Plant of San Millán de los Caballeros
San Millán de los Caballeros, León, Spain
Solarig, through Biorig, is developing a 90 GWh/year biomethane production plant located near the municipality of San Millán de los Caballeros, León. The project has a planned investment of 26 million euros, will promote more than 35 jobs and is expected to be operational by the end of 2025.
The facility will recover local agricultural and livestock waste, producing a renewable gas that will prevent the emission of more than 30,000 tonnes ofCO2 per year. The plant will incorporate state-of-the-art technology to capture 10,000 tonnes of biogenicCO2 per year, and will generate by-products that will contribute to the sustainable fertilisation of the region’s agricultural land.
This new plant will allow the revalorisation of more than 150,000 tonnes of agricultural and livestock waste per year. It will also produce by-products of high agronomic value for local farmers, thus helping to comply with sustainable fertilisation plans for agricultural soils.
San Millán will have 9 digesters, each with a diameter of 35 metres, a height of 8 metres and an effective capacity of 6,400 m³. The new plant will enable the recovery of more than 198,000 tonnes of agricultural and livestock waste per year (slurry, straw and manure) and will return 211,000 tonnes of CFP3 organic fertiliser per year to local farmers, certified in accordance with EU Regulation 2019/1009. This will help farmers comply with sustainable fertilisation plans for agricultural soils.
The plant's waste treatment areas will be waterproofed to prevent spills or seepage. It will also feature water reuse systems to avoid the consumption of external water, as well as odour detection and prevention systems. The project is expected to become operational in 2027.
