Investing for the planet: Smart Met Value Project

Facing new challenges is one of our favorite things, especially when it comes to providing an innovative solution to it. The Smart Met Value Project one of these challenges, our objective for this project was to recover the energy of the biogas generated in the anaerobic digestion process of wastewater, by transforming it into biomethane, a renewable biofuel with the same properties as conventional natural gas. You could say, we were trying to make fuel out of thin air.
The solution we provided was developed at our Wastewater treatment plant (WWTP) located in Guadalajara (Spain). Sacyr Agua along with Alfonso X El Sabio University and the Gómez Pardo Foundation, a part of the Higher Technical School of Mines and Energy Engineers of the Polytechnic University of Madrid, were successful in developing a new biogas cleaning system that obtained a quality biomethane suitable for grid injection among other uses, such as automotive. The key to this new technology lies in its first phase, with the absorption of the biogas and a high-efficiency methane purification technology, that have significantly lower energy consumption than the ones currently used.
This project backed by a budget of 834.867 €, financed by the Center for Technological and Industrial Development (CDTI) and co-financed by the European Regional Development Fund (ERDF) through the Multiregional Intelligent growth Operational Program 2014-2020, has a lot of partners working together to keep the planet save. 
At Sacyr we are always looking at ways to contribute to the circular economy while helping to keep our planet safe. In this case we’ve done so by reducing greenhouse gas emissions, improving the efficiency in the integral water cycle system and by obtaining domestic and renewable fuel.
