The range of alternative fuels that may be used in cement production is extremely wide and diverse, including materials like waste oils, plastics, auto shredded residues, waste tyres, sewage sludge and all kinds of slaughterhouse residues. However, to the moment only small volumes (10 - 20%) of the fuel requirement are achieved though in some advanced installations percentages of 80% and more are reported (tyres or petcoke).
The main problems are related to technical constrains regarding ignition and burn out properties, particles size and built-up of volatile compounds. A number of innovative solutions have been developed by engineering companies to address these problems and pave the way for polygeneration with the use of alternative fuels and secondary raw materials in cement industry. They have been demonstrated in two case-studies in Norway and Hungary. The proposed project has been designed to disseminate technical knowledge and experience from the implementation of these solutions.
