RDF is a kind of alternative solid fuel, which is derived from
recyclable materials municipal or industrial solid wastes, such as
plastics or from materials that are hard to recycle after decomposing.
Refuse-derived fuel typically consists of pelletized or fluffy
MSW that remains after the removal of noncombustible materials
such as ferrous materials, glass, grit, and other noncombustible
materials. The remaining material is then called RDF and used in
clinker production as a secondary fuel. However, the environmental
concerns of incineration also apply to RDF combustion facilities.
The limit values for some pollutants are the same for cement and
combustion plants. There are significant differences with respect
to some pollutants. (Gendebien et al., 2003).
