Jean Rottner, President of SIVOM, and Marie-Ange Debon, Senior Executive VP of SUEZ in charge of France, Italy and Central Europe, laid the first stone of a methanation unit that will allow 100% recovery of sludge from the Sausheim, France wastewater treatment plant to supply green energy for the equivalent of 125 urban transport buses by 2020.
Sludge collected from the methanation process can be centrifuged and its solid residue recovered as energy.
At the end of the 21-month project, in mid-2020, the facility will produce 2 million m³/yr of purified biomethane, which will be injected into the GRDF network, supplying 19 GWh/yr of energy.
