Biomass fuel Biomass is a generic term for organic material derived from plants or plant derived materials used to produce heat, electricity or transport fuel and is regarded as being less carbon-intensive than fossil fuels. Biomass as a fuel for power/heat generation projects involves using biological material from, for example: • waste and clean/recycled wood, eg forestry residues, landscaping remains and wood chips.(waste wood is graded A, B C and D by reference to the Wood Recyclers Association grading table: Grade A – pre-consumer waste wood and wood packaging (clean/untreated), Grade B – Industrial waste wood – (treated/non-hazardous), Grade C – Municipal Waste Wood – Treated/non-hazardous; and Grade D – Hazardous waste wood • specifically grown energy crops that are grown to be converted into energy, including maize, grass, miscanthus (elephant grass) • residues from forestry/agriculture To be economically viable, the developer of a generation plant using biomass as its principle fuel source should have in place one or more reliable biomass fuel supply agreements. Exclusivity of supply can assist with viability of a biomass generation facility.
