Chemical Recycling – The Solution to the Plastic Problem

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 means End-of-Life Plastics, which would otherwise be sent to landfill, can be converted back to the chemicals they originally came from. These chemicals can then 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, without the need to sort plastics into a single stream. 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 that Waste to Energy (incineration) with half the emissions.

Licella and BioLogiQ have a shared vision for a more sustainable future. A circular recycling solution for plastics prevents plastic from leaking into the natural environment and reduces 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.

Central to the Licella and BioLogiQ partnership is the global commercialization of the Cat-HTR™ technology. By accelerating the Cat-HTR™ solution globally, this alliance is helping the world deal with the estimated 111 million metric tons of plastic waste that will be displaced by the Chinese import ban by 2030.

About Licella
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 to 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.
