Assessment of the resource associated with biomethane from food waste

► The biomethane potential (BMP) assessment is dependent on the inoculum. ► BMP results improve with active inoculum, which is acclimatised to the substrate. ► BMP of food waste was found to be between 467 and 529 LCH4/kg volatile solids added. ► The resource of food biomethane is assessed at 2.8% of energy in transport. ► This assessment is predicated on source segregation of food waste.
