  • The main objective of the biogas plant is the valuation of feedstock: agro-industrial residues, energy crops and livestock products.
  • Biogas will be the main product produced, which will then be used to produce electricity.
  • Energy production is based on biomethane technology. Biomethanisation is conducted in eight controlled anaerobic digesters designed so that the total retention time is sufficient for complete degradation of organic matter.
  • The biogas plant will generate electricity in parallel with the interconnection distribution network. The installation will generate at a manageable rate given that it will warehouse raw material and may be independently operated for more than one week.
  • The thermal energy generated in the process will be utilized in part to heat the digesters, and in part to dry grain silage.
  • In addition to the generation of gas, electricity and heat, the plant will generate some important by-products. The main product is the effluent of the anaerobic digestion, called digestate. It is a liquid product, homogeneous and with high value as organic fertilizer. The crude digestate is separated in a solids separator, obtaining a liquid fraction and a solid fraction. Both have agricultural application due to their high value as organic fertilizers. In months when the application to the soil is not possible, the liquid fraction is stored in airtight storage barrels and buried, while the solid fraction is removed and transported to waste sites by containers.

The main objective of the Villena biogas plant is the valuation of feedstock: agro-industrial waste, energy crops and livestock products for the production of clean, renewable energy in the form of biogas.
