrogen is harvested from the water for use in the creation of new, stable hydrocarbon molecules.

ReNew ELP’s technology will contribute to the expansion of the circular economy for plastic by diverting the waste from incineration and energy from waste plants.  The products can be used to replace conventional fossil derived refinery feedstocks reducing the generation of greenhouse gases and unwanted by-products (flue gas emissions).

Hydrothermal upgrading produces a stable product, which can be easily shipped, is not acidic and is miscible (blendable) with conventional refinery feedstock.

Advantages of our chemical recycling process:

  • High conversion efficiency
  • Scaleable due to improved heat transfer
  • Does not suffer from generation of toxic by-products such as dioxins
  • Higher yields than other thermal conversion technologies
  • Controllable reactions and process flexibility
  • Stable products
