英文摘要	If Waste Water Treatment Plants are especially well performing about the quality of treated water, it has to be noted that the water industry use approximately 3.5% of UE electricity consumption for pumping, water treatment and waste management. The challenge is to move towards energy self-sufficiency, cut carbon and exploit all the opportunities for customer-controlled energy. Anaerobic Digestion and Gaz Network Injection technology is advancing rapidly, with gas cleaning systems already generating U4GWhHHV/year (Feedback Gaz reseau distribution France GRDF), with a total potential assessed at more than 1,500GWhHHV/y. Renewable energy from biogas will help drive the industry towards genuine carbon neutrality and energy self-sufficiency. This article presents the case study of the new injection plant at Angers Loire Metropole. It has been injecting the biomethane issued from the AD into the natural gas network since June 2017. Around 15,000 MWh HHV per year are aldreay injected and this capacity will be soon increased by optimising the process to heat the digestor. This production has to be compared to the consumption annual electricity: around 9,000 MWh/year. Depending on the conversion coefficient used, 2.58 in France under the RT 2012, the self sufficiency will soon be 77.6%. One step further is needed to be really self sufficient! As treatment processes may be further optimised thanks R&D, the opportunity for greater energy self sufficiency and renewable energy export will rise. This would be further increased if any spare capacity could be used for the co-digestion of energy crops or other liquid organic wastes depending on regulation rules under discussion. © 2020 Techniques - Sciences - Methodes.
