Press release overview

The Urban Community of Strasbourg has ambitious environmental goals. These goals involve a Climate Plan that exceeds the targets set by the Grenelle Environment Law for 2020 by 50%, which include reducing emissions of greenhouse gases, improving energy efficiency and using renewable energy sources.
One core aim of the strategy implemented to meet these aims is recycling household waste and wastewater as energy sources through anaerobic digestion, which means converting these resources into 'green' natural gas.

Biovalsan at the heart of this initiative

In line with the Urban Community of Strasbourg's aims, Biovalsan was initiated in 2011 as a result of collaborative efforts and proactive stance of three partners working in sustainable development: Lyonnaise des Eaux, Degrémont Services and Réseau GDS.

Biomethane: a green and renewable energy source

With a treatment capacity of 1,000,000 inhabitant equivalents, the Wantzenau Wastewater Treatment Plant (WWTP) is the fourth largest WWTP in France. The volume of biogas produced by this facility's digesters represents a potential energy generation capacity of 16 GWh/year, which is equivalent to the annual needs of 5,000 low-energy consumption homes. Biovalsan's purpose is to utilise this resource to benefit the Strasbourg community, based on a short, locally based processing model.

A project co-funded by the European Union

The technological, scientific and environmental value of Biovalsan was acknowledged by the European Commission, which included this project in its co-financing LIFE+ programme. In 2012 Biovalsan thus became a project with strong national and European visibility, attracting great interest and attention from public figures, the scientific community and the academic world.
