Low-temperature chemical recycling of mixed plastic waste into renewable syngas for circular plastic production.

ReLab enables a truly circular plastics economy by converting mixed post-consumer plastic waste into high-value raw materials. Using an innovative Low Temperature Conversion (LTC) technology, the process transforms non-halogenated plastic waste into high-purity syngas (a mixture of hydrogen and carbon monoxide), which can then be used to produce methanol or virgin-quality plastic monomers.

Unlike mechanical recycling, which is limited by material quality and composition, the LTC technology operates at temperatures below 450°C, making it both energy-efficient and economically viable. Crucially, the process does not require sorting, allowing mixed plastic waste streams to be recycled that would otherwise be incinerated or sent to landfill.

ReLab addresses a major challenge in today’s plastic value chain: the majority of plastic waste cannot be mechanically recycled and is instead disposed of through incineration, generating CO₂ emissions and contributing to climate change. By enabling chemical recycling of a wider range of plastics, this solution reduces dependence on fossil feedstocks while producing materials of virgin quality suitable even for food packaging and medical applications.
By closing the loop on plastics that currently have no viable recycling pathway, the project supports emission reduction, resource efficiency, and the transition toward a scalable, circular plastics economy.
