Abstract Because of the depletion of fossil fuels and because of its increasing cost, waste has been used as alternative fuels in cement rotary kilns for several years. In order to fulfil the requirements of environmental protection and quality of the final product, it is necessary to understand and quantify the different processes occurring in the kiln. The aim of our work is to …

Cement industry generates various waste both in the form of solids (dust) as well as gases (CO2). This industry accounts for over 5% of global CO 2 emissions [1]. One of the by-products of cement manufacturing is the Cement Kiln Dust (CKD). CKD is created in the kiln during the production of cement clinker. The dust is a particulate
