In France, landfill gas to biomethane technology provider Waga Energy SA has announced the commissioning of a landfill gas to biomethane unit at the Granges landfill in Burgundy, eastern France. This marks the sixth renewable natural gas injection project undertaken with global resource management company Veolia these past six years.
The Granges landfill in Burgundy is operated by Veolia’s subsidiary, Valest.
Using the WAGABOX technology, developed by Waga Energy, the landfill gas (LFG) emitted by the decomposition of landfilled waste is upgraded into renewable natural gas (RNG), a renewable substitute for fossil-based natural gas.
The RNG is directly injected into the gas distribution network to supply households and businesses.
Capable of purifying 375 Scfm (600 Nm3/h) of LFG and producing up to 85,300 MMBtu (25 GWh) of RNG per year, the unit can supply more than 3,000 homes while avoiding around 3,300 tonnes of carbon dioxide equivalents (CO2eq).
Replaces a genset unit
The Granges landfill processes up to 130,000 tonnes of waste per year. Previously, the LFG was used to fuel two cogeneration engines for combined heat and power (CHP) production.
The WAGABOX unit replaces one of these gensets upgrading the LFG to RNG enabling higher energy efficiency while the RNG can replace fossil fuels (oil and natural gas) for transportation, manufacturing, and heating needs, which account for a significant proportion of greenhouse gas (GHG) emissions.
RNG production also helps to improve the community’s energy independence.
Sixth RNG injection project
The completed project marks the sixth RNG injection project undertaken in France by Veolia and Waga Energy in the last six years.
The WAGABOX units located at Veolia landfills offer a combined installed capacity of 800,000 MMBtu (235 GWh) per year, supplying over 35,000 households with RNG and avoiding the emission of more than 40,000 tonnes of CO2eq annually.
This sixth RNG project carried out with Veolia reflects the successful cooperation between a large multinational company and a young and innovative company, joining forces to make a concrete contribution to reducing greenhouse gas emissions. I am pleased and proud of our constructive collaboration, and particularly the impact of our jointly developed projects in an effort to protect the planet, said Mathieu Lefebvre, CEO of Waga Energy.
