Story details
TotalEnergies agreed to acquire Plastic Energy’s 35% interest in the Grandpuits advanced plastics recycling plant in France. The company already owned 65% of the facility and said in its September 11 announcement that it now owns the plant outright. The deal accompanies Plastic Energy’s ownership restructuring. TotalEnergies did not disclose a purchase price or the conditions for closing the deal.
The plant is in the Seine-et-Marne department and began production in March 2026. It has the capacity to process 15,000 tonnes of plastic waste a year. Its feedstock includes hard-to-recycle household plastics collected in France, including material placed in yellow recycling bins. TotalEnergies says such waste is currently sent to landfill or incineration. The facility is intended to redirect part of that stream into a feedstock that can be used again by the petrochemical industry.
The process uses pyrolysis: plastic waste is heated to high temperatures in an oxygen-free environment and converted into synthetic oil. TotalEnergies describes the oil as circular petrochemical feedstock that can substitute for fossil-based inputs. The company says processing it can yield recycled plastics with the same quality as virgin plastics, compatible with stringent requirements that include food contact and medical applications. The announcement describes the process and intended uses; it does not publish plant-specific output or product certification results.
In 2023, TotalEnergies signed an agreement with French partners Citeo and Paprec to secure long-term supplies of plastic waste for the plant. That arrangement links the facility to local collection and recycling channels. The change to sole ownership does not itself alter the plant’s processing capacity or technology. The release announced no capacity increase, additional production unit or expansion schedule. Production that began in March and the stated 15,000-tonne annual capacity remain the measures of the facility’s disclosed scale.
September brings an ownership change rather than a new plant opening. The pyrolysis facility is designed to route plastics unsuitable for mechanical recycling into a different feedstock stream. Its environmental and commercial performance can be assessed through operating data such as the waste actually processed, synthetic-oil yield and sale of resulting products.
