InproEner is a Spain-based renewable gas company focused on the development and engineering of biogas and biomethane projects. The company works across the project lifecycle—from feasibility and permitting to plant design, construction, and operation—centered on anaerobic digestion of agricultural, livestock, and agro‑industrial residues and the upgrading of biogas to grid-quality biomethane.
Its activities typically include feedstock assessment and logistics, process engineering, gas upgrading technologies (such as membrane or PSA systems), grid injection or on-site use, and by‑product management (e.g., digestate valorization). InproEner’s projects support decarbonization of industrial energy use and transport, while advancing circular economy practices through the recovery of energy from organic waste.
