Cat-HTR™ Chemical Recycling – The New Plastics Revolution

Licella and BioLogiQ join forces to accelerate commercialization of Cat-HTR™ technology in Australia, to chemically recycle post-consumption plastic that would otherwise not be recycled

Chemical recycling with Licella’s Catalytic Hydrothermal Reactor (Cat-HTR™) technology is the new plastics revolution. Cat-HTR™ enables any mix of post consumption plastics to be converted back to oil. Instead of being sent to the landfill, plastics can be used to make new plastics, a truly circular solution for post-consumer plastic.

Chemical recycling with the Cat-HTR™ technology plays an essential role in transitioning to a circular economy for plastics, helping to close the loop by recycling previously non-recyclable plastics. The Cat-HTR™ technology can recycle a blend of End-of-Life Plastics that include polypropylene, polystyrene, soft plastics (low density PE) and multilayer flexible plastic packaging. Cat-HTR™ is a highly efficient process that produces a high yield of oil from plastic (around 85% oil, with the balance as gas that can be recycled to power the process). For waste plastic, the products created from the Cat-HTR™ process are estimated to produce 2-3 times more value than Waste to Energy (incineration) with half the emissions.

Cat-HTR™ Chemical Recycling: Beyond Mechanical Recycling

Cat-HTR™ chemical recycling tackles all plastics that can’t be processed in mechanical recycling systems. Cat-HTR™ opens the door for food-grade multilayer plastics to be converted into oil that can be converted once again into food-grade multilayer packaging.

Mechanical recycling has a proven track record in polyethylene terephthalate (PET) beverage bottles, high-density polyethylene containers like milk jugs, and protective films, like intercompany stretch wraps. The industry is working to improve the recyclability of flexible films, but beyond that, the quality would be so limited.

That’s why only about 9% of plastics get recycled in the United States (15% in Europe). Only 2% of recycled plastic is turned into new plastic products.

Today, Plastic Packaging Material flows are largely linear


Cat-HTR™ chemical recycling converts any kind of waste plastics into oil and gas that can be used to create new plastic products, including food-grade containers. Instead of plastic made from fossil fuels, it’s made from waste plastic—completing the circular economy for plastics.

Cat-HTR™ provides the technology to transition from recycling 2% of plastics to perhaps recycling 80% of plastics into new usable products.

Why BioLogiQ is Partnering with Licella

Licella and BioLogiQ have a shared vision for a more sustainable future. Being able to generate cash from waste plastics incentivizes collection, hopefully preventing plastic from leaking into the natural environment and reducing the need for fossil oil, while significantly reducing carbon emissions. Further reductions are achieved by using BioLogiQ’s NuPlastiQ, a 100% plant-based biopolymer made from annually renewable potato starch.

BioLogiQ believes Licella’s Cat-HTR™ is the best technology to convert mixed plastics into valuable oil and gas. Enabling the transformation of “worthless” mixed plastics into “valuable” oil and gas can significantly reduce the amount of plastic that ends up in landfills or leaked into the environment.

Central to the Licella and BioLogiQ partnership is the global commercialization of the Cat-HTR™ technology. BioLogiQ invested in Licella to accelerate the construction of a 20,000 ton per year facility in Australia. By accelerating the Cat-HTR™solution, this alliance is helping the world deal with the plastic pollution problem. 


Licella has spent the past 12 years developing its proprietary hydrothermal upgrading platform, the Cat-HTR™. The technology has been extensively tested over a range of renewable biomass and End-of-Life Plastic feedstocks at Licella’s large-scale continuous-flow pilot plant on the Central Coast, an hour north of Sydney, Australia. The synthetic oil from the Cat-HTR™ process can be refined into chemicals to produce new plastics, used to produce more sustainable fuels and waxes, and has applications including road base and low sulfur marine fuels. With over AU$75M invested in the Cat- HTR™ platform, it is now commercial-ready.

Licella is working with its strategic partners to build the world’s first commercial-scale hydrothermal upgrading plants. The Cat-HTR™ platform can be fully integrated within partner’s existing infrastructure, to provide a brand-new revenue stream to industries such as pulp and paper and resource recovery. By doing so, Licella is helping to provide a high value proposition for its partner’s low value residues, diverting plastic from landfill, incineration and the natural environment and reducing reliance on virgin fossil crude.
