Refuse Derived Fuel (RDF)
or Solid Recovered Fuel (SRF)
Refuse Derived Fuel (RDF) or Solid Recovered Fuel (SRF) is produced from waste after significant mechanical and often biological processing. SRF has to meet specific environmental and technical quality criteria in order to meet a European SRF quality standard. SRF and RDF and can be used for energy generation in some industrial applications, such as cement kilns. Alternatively it can be used in dedicated energy recovery facilities, such as gasification or pyrolysis plants.
Around 50-70% of the SRF mass produced by a specific UK MBT plant is of biomass origin, and can generate renewable and carbon-neutral energy. The proportion of biomass varies according to the MBT plant feedstock and processes used.
The processes used for SRF production are referred to as Mechanical Biological Treatment (MBT). Please see the European Recovered Fuel Organisation (ERFO) for further information.
