Solid Recovered Fuel (SRF) Services
Solid Recovered Fuel (SRF) is a product of the Mechanical Biological Treatment (MBT) process which treats a proportion of household waste, that cannot be recycled, to produce a specialist fuel product with a high calorific value.The MBT process uses naturally occurring heat from the biological degradation processes to dry the SRF product. No external heat source is needed, hence this reduces the energy intensity of the process.Solid Recovered Fuel
Recycling and Reuse
The DEFRA 2010/2011 Local Authority Collected WasteManagement Statistics for England revealed 58.8% of all household waste is not being recycled. This 14 million tonne waste mountain, equivalent to 264 kg per person, contains high calorific material that can be converted to Refuse Derived or Solid Recovered Fuel.
Generally SRF has the energy (calorific content) equivalent of 2/3rds that of coal
The UK has the potential to produce 9 million tonnes of SRF each year, the equivalent to 6 million tonnes of coal. Around 60% of the energy of SRF isderived from carbon neutral biomass.
Quantifying the benefits
Using one tonne of SRF instead of the equivalent of primary fuel: coal displaces 0.67 tonnes of coal in a cement kiln has a net benefit saving of approximately 1 tonne of CO2e. So Shanks, by manufacturing approximately 88,000 tonnes of (cement grade) SRF in 2011, is saving 88,000 tonnes of CO2e each year.
This is the equivalent to: The equivalent emissions from driving:263 million miles
Enough CO2 to fill:136 billion cans of coke
187 million wheelie bins
7.3 million builders skips
30 millennium stadiums
