Biomass conversion to biomethane in the reference maize-anaerobic digestion (AD) scenario. Different steps of biomass conversion to biomethane in an AD plant, including inputs (biomass and electricity) and outputs (biomethane, digestate, and methane losses). Digestate (i.e., solid and liquid digestates) was circulated within the system to the soil as a plant fertilizer
