Biogas is a renewable gas that is fundamental for advancing towards a sustainable economy and has great potential for decarbonization. It can be used to produce electricity and heat, especially in industrial environments where electrification is not possible.
Biogas is obtained from organic waste, specifically, from municipal waste, agri-food industries, sewage sludge, crop residues, and livestock manure. Therefore, it contributes to promoting the development of the circular economy and allows for the management of these wastes.
The most advanced way to produce biogas is through anaerobic digestion, a process through which organic matter is decomposed by microorganisms.
Its development allows territories and industries to produce local, storable, and clean energy, which has a positive impact on the economy and employment in rural areas, facilitating a just energy transition.
For its part, biomethane, is a source of renewable, local and storable energy, with already-available technology that allows reducing emissions in the short term and contributes to the development of the circular economy, as it is the result of greater waste valorization. Its use also reduces emissions into the atmosphere.
It is produced by subjecting biogas to a technological process called enrichment or upgrading. It is considered an essential energy carrier to meet European decarbonization targets and to promote the development of the circular economy.
It can be transported via existing gas infrastructure and has multiple energy uses in all sectors, including those that are difficult to electrify such as the thermally intensive industry. It can also be used by households and as a sustainable fuel for vehicles.
Learn more about our projects
- This plant is located in Burgos, next to the existing biogas production facility of Biogasnalia.
- It is the first large-scale project in the field of biomethane connected to the Spanish gas network carried out in the country by a private initiative.
- The plant has been in operation since 2021, injecting the produced biomethane into the distribution network owned by Nedgia.
The project consists of a biowaste treatment plant located in Colmenar Viejo which will allow the recycling of separately collected organic waste. The project includes:
- An anaerobic digestion plant for the production of biogas and a biogas upgrading plant to produce biomethane
- A digestate treatment plant to produce compost
The produced biomethane will be injected into the gas grid, contributing to the incorporation of renewable energy sources in the energy mix.
This project has been funded by the European Union-NextGenerationEU under the Spanish Recovery, Transformation and Resilience Plan through the Community of Madrid.
- Investment budget of the project: €21.5 million
- Financed budget: €7.9 million
- Amount of granted aid: €3.3 million
