Currently, German biogas specialist WELTEC BIOPOWER is building a biomethane plant for the Spanish dairy cattle farm Torre Santamaría. Since the first 250-kW biogas plant went live back in 2011, the Catalan family business has been able to cover its entire energy demand from its own residues. The farm in Vallfogona de Balaguer was the first milk producer in Spain to use any residual materials for the production of energy.
