Refuse-derived fuels (RDF) are fuels made from waste that replace primary fuels in thermal processes in the primary industry or in the field of energy transformation. The greatest challenge in the production of refuse-derived fuels (RDF) lies in the inhomogeneity of the waste streams to be treated. These can be divided into two groups according to their processing requirements: Firstly, types of waste that are already collected as a mono-fraction at the point of generation and can be co-incinerated without extensive treatment efforts. Secondly, waste streams with a high calorific value from commercial waste pre-treatment plants, waste sorting plants, etc. or fractions with a high calorific value after mechanical and aerobic/anaerobic biological treatment.
The materials processed in our systems mainly come from the second group, including household waste and production-specific commercial waste, residual waste from industry and commerce, construction site waste, thermal insulation composite systems, bulky waste and sorting residues. Depending on the processing width and depth required, different Doppstadt components are used, such as pre-shredding or fine shredding and separation, to ensure that the relevant requirements are met. The end result is always an output in the desired material quality.
