Development of biomethane facilities in Castilla y León

Biorig will develop 10 biomethane production facilities in Castilla y León. These infrastructures are of a strategic nature for the sustainable rural development of the community and are essential for the proper management and long-term recovery of waste in the territory.

Plants operational by the end of 2025

The company will develop a total of 10 facilities for the production of clean energy, equivalent to the consumption of 20% of the annual gas consumption of homes in Castilla y León. The plants are expected to be operational by the end of 2025.

Six locations in Castilla y León

The plants will be located in rural areas of municipalities in Castilla y León, in the provinces of León, Zamora, Salamanca, Valladolid, Burgos and Soria. The facilities will always be located in rural environments and far from any urban centre.

Valorisation of agro-livestock waste

More than 1.5 million tonnes of agricultural and livestock waste will be recovered, producing a renewable gas that will prevent the annual emission of 300,000 tonnes of CO₂ into the atmosphere. The by-products or digestate will be treated to become organic fertilisers, which will contribute to reducing dependence on chemical fertilisers and to a more sustainable fertilisation of agricultural soils. Waste will be sourced from localities within a maximum radius of 25 kilometres of the facilities.

Economic development and job creation

The development of the ten facilities will boost wealth and population fixation by creating more than 350 local jobs, direct and indirect, in the different phases of design, construction and operation. They will provide local economic benefit and growth in key sectors in Castilla y León such as agriculture and livestock.

Reuse of water for zero consumption

Biorig’s facilities are designed to have zero water consumption by taking advantage of rainwater to be used in the production circuits. In addition, once the organic waste is decomposed, such as slurry, it goes through a solid-liquid separation system that allows the resulting liquid fraction, which is 97% water, to be recirculated and used in the production processes. The system is designed to ensure zero water discharge.

Biogenic CO₂ capture

The facility will be equipped with state-of-the-art technology to ensure zero emissions: biogenic CO₂, an essential element for the production of green methanol and SAF (sustainable aviation fuels), will be captured at the facility. Once the waste is received at the plants, it is stored in a fully sealed silo for further processing. In this sense, the plants designed by Biorig do not emit odours or any type of pollution.
