Ferrovial Servicios, a leading global service operator, has selected Waga Energy to produce biomethane at the Can Mata landfill, one of Spain's largest landfill, near Barcelona. The site will be the first in Spain to use the WAGABOX purification technology, developed by Waga Energy to recover landfill gas in the form of biomethane, a renewable substitute for natural gas.
The WAGABOX unit at the Can Mata site will be commissioned in 2022. It will treat up to 2,200 m3/h of landfill gas and inject 70 GWh of biomethane per year into the gas grid of the Spanish operator Nedgia, which is equivalent to the annual energy consumption of 14,000 Spanish households or 200 lorries. The project will avoid the emission of 17,000 tonnes of CO2 per year by substituting renewable gas for natural gas.
The project will be the first-ever landfill gas injection project to be financed by a long-term power purchase agreement in Europe. This method of financing is common for renewable electricity projects but rarely used for green gas projects, generally unable to provide buyers with a competitive price over the long term.
