France-headed Waga Energy SA, a global expert in the production of biomethane (aka renewable natural gas – RNG) from landfill gas (LFG), has announced that it has signed a contract with FCC Medioambiente to upgrade the landfill gas of the Ecocentral site in Alhendín, in the province of Granada, Andalusia, Spain.
FCC Medioambiente operates the Ecocentral site on behalf of the Diputación de Granada. Scheduled to start up in 2028, the unit will produce around 273,000 MMBtu (80 GWh) of RNG per year, equivalent to the annual gas consumption of approximately 16,000 average households in Spain.
Under the ten-year contract, Waga Energy will finance, build, own, and operate a WAGABOX upgrading unit based on its patented technology, designed to treat up to 1,500 scfm (2,400 m3/h) of LFG.
The RNG will be injected directly into the local gas grid via a connection of approximately 6 km built as part of the project. Waga Energy will sell the RNG and share the revenue with FCC Medioambiente.
By converting methane generated by waste into RNG, a substitute for fossil-based natural gas, the project will avoid approximately 19,000 tonnes of carbon dioxide equivalent (CO2eq) emissions per annum.
The Ecocentral WAGABOX facility is a tangible example of the circular economy at work, transforming gas generated by waste into a local source of renewable energy. By creating economic value from this captured gas, the project will help turn a local environmental challenge into a resource for the region, said Baptiste Usquin, CEO of Waga Energy Spain.
The Ecocentral contract, signed in November 2025, marked Waga Energy’s third of four projects in Spain to date. Globally, Waga Energy has 59 projects in its project portfolio.
Waga Energy operates 38 RNG production units in France, Spain, Canada, and the United States, representing an installed production capacity of 2.1 TWh per year. Twenty-one units are under construction in France, Italy, Spain, Brazil, Canada, and the United States.
