Inauguration of the BIOSYNERGY biomass/SRF plant: SUEZ and Vauban Infrastructure Partners invest in decarbonised local energy production from waste

BIOSYNERGY is a pioneering energy recovery facility that addresses two of the Normandy region’s key aims: sending less waste to landfill and increasing production of renewable energy, in accordance with the targets of France’s Energy Transition for Green Growth Act (LTECV) .

The facility produces heat in the form of water vapour from 90,000 tonnes of non-recyclable waste, wood waste and SRF per year. The site will generate 300,000 MWh of energy per year, which will be fed into the Le Havre urban heating network – heating the equivalent of 24,000 homes – and will also be used by local manufacturers. Through that process, 50,000 tonnes of CO₂ will be avoided every year compared with burning fossil fuels, helping to decarbonise the region.

The project has benefited from a BCIAT (biomass heating for the manufacturing, agriculture and tertiary sectors) subsidy and financial support from the Normandy region.

By treating residual waste locally and converting it into energy, this infrastructure will enable the use of landfill to be reduced, while helping to meet the national target of carbon neutrality by 2050.

The solid recovered fuel (SRF) used in the BIOSYNERGY boiler is prepared locally at SUEZ’s TriNergy site in Rogerville, only a few kilometres from the plant.

The TriNergy unit is located at a former manufacturing site that has undergone remediation work and is a model for converting industrial land to serve the local circular economy. The TriNergy site takes in non-hazardous industrial and commercial waste, sorts it, removes the metal and shreds it, in order to produce high-quality SRF. Together with non-recyclable wood waste, that SRF is the fuel that powers the BIOSYNERGY plant.

BIOSYNERGY is an innovative project that is playing a strategically important role in the Normandy region’s environmental transition and boosting its economy, in accordance with the region’s sustainability policies. The project has attracted investment of €85 million, made possible by contributions from SUEZ and Vauban Infrastructure Partners (via its BTP Impact Local fund), subsidies from ADEME and the Normandy region, and the support of banks led by Caisse d’Epargne Normandie (CEN) and Caisse d’Epargne Ile-de-France (CEIDF).

The inauguration of the site was attended by:

• Hervé Morin, President of the Normandy Region
• Edouard Philippe, Mayor of Le Havre and President of the Le Havre Seine Métropole region
• Alban Bruneau, Mayor of Gonfreville-l’Orcher
• Guillaume Lefrançois, Deputy Regional Head of ADEME Normandie
• Sabrina Soussan, Chairman and CEO of SUEZ
• Mounir Corm, Founding Partner of Vauban Infrastructure Partners

This project represents a strong commitment to the circular economy, enabling the recovery of the region's residual waste. The BIOSYNERGY site is a model of territorial cooperation and mobilisation of local resources to meet environmental challenges while strengthening Normandy's energy sovereignty.
