One of the main methods for utilizing waste is its use as an energy source. Waste is only suitable for use as a fuel if it has chemical energy content. This energy content depends most of all on the size of the (organic) combustible fraction and on the moisture content. To better employ the chemical energy contained in wastes, alternative fuels have been developed which are mixtures of different wastes. Refuse-derived fuel (RDF) or solid recovered fuel/ specified recovered fuel (SRF) is a fuel produced by shredding and mixing municipal solid waste (MSW) or industrial waste. RDF can be used in a variety of ways to produce electricity. It can be used alongside traditional sources of fuel in coal power plants. RDF can be co-incinerated in the cement kiln industry, where the strict standards of the waste incineration directive are met. That is, the desire to reduce total fuel costs through substitution of RDF for the normal fossil fuels, primarily coal, used in these facilities. Internationally, RDF has complied with Kyoto Protocol measures and is considered a renewable fuel.
