Refuse Derived Fuel (RDF) is actually a fuel made from the organic contents of waste, usually municipal solid waste (MSW).
MSW, which is waste thrown away by households, comprises two distinct portions: organic and inorganic waste. Organic waste include plastics, kitchen and food waste, paper, rubber etc., while inorganic waste include glass, metals etc.
The organic portion of MSW can be used to recover energy – which can be used for heating or for electricity.
Typically, the organic portion of the MSW is segregated and is made into a briquette type material. Such a material is called RDF. RDF can be used in furnaces, boilers and more to generate heat, in the place of coal or biomass.
