Biomethane from the Bens Wastewater Treatment Plant, in the Spanish province of La Coruña, will be the fuel for local public vehicles once the mixed renewable gas unit starts operating in September after a period of proof.
The Councilor for the Environment, María García, recently announced that in a few weeks “A Coruña can become a benchmark in terms of energy efficiency systems, when the mixed unit of renewable gas provided in the Bens WWTP begins to operate”.
The biomethane will be used as fuel and will facilitate the circulation of a public bus, as well as the vans of the purification plant and a van used by Mujeres Colleiteiras, which develops a circular economy project in collaboration with the City Council of A Coruña for the use of household oils.
Specifically, this pilot project, which will be carried out until 2019, will make possible to take advantage of the biogas produced naturally in the processes of anaerobic digestion of organic matter in the Bens wastewater treatment plant.
This innovative procedure was launched by the public company of the Bens WWTP (of which the municipalities of La Coruña, Arteixo, Cambre, Culleredo and Oleiros are part), with Naturgy SDG, Naturgy Engineering and the EnergyLab technology center, and has an investment of 2.2 million euros from the Galician Innovation Agency.
