At Sigma, the commitment to the planet goes beyond food production. The Company believes in a future where the food industry is more sustainable. Its Campofrío Frescos plant, in Burgos, Spain, created a strategic alliance with Biogasnalia for the generation of biogas, which is a renewable fuel used at this site since the end of 2023. The alliance’s main objective is to revalue organic by-products through anaerobic treatment.

This process resulted in the production of 12,000 MWh of energy per year, which represents the migration of 40% of natural gas consumption to biogas and a reduction of 2,100 tons of CO2 emissions annually. Campofrío Frescos uses biogas to generate thermal energy for various activities within the plant such as water heating and cleaning processes.
