Conceptual design and financing plan for an anaerobic digestion plant for organic waste from the agri-food and livestock industry in Gipuzkoa
Spain
In Gipuzkoa, the agri-food and livestock industry generates a significant amount of organic waste, reaching figures that require sustainable and efficient solutions for its management. The use of this waste as a raw material for biogas production combines the benefits of renewable energy production with sustainable waste management. It also has a threefold purpose: to contribute to the reduction of greenhouse gas emissions and other atmospheric pollutants, to improve waste management and to make use of the energy it contains.
IDOM worked on the development of a conceptual and financing scheme
Through a collaboration agreement financed by the Provincial Council of Gipuzkoa, CEIT carried out a study from August to December 2024 on the feasibility of a biomethanisation plant for the management and treatment of industrial organic waste produced in Gipuzkoa. As part of this project, IDOM was contracted to develop a conceptual design and financing scheme for an anaerobic digestion plant for the agri-food and livestock industry, with a treatment capacity of 75,000 tonnes/year of waste, without a specific location.
The project was based on IDOM’s extensive experience in similar projects, covering both technical and economic aspects. The activities carried out included:
- Analysis of the regulatory aspects applicable to anaerobic digestion plants for the generation of biogas/biomethane, CO2 capture and recovery, and the production of fertiliser from digestate.
- Selection of the main design criteria and characteristics.
- Analysis of possible emissions, effluents and waste generated.
- Process flow diagram.
- Mass and energy balances for the plant.
- Definition of a preliminary plan for the plot and the required footprint.
- General design, elevations and maximum height of the infrastructure.
