Séché Environnement and Waga Energy start up a RNG produc:on unit in North of France

Séché Environnement, an interna@onal player in the circular economy and environmental services, and Waga Energy (EPA: WAGA), a global expert in the produc@on of Renewable Natural Gas from landfills, have started up a Renewable Natural Gas (RNG) produc@on unit at the Opal Environnement site, a subsidiary of the Séché Environnement group, in Sainte-Marie-Kerque (Northwestern France). Using the innova@ve WAGABOX® technology, developed and patented by Waga Energy, the plant recovers the gas spontaneously emiWed by landfilled waste in the form of RNG, a renewable subs@tute for fossil-based natural gas. Its renewable gas produc@on is injected directly into the local gas grid to supply homes and businesses.

The WAGABOX® unit at Sainte-Marie-Kerque can process 500 scfm (800 m3 /h), and produce up to 120,000 MMBtu (35 GWh) of RNG per year, depending on the concentra@on of methane in the raw gas. At its maximum capacity, it can supply around 5,500 households and avoid the emission of 5,800 tons of CO2 equivalent per year into the atmosphere, through the subs@tu@on of fossil-based natural gas in the grid1 .

The gas emiWed at the Sainte-Marie-Kerque landfill was previously upgraded by a power engine. The WAGABOX® unit will significantly increase the landfill energy produc@on, providing energy that will help to decarbonize sectors such as transport and industry – s@ll totally dependent on fossil fuels.

Maxime Séché, Chief Execu1ve Officer of Séché Environnement, said: "This RNG produc@on plant illustrates the Séché Environnement group's commitment to circular economy and ecological transi@on of territories and industries. It is part of the group's decarboniza@on strategy presented in February 2022, and its ambi@on to curb its greenhouse gas emissions by 25% by 2030."

Mathieu Lefebvre, Chief Execu1ve Officer of Waga Energy, said: "Thanks to the WAGABOX® technology, the Sainte-Marie-Kerque landfill has become a RNG producer, and now supplies the local community with low-carbon energy. We are delighted about – and proud of – this first collabora@on with the Séché Environnement group, a long-standing and recognized player in waste management, strongly commiWed to figh@ng global warming and reducing greenhouse gas emissions."
