RDF (Refuse-derived fuel) or SRF (solid recovered fuel / specified recovered fuel) is waste from households, where SRF meets an international standard and is becoming a more interesting fuel. Governments are increasing fees for landfill, which makes the fuel interesting as it is considerably cheaper than other biomass.
Together with a customer we have tested SRF over a long period of time, and generally SRF is a difficult raw material to densify – with higher opex and capex costs than normal biomass. It is C.F. Nielsen’s recommendation that SRF should be mixed with another raw material such as demolition wood, because this will increase the capacity of the machines and lower the costs. A diameter of 60 mm or above will increase capacity even more.
SRF generally has higher moisture than 16% and a high degree of impurities. It is essential that the right preparation takes place before briquetting the material
SRF briquettes are ideal for gasification or power plants.

In the U.K. there is a large market for producing and selling bedding for horses. Most of the bedding is made from shavings from softwood. The shavings have to be clean from dust, so the dust is removed during the processing of the shavings.
One of our customers in the U.K. has decided to utilize the left over dust from the production of shavings to produce briquettes for consumers.
