The Grandpuits advanced plastics recycling plant, located in Seine-et-Marne, started production in March 2026 and has an annual capacity to process 15,000 tons of plastic waste.
The Grandpuits plant transforms hard-to-recycle plastic waste from French households, including waste collected in yellow recycling bins, which is currently sent to landfill or incineration, into a synthetic oil through a pyrolysis process. This process involves heating the waste to high temperatures in an oxygen-free environment. It makes it possible to recycle waste that cannot be recycled mechanically and to produce circular petrochemical feedstock as a substitute for fossil feedstocks.
The synthetic oil contributes to producing recycled plastics of the same quality as virgin plastics, compatible with the strictest requirements, including food contact and medical applications. In 2023, TotalEnergies signed an agreement with two French partners, Citeo and Paprec, to secure the plant's long-term supply of plastic waste.
