Keeping resources in continuous use by recycling and
regenerating materials, for a circular plastics economy
The process begins with plastic preparation. End-of-life plastic is shredded and unwanted contaminants such as glass, metals, grit and stones are removed. An advantage of the Cat-HTR™ is that plastic need not be dried in advance of the process. The shredded plastic is then heated and compressed, combined with supercritical water and further heated. It then enters the Cat-HTR™ where the water acts as ‘molecular scissors’ to break down the polymeric bonds, donating hydrogen to create useful short-chain, stable hydrocarbons, which are separated and stored.

A Circular Economy: moving away from plastic consumption and disposal to
recovery, regeneration and re-use, for a zero-waste model
A circular plastics economy is a sustainable alternative to the traditional linear model of create-consume-dispose: keeping plastic in use for as long as possible, recovering and recycling it to extract value and regenerate it into new products, creating a make-consume-recycle model. This model eliminates waste plastic leakage into the environment and reduces the requirement for fossil feedstock in plastic production.
Our technology offers a solution as part of a circular economy model. By processing plastics which are not currently recycled due to limitations in mechanical recycling techniques, we can help improve on the scope of materials which can be recycled. Furthermore, there are no limits to the number of times plastic materials can be re-processed with Cat-HTR™, unlike currently available conventional mechanical recycling methods.
