Plastics Recycling: TotalEnergies Becomes the...

(LSE:TTE) TotalEnergies agreed to acquire Plastic Energy’s 35% interest in the Grandpuits advanced recycling plant, in which TotalEnergies already held a 65% interest. The Grandpuits advanced plastics recycling plant, located in Seine-et-Marne, is now wholly owned by TotalEnergies. The plant 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, into a synthetic oil through a pyrolysis process. This process enables the recycling of waste that cannot be recycled mechanically and produces 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 Citeo and Paprec to secure the plant’s long-term supply of plastic waste.

Exploration in Angola: TotalEnergies Announce...

(LSE:TTE) TotalEnergies announced several exploration successes at the Angola Oil & Gas Conference, including the Acacia-5 near-by discovery on Block 17, where TotalEnergies holds a 38% operated interest. First Oil from Acacia-5 will be achieved only three months after the discovery made in June 2026, through a fast-track development leveraging the available capacity on the Pazflor FPSO.
