Potential waste deposits available for anaerobic digestion in France

The ADEME (The environment and energy control agency of France) has recently published an estimate number of potential waste deposits available for anaerobic digestion by 2030, for France. The different wastes taken into account are:

  • The agricultural wastes: livestock manure, crop residues, intermediate crops to energy-supply purposes;
  •  the resources of food and drink industries (F&D Industry) by sectors of activity;
  • the resources of sanitation;
  • green waste;
  • organic waste from households;
  • organic wastes from restaurants, small businesses, retailers and markets.

The following waste resources have been identified as usable for anaerobic digestion but because of difficulties to evaluate other kinds of resources, ADEME did not object to a quantitative assessment to 2030 of:

  • Green algae,
  • Microalgae,
  • The production of fruit and vegetables.

The global waste deposit by 2030 usable for anaerobic digestion was thus assessed to 130 million tons, for a potential production of biogas around 56 TWh. This global waste estimation is composed of 90% of agricultural wastes.

This global waste usable represents around 30% of the global waste deposit in France.

However, regarding ADEME’s study, by integrating resources such as roadside mowing grass, native grasslands and summer CIVE (Culture intermediate to Energy Vocation, that grows between a main crop harvest and seeding of the next) and, under certain conditions of changing agricultural practices and land uses; the available net deposit could reach 240 TWh and the usable deposit could exceed the 70 TWh by 2030.

These figures, even if they don’t give any more incentive, confirmed that Biomass could become a major source of energy production by 2030 in France. The release of this study remains auspicious for the government who recently declared that they want to further assess the simplification of procedures for bio-energies, stressing for example, that single permit experimentation for anaerobic digestion is ongoing.
