What is SRF?

Solid Recovered Fuel, or SRF, is a higher quality alternative to RDF. The fuel consists of smaller fractions with a higher energy content. The higher calorific value means it is suitable for use in cement kiln facilities.

SRF Specification

  • Bales – plastic tied bales with a minimum of six layers of plastic wrap, 1 tonne bales measuring approximately 1.1 x 1.1 x 1.4m
  • Loose waste – processed waste collected loose
  • CV to be typically 15 – 22 Mj/kg
  • Fraction size to be typically <30mm

What is its use?

SRF waste is largely used across Europe to power cement kilns. Without the use of such a recovered fuel, the cement industry would no longer be a competitive or viable business.  SRF directly replaces fossil fuels such as Petcoke and coal, and offers an excellent environmentally friendly alternative.

How is it processed?

SRF follows a similar treatment process as RDF, however, the end of the process sees this material shredded to a much smaller fraction. The sorting process is also more thorough resulting in the waste ending up in a purer state than RDF.
