The Lugère biomethane plant was recently inaugurated; a project that brings countless benefits to the city of Orléans. Here, in fact, 258 Nm3/h of biomethane is produced, fed into the GRDF gas network. Biomethane derives from the anaerobic digestion of over 70 tons of substrates per day, 40% of agricultural origin (manure and plant residues) and 60% of agro-industrial origin. The biomethane produced is equivalent to the consumption of about 2000 homes in Orléans. Last but not least, the use of 25,000 tons of digestate resulting from anaerobic digestion, allows to avoid over 5000 tons of CO2 per year, partially replacing the use of chemical fertilisers.
