SRF Manufacture is an alternative fuel produced by shredding and dehydrating solid waste, typically consisting of combustible components of solid waste, including paper, card, wood, textiles and plastic. It can be produced to a range of specifications to meet customer requirements.
‘We have used M&K on several Waste-to-Energy projects in the past and we will continue to use M&K for future projects. M&K have the technical knowledge, the products, the technology and service resources to qualify them as the number 1 Waste-to-Energy experts’. Jim Entwisle – LWR
The Potential of SRF
Impending landfill targets, the increasing depletion of fossil fuels and the need to improve the UK’s waste agenda, seems to point towards SRF manufacture being an area of great potential. When used in replacement of traditional fuels, Solid Recovered Fuel Manufacture is carbon neutral.
What is the difference between Solid Recovered Fuel (SRF) and Refuse Derived Fuel (RDF).
Confusion still exists within the industry as to the difference between Solid Recovered Fuel (SRF) and Refuse Derived Fuel (RDF), but the two are not the same. Solid Recovered Fuel is manufactured to a specification, whereas RDF is comparatively cruder. The specification is likely to vary depending on end-user requirements, but typically Solid Recovered Fuel facilities will rigorously process pre-sorted C&I waste to a homogenous shredded particle size of less than 30mm, with a moisture content < 15% and calorific value of 18-22MJ/kg.
Solid Recovered Fuel Manufacture
- The materials used to produce Solid Recovered Fuel pass through a series of shredders, screens, air classifiers/density separators and magnets.
- Inert materials, recyclable plastics and metals are extracted from the shredded material, leaving a mix of mainly non-recyclable paper, card, wood, textiles and plastic.
- Although a small proportion of these materials can be recycled the quality of these materials is compromised once they enter the residual waste stream and recovering energy from these materials is currently the best environmental option.
Solid Recovered Fuel Manufacture may involve some but not all of the following steps;
- Preliminary liberation/sorting
- Course, pre-shredding
- Size screening
- Magnetic separation
- Refining separation
- Fine, secondary shredding
