The project consists of the realization of an anaerobic digestion unit on existing agricultural fields. It is located in the municipality of Blajan (31), at the crossroads of the departmental D55 and the rural road called Vignes, for a total area of 45,250 m2. The surrounding properties are mainly agricultural estates. The project was initiated by the operators of SAS METHABOUL' grouped together to set up a common tool allowing them to manage livestock manure and improve their autonomy in terms of fertilization thanks to the digestate produced by methanization. The methanization project envisaged by SAS METHABOUL' is an extension of the agricultural activity of farmers and farms that provide almost all inputs (manure, slurry, Intermediate Energy Vocation Culture (CIVE summer, CIVE winter) with the desire to valorize manure and slurry but also by manufacturing fertilizers through the use of digestates produced by methanization. The digestate, a natural fertilizer resulting from the digestion of the materials integrated into the unit, will be applied on the agricultural plots of the operators who provide substrates to the project around the methanization unit as a replacement for mineral fertilizers. The project will increase the autonomy in fertilizer and therefore in feeding the herds of each. The transport of inputs will be carried out by the contributing farmers and by transporters.
