At present, the production of so-called substitute fuels from waste and renewable raw materials and the utilization of these fuels in high temperature production processes, for example in the steel and cement industry as well as the chemical industry, is of increasing interest [e.g. 1-9]. In addition to the energetic utilization (substitute fuel), the material utilization (the ash) can also play a role. In both cases, the boundary conditions of the production processes (performance, process temperature profile) must of course be weighed equally along with the properties of the substitute fuels, as is case with application of conventional fuels. Additional points of view must also be considered when regarding the utilization of substitute fuels, in particular the comparative evaluation (energy exchange ratio for the substitution of the regular fuel, etc.) as well as the correlation of cumulative energy and pollutant balances.
