In southwestern France, regional municipal waste management authority Syndicat Mixte Départemental des Déchets de la Dordogne (SMD3), and compatriot landfill gas (LFG) to renewable natural gas (RNG) technology provider Waga Energy SA have signed a contract to produce RNG at the Saint-Laurent-des-Hommes landfill in Dordogne department.
Located in the city of Saint-Laurent-des-Hommes in southwestern France, the landfill can process up to 75,000 tonnes of waste a year, and landfill gas (LFG) is currently used for electricity generation.
Waga Energy will build a purification unit at the landfill in Saint-Laurent-des-Hommes, using its patented WAGABOX technology to upgrade LFG into RNG–aka biomethane–a renewable substitute for fossil natural gas.
Better energy efficiency
The RNG will be directly injected into the natural gas distribution network to supply households and businesses.
Upgrading it to RNG will achieve higher energy efficiency, supplying renewable energy directly into the gas pipeline.
RNG represents a solution for decarbonizing specifically hard-to-electrify sectors such as industry and transport while helping to boost local energy sovereignty.
Jointly developed with Waga Energy, this innovative project marks a new step forward in Dordogne’s energy transition. By upgrading the energy produced from the waste of Périgord’s residents to renewable natural gas, we are delivering clean and local energy while reducing our fossil fuel dependency and protecting the planet, said Pascal Protano, President at SMD3.
Circular economy
The WAGABOX unit will produce around 57,000 MMBtu of RNG (16.7 GWh) annually, supplying 3,000 local households.
Scheduled for 2027, its commissioning will avoid the emission of 4,000 tonnes of carbon dioxide equivalent (CO2eq) annually, by replacing fossil natural gas with RNG.
This initiative with SMD3 reflects our shared commitment to supporting the energy transition. We are thrilled to be able to provide the people of Dordogne with a pioneering solution that converts methane into RNG – a local and renewable energy offering a genuine alternative to fossil-based gas, said Mathieu Lefebvre, CEO of Waga Energy.
