Refuse-derived fuels (RDF) are usually extracted from refuse and serve as an alternative to well-known fossil fuels. They come in solid, liquid or gaseous form and their processing differs according to their intended usage (Saubermacher, 2018).
Apart from waste incineration, many industrial plants already utilize processed waste materials as a fuel substitute on a considerable scale. In addition to the ecological advantages, such as the destruction of organic pollutants, the separation or accumulation of inorganic pollutants and the reduction of climate-relevant emissions, costs are saved and dependence on imports among the primary energy carriers also decreases. An added benefit emerges when the incineration residue is recycled in the same process. (BAWP 2017)
