Recycling wastewater treatment plant sludge – a step toward green energy at the local level

Biovalsan is a pilot project for converting biogas produced from the Urban Community of Strasbourg’s wastewater into biomethane. This biomethane will be injected into the gas network of Réseau GDS, becoming a new source of environmentally friendly and renewable energy.

Biovalsan is supported by the European Union’s LIFE+ programme

Through this support, the project will expedite progress of the entire biogas industry. This funding will be largely used to study and analyse the biomethane produced, thereby promoting overall scientific knowledge in this field. In exchange for funding provided through the LIFE+ programme, the European Union has imposed clear guidelines for Biovalsan, including conducting analyses and regular progress reporting.

The project leader of Biovalsan vis-à-vis the European Union is Lyonnaise des Eaux, together with its partners Degrémont Services, Réseau GDS, and the Eurofins and SGS laboratories.

Each partner contributes its expertise toward project success:

  • Lyonnaise des Eaux – operating complex wastewater treatment plants.
  • Degrémont Services – construction and engineering expertise to ensure successful project completion.
  • Réseau GDS – feeding-in produced biomethane and its commercial use as household gas.
  • SGS and Eurofins – laboratory analysis and expanding knowledge of the biogas cycle.

Biovalsan will reduce the Strasbourg-Wantzenau wastewater treatment plant’s environmental footprint by 66%, thereby:

  • More than doubling the city of Strasbourg’s 2020 target (30% reduction in CO2 emissions), 5 years ahead of schedule.
  • Achieving 90% of the European Energy Package’s 2050 objective (Factor 4), 35 years ahead of schedule.

Thus the Biovalsan project will make a major contribution to the Territorial Climate Plan objectives of the City and Urban Community of Strasbourg.
