Spain’s Aqualia successfully produces biogas from wastewater treatment

September 21, 2021 |

In Spain, transforming waste from the agri-food industry into high value-added products such as energy, biofuels, biofertilizers and biodegradable plastics is already a reality in the biorefinery developed by Aqualia in the Guijuelo treatment plant (Salamanca)/

The agri-food industry is an important economic engine in Salamanca, and the management of its waste poses a significant challenge as it carries a significant cost. Faced with this concern, the Guijuelo City Council, Aqualia and the Guijuelo Slaughterhouse (MAGUISA) joined forces in 2019 with TeCH4 + and Bionet Engineering to develop the solution proposed in the ADVISOR innovation project in the local treatment plant, with the aim of maximizing the use of bio-waste in existing infrastructures.

With the treatment of one ton of the bio-waste studied in Guijuelo, biogas is obtained to circulate up to 2,000 kilometers. This means that the use of 100% of the renewable biogas obtained from the 3,000 tons of bio-waste currently treated in the biorefinery would allow driving the distance to and from the moon 80 times a year, more than one lunar trip to the week.

Two vehicles already circulate with the biomethane obtained in the treatment plant facilities. The biogas plant can supply up to 50 vehicles, taking advantage of part of the biogas obtained thanks to the transformation of the 3,000 tons of bio-waste that for now are treated in the Guijuelo biofactory.
