Refuse-derived fuel (RDF) and solid recovered fuel (SRF) are solid fuels made from non-hazardous waste which are used to produce energy.
The processes used to produce RDF and SRF must ensure that they comply with the specifications and classifications laid out in the standard NF-EN-15359.
This standard provides for the classification of RDF and SRF based on an economic criterion (their LHV, or Lower Heating Value), a technical criterion (their chlorine content) and an environmental criterion (their mercury content).
