2 wastewater and methanisation What exactly is it about? Wastewater Treatment Treated water BIOGAS Production of a local and low carbon green energy + digester Biogas production (65% méthane) Beneficial use CO-Méthanisation Stabilisation and reduction of sludge volume Local valorisation of territorial organic waste + boost biogas production + valorise infrastructure Sludge treatment line LESS SLUDGE 30% minimum od sludge disposal = 30% less problems Beneficial use 2 I OFATE 21 septembre Paris

3 wastewater and methanisation an overview of the situation in France 100% of WWTP > EH In France, 85% of WWTP (> PE) without digesters For a city of residents, methanisation leads to ~ 3 Gwh/year of biomethane and the capacity to supply in biofuel Sludge digestion Germany / France 2014 Biomethane potential in France 420 units > EH 20 OU 20 OU Bus Refuse collection vehicule 600 units 60 units only 15% of WWTP = GWh/year Equivalent to the production of 350 wind turbines 100 Cars Or in natural gas 900 LEB houses 3 I OFATE 21 septembre Paris

Feedstock Pretreatment & Conditioning Characterisation Methanisation Beneficial use of biogas Beneficial use of digestat Depackaging of Biowaste + 10 co-methanisation Grease from food industries, unsold food from supermarkets, distillery waste, whey, waste from food industries, manure, Sauerkraut juice. Dedicated department METHALab- METHAmax Significant R&D investments (10 Million euros over 10 years) More than 1100 analysis of co-substrates Pilot-lab and Pilot-scale demonstration Development of a predictive tool to optimise design and operating of digesters. 7 I OFATE 21 septembre Paris
