A major new wastewater treatment facility has opened in the coastal town of Sète, France.
The Eaux Blanches plant, inaugurated on 14 June is designed to manage growing wastewater needs and act as a flagship project in the use of biomethane as a clean energy source.
With an investment of more than €64 million, the project was led by Sète agglopôle méditerranée, the Rhône Méditerranée Corse Water Agency, and Thau Maritima — a partnership between SUEZ and infrastructure investor Vauban.
One of the plant’s standout features is its ability to recover and transform organic waste into renewable energy, according to SUEZ.
Each year, it produces around 500,000 cubic metres of biomethane — derived from the breakdown of sewage sludge.
This energy is fed back into the national gas grid via the GRDF network, helping reduce dependence on fossil fuels and lowering carbon emissions.
