Co-processing is the use of waste as raw material, or as a source of energy, or both to replace natural mineral resources material recycling and fossil fuels such as coal, petroleum and gas energy recovery in industrial processes. The co-processing of waste in the cement industry provides a maximum substitution of non renewable materials.

Mercury enters in the cement manufacturing process as a trace element with the raw materials and the fuels. The mercury content of natural raw materials varies between individual raw material deposits and even within the same deposit. In fuels, the amount of mercury can vary in a similar way, depending on the fuel type and the fuel source.
