About the proyect
The San Millán de los Caballeros plant (León), a pioneering facility in the development of biomethane in Spain, will have a production capacity of 119 GWh, equivalent to the consumption of almost 21,000 homes. This facility has an investment of around 35 million euros, it will contribute to the economic development of the municipality with the creation of 100 jobs during its construction phase and 35 direct and indirect jobs during its operation.
San Millán de los Caballeros will have 9 digesters, each with a diameter of 35 metres, a height of 8 metres and an effective unit volume of 6,400 m³. This facility will recover a maximum of 198,000 tonnes of agricultural and livestock waste per year (slurry, straw and manure) and will return 211,000 tonnes per year of organic fertiliser CFP3 approved by EU directive 2019/1009 to the agricultural community of the region.
The plant will be waterproofed in the waste treatment areas to prevent spillage or leaks, has water reuse systems to avoid external water consumption and has odour detection and prevention systems. The project is expected to be operational in 2027.
