Solid Recovered Fuel (SRF) is distinct from RDF in that its quality as a fuel is far superior. It is typically used in processes that require a high quality, small particle size, high Calorific Value, low Moisture Content material – such as cement kilns and new-generation ATT plants.
Solid Recovered Fuels are covered by international technical specifications which set, amongst other parameters, the chemical and physical parameters of an SRF [1]
Whilst the data for the export of SRF from the UK is often reported within the overall Waste Derived Fuel/RDF statistics, there is increasing evidence of a proportional growth in SRF production and export in the context of a reduction in RDF export[2].
Typical differences in the key parameters of RDF and SRF mentioned above are broadly as follows:
| Parameter | RDF Example | SRF Example |
|---|---|---|
| CV | 11 MJ/kg | 18 MJ/kg |
| Moisture Content | 25% | 15% |
| Particle Size | 300mm | 40mm |
Increasingly the market is considering further refinement of SRF which has been made into a pellet for ease of storage, haulage, and introduction into a Cement Kiln, with some companies seeking to achieve End of Waste classification that would then enable the material to be used in other applications as a blended substitute for coal - an example of this is Subcoal [3].
