Resource efficiency and industrial ecology in the Versailles Plain and the Alluets Plateau, France: Feasibility study of four pilot projects


Wealth Association of the Versailles Plain and the Alluets Plateau

Project dates


Context and objectives

  • Creation of the APPVPA in 2004 to bring together individuals and corporations representing local interests. This provided a space for reflection, assessment and proposal for the development of a sustainable development project in the area.
  • Grouping of 24 towns representing 130,000 people, 17,000 hectares of which 8,000 are cultivated.
  • Willingness for the Versailles Plain to be a pilot area in industrial and territorial ecology, financially supported by the FEADER fund, ADEME and the Ile-de-France Region.
  • Conduct a feasibility study on four pilot projects of industrial and territorial ecology related to:
  1. The valorization of hot water treatment plant output
  2. The valorization of sludge for energy or material recovery
  3. The development of a local biomass energy sector
  4. The heat network development


  • Study and detailed description of the examined systems.
  • Confirmation of the potential re-use of hot water output from WWTP and pre-scaling.
  • Comparative analysis of the opportunities of valorization of WWTP sludge through field visits and interviews with local stakeholders.
  • Statistical report of available biomass resources of the area.
  • Analysis of the heat demand of the Plain and the potential for heating network.
  • Analysis of the stakeholder’s role in the local biomass energy sector.
  • Guidelines for the development of local biomass energy sector.
  • Preliminary studies for concrete possibilities of networks development
