Realization of an observation program of anaerobic digestion and deconditioning units in Grand Est (surveys on 2023, 2024, 2025 data and their exploitation)

Collection, on the Grand Est perimeter, through annual surveys carried out in 2024, 2025 and 2026, of data for the years 2023, 2024 and 2025 from anaerobic digestion plants of the type:- "on the farm" or agricultural methanization, units treating mainly effluents and agricultural substrates;- "centralized" (or "territorial"), large units treating agricultural effluents in minority and more waste from the territory;- industrial (e.g. in the sectors of the agri-food, chemical and paper industries); - in wastewater treatment plants (WWTPs), units treating sludge for the treatment of urban wastewater. In addition, each annual survey will include an inventory of biowaste deconditioning equipment, whether or not linked to a biogas plant. For each survey, the data collected will be used annually, with the production of indicators and analyses, as well as the production of communicating summary sheets of the survey results.
