between heavy metals that are or have a species that are volatile (in other words Hg, Tl) 

and those which are non-volatile (for example Cr, As and Ni). A third group includes 

metals that are or have compounds that are semi-volatile (Sb, Cd, Pb among others). [29]

Non-volatile heavy metals are bound in the solid phase by more than 99 percent  

[12, 19], for example in clinker. Due to of different gas and dust treatment facilities (for 

example, bag filter or ESP) and/or separation processes (for example chlorine bypass) 

operated in the cement industry, there is generally no exact connection between input 

fuel concentrations and emission level of most heavy metals. [29]

As shown in Figure 10, the emission of pollutants by co-incineration plants like cement 

kiln can be related to the input materials, the process conditions and the plant itself. 

To minimize negative impacts on environment, legal control regimes are defined for 

co-incineration plants.
