Waste derived fuels

Sapphire Energy Recovery takes a variety of waste materials from industry and transforms them for use as fuel that can be processed in cement kilns.

Before any material can be used as a waste derived fuel in a cement kiln it must go through stringent trials and testing processes overseen by the Environment Agency. 

Any fuel classed as a waste must also be used within the strict guidelines of the Waste Incineration Directive which sets clear limits for emissions.

Sapphire Energy Recovery’s technical and commercial experts work with waste producers and the cement industry to identify materials that are potentially suitable for fuel and guide them through the necessary processes. 

A number of materials are already classified as suitable for use as fuel within the cement industry, or are currently under trial.  They include:

• Processed sewage pellets (PSP)
  Made from the sludge that remains after sewage treatment.
  
  
• Meat and bone meal (MBM)
  A fine material produced by sterilizing meat and bone waste drawn from high street butchers, supermarkets, abattoirs and pet food makers. All constituents are subject to the Government's established stringent tests to ensure that they are BSE-free.
  
  
• Recycled liquid fuel (RLF)
  A high-grade blended fuel, produced to a specification, made from non-recoverable materials used in making everyday products such as screen wash, paint, printing ink and brush cleaners.
  
  
• Recovered fuel oil (RFO)
  Oil with a similar make-up to domestic heating oil made from filtered waste oils which come from activities such as car servicing.
  
  
• Solid recovered fuel (SRF)
  Made from a range of municipal, industrial and commercial wastes to a quality specification, once all other recyclable constituents such as paper and plastics have been removed.
