Biomass conversion to biomethane in the willow pyrolysis scenarios. Different steps of biomass conversion to biomethane in a pyrolysis plant including inputs (biomass and electricity) and outputs (biomethane, biochar, heat, and methane losses). In willow scenario a, the biochar was circulated within the system as a soil amendment. In willow scenario b, the biochar was exported from the system for use as an energy source
