The co-processing of alternative fuels provides a solution in terms of reducing fossil fuel dependency as well as a contribution towards the lowering of emissions. The use of alternative raw materials also has numerous benefits, including a reduced need for quarrying and an improved environmental footprint of such activities. The use of alternative materials in the cement industry lowers global CO2 emissions and does not have a negative impact on production process emissions or on the environmental and technical quality of the final product. This report gives an overview of the possibilities and status of these technologies in Europe.
