Waga Energy has signed a ten-year agreement with FCC Medioambiente to convert landfill gas from the Ecocentral site in Alhendín, near Granada, into renewable natural gas. Due to begin operating in 2028, the facility is expected to produce around 273,000 MMBtu, or 80 GWh, of RNG annually, equivalent to the yearly gas consumption of approximately 16,000 Spanish households. The project is designed to treat up to 1,500 scfm, or 2,400 m³/h, of landfill gas and avoid an estimated 19,000 metric tonnes of CO₂ equivalent emissions each year. It provides a practical example of how landfill methane can be recovered and used as a local energy resource rather than released into the atmosphere.
A New RNG Facility
The Ecocentral project will see Waga Energy finance, build, own and operate a WAGABOX® upgrading unit at the landfill in Alhendín, in the province of Granada. FCC Medioambiente operates the site on behalf of the Diputación de Granada, while the two companies will share revenue from the sale of the resulting renewable gas.
The installation will use Waga Energy’s patented WAGABOX® technology to purify landfill gas and produce RNG, also known as biomethane. A roughly six-kilometre connection will be developed as part of the scheme, allowing the gas to be injected directly into the local gas grid.
That direct grid connection gives the project a clear route from captured landfill gas to homes and businesses supplied through the existing distribution network. In place of fossil-based natural gas, the recovered fuel is intended to provide a renewable substitute derived from waste already present at the site.
Turning Methane Into Energy
Landfills generate methane as organic materials decompose. Capturing that gas and upgrading it for network injection creates an alternative use for a potent greenhouse gas while producing renewable energy close to where the waste originated.
At Ecocentral, the planned annual production of 80 GWh is expected to match the gas use of around 16,000 households in Spain. The project’s anticipated annual avoidance of 19,000 metric tonnes of CO₂ equivalent highlights the climate value associated with methane capture and fossil gas substitution.
The project also places waste management and energy production within the same local infrastructure. Rather than treating landfill gas solely as an operational by-product, the scheme is structured around its recovery, purification and commercial use.
Baptiste Usquin, CEO of Waga Energy Spain, said:
“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.”
Shared Project Structure
Under the agreement, Waga Energy will take responsibility for financing, construction, ownership and operation of the upgrading facility. The arrangement provides FCC Medioambiente with a route to monetise recovered landfill gas through a revenue-sharing model, while maintaining its role as operator of the Ecocentral site for the Diputación de Granada.
The contract was signed in November 2025 and became Waga Energy’s third project signed in Spain. The company has now signed four projects in the country, with Ecocentral included within its wider portfolio of 59 projects.
For Granada province, the development combines landfill-gas management with an additional domestic source of renewable gas. The six-kilometre network connection is an important element of that proposition, enabling production at the landfill to enter the local gas system rather than requiring a separate end-use arrangement.
Expanding International Capacity
Founded in 2015, Waga Energy develops renewable natural gas projects by upgrading landfill gas through its WAGABOX® purification technology. The company’s approach centres on injecting the resulting RNG into gas distribution networks that supply households and businesses.
As of the release date, Waga Energy operates 38 RNG production units across France, Spain, Canada and the United States. Those facilities represent installed capacity of more than 7.1 million MMBtu, or 2.1 TWh, per year.
The company also has 21 units under construction in France, Italy, Spain, Brazil, Canada and the United States. The Ecocentral facility adds to this expanding project base while demonstrating the relevance of landfill-derived RNG to Spain’s local energy and emissions objectives.
A Circular Regional Resource
Scheduled for 2028 start-up, the Ecocentral project brings together landfill operation, methane recovery, gas-grid infrastructure and renewable fuel production in a single regional development. Its production scale, household-equivalent output and projected emissions savings give the project a tangible role in converting a waste-derived gas stream into usable energy.
For Waga Energy and FCC Medioambiente, the agreement offers a commercially structured route to recover value from landfill gas while reducing reliance on fossil-based natural gas. As Spain adds renewable gas capacity, projects such as Ecocentral show how existing waste sites can contribute to local energy supply and emissions reduction.
