What is Refined RDF?
Refined Refused Derived Fuel sits between RDF and SRF. Still a fuel produced from a range of waste, including municipal, commercial and industrial waste, yet processed to a greater extent than RDF. Where RDF fraction size is typically <300mm and SRF is <30mm, Refined RDF is around 100mm, and as such has a lower moisture level with a higher calorific value (CV).
Refined RDF is suitable for Circulating Fluidised Bed (CFB) boilers that tend to require a more refined product than a typical EfW plant.
Refined RDF Specification
- Bales – plastic tied bales with a minimum of six to eight layers of plastic wrap, 1 tonne bales measuring approximately 1.1 x 1.1 x 1.4m
- Processed waste collected loose
- CV to be typically 12 – 16 Mj/kg
- Fraction size to be typically <100mm
What is its use?
Refined RDF is incinerated in CFB facilities across the UK and Europe, in order to generate energy to produce electricity and heat for the local area.
How is it processed?
When Refined RDF is produced, the easily recycled material is first removed, such as wood, paper, plastics and glass. The remaining waste, which is either unable or uneconomical to be recycled, goes through further processing to reduce the chlorine and sulphur contamination. It is then shredded to 100mm and baled and wrapped for transport.
