The facility, designed, built and operated by Veolia, allows for the valorization of industrial streams with a high organic load through anaerobic digestion and their subsequent conversion into biomethane via an advanced purification system.
It treats 105 m³ of liquid industrial waste daily and achieves a production of more than 8,000 m³ of biomethane per day, equivalent to more than 32 GWh of renewable energy per year.
This is the first time in Spain that this technological configuration has been applied to liquid industrial waste, which is characterized by a greater complexity of treatment than conventional agricultural and livestock flows, representing an advance in the energy valorization of industrial streams.
To ensure the efficiency of the process, the plant integrates three technologies proprietary to the Veolia Group: the digester Memthane®, anaerobic digestion reactor with membrane technology and a capacity of 4,000 m³; the system Sulfothane™ biological desulfurization of biogas; and the technology MemGas™, responsible for the final purification to meet the strict standards required for injection into the natural gas network.
Biomethane production prevents the emission of more than 8,000 tons of CO₂ per year and confirms the potential of energy recovery from industrial waste as a real decarbonization tool for Spanish industry. The injection system became operational in December 2025.
