Manufacturing of Solid Recovered Fuels (SRF) for Energy Recovery Processes

This contribution describes manufacturing processes and quality of three types of Solid Recovered Fuels – i.e. SRF low quality, SRF medium quality and SRF premium quality – that are used in energy recovery plants. In total, two case studies are reported. First case study is about the external processing and confectioning of non-hazardous household, industrial and commercial mixed wastes as well as the internal treatment and homogenisation of various waste fractions at the incineration plant for production of SRF low quality that is utilized in a Waste to Energy (WtE) stationary Fluidized Bed Incinerator. In the second case study, production of SRF medium quality and SRF premium quality that are used for substitution of primary fuels like coal and petrol coke in the cement kiln is described. Finally, data on SRF quality of all three investigated waste types will be summarized and discussed.

As already mentioned, SRF is a mixture of various non-hazardous waste materials from different sources (e.g. households, commerce and industry), that are under going distinct treatment and manufacturing steps like: multistage shredding, classifying, separation of Fe- and NON-Fe-metals, exclusion of heavy weight inert materials, as well as sorting out of unwanted materials like polyvinyl chloride (PVC) or of recycling materials like PET. The input waste materials that are treated in SRF processing plants can be described by their European waste code and description in accordance with the European List of Waste.
