Stuff4Life is collaborating on REHIP - the Research England Hydrogen Innovation Project - to develop pyrolysis options for residual materials with high fossil carbon content which can be used to generate ‘turquoise’ hydrogen.

REHIP is a four year, £11m collaboration between Teesside University and Durham University, with a range of industry partners including Stuff4Life. Its primary goal is to accelerate the development and adoption of hydrogen technologies in the Tees Valley region to help achieve a net zero economy.

Hydrogen is a building block of chemicals and compounds including plastics, as well as being used as a fuel in place of natural gas. Waste HDPE and LDPE are excellent feedstock materials, producing up to 65% turquoise hydrogen by volume in our testing.

Turquoise hydrogen is made using a process called pyrolysis, producing hydrogen and solid carbon. It is considered a low-emission process. The solid carbon can be used in products, which we are also exploring.

We are now developing a process solution for dedicated, clean end of life material inputs which we will be scaling up in 2026. This work comes at an important time for industry, with mechanical recycling of plastics under intense pressure due in part to low market values, and at a time when incineration plants want to reduce fossil carbon inputs due to the impending impact of the UK Emissions Trading Scheme, which will be expanded to cover incineration in 2027.

We want to talk to anyone interested in processing clean streams of LDPE or HDPE, or in utilising turquoise hydrogen as a feedstock or fuel.
