Last month, the biomethane produced during the purification process of wastewater from the Bens Wastewater Treatment Plant (WWTP) in A Coruña began to fuel the first public bus that runs on renewable natural gas throughout Spain. The vehicle belongs to the transport company Cal Pita.
The bus will cover the route that connects the stops of A Coruña, Perillo, San Pedro, O Carballo, Osedo and Sada. It will make an average of 80,000 kilometers per year, which means a significant reduction of polluting tons per year.
The bus technology has been developed thanks to the collaboration of Bens WWTP, Naturgy and the EnergyLab Technology Center, and it is an example of the viability of the circular economy model. This pioneering project ensures the supply of constant raw material, economic savings and also the reduction of CO2 emitted into the atmosphere.
“This project arose because we had 100 cubic meters left over at the Bens WWTP. We generate 450 cubic meters of gas per hour, a part we use for the facilities and another part for the biodigesters,” said the general director of Bens WWTP Carlos Lamora. The goal for this year is to inject this biogas into the distribution network so that it reaches homes.
Biomethane is a clean and renewable energy and will be one of the many topics to be addressed at AltFuels Iberia 2019, taking place on 11-14 June at IFEMA Trade Fair Center, in Madrid.
It will be an event consisting of first level conferences and exhibition of vehicles of all kinds, refueling stations, components, plants, road and marine engines, as well as the entire universe of the alternative fuels industry with the latest technological developments, multiple options for networking, business and new advances.
