A possibility of thermal utilization of alternative fuels in cement industry is presented. The replacement of natural fuels with secondary materials in the process of organized waste recycling is the most significant step in this direction. One should emphasize the concept of "organized recycling", i.e. executed consciously and above all with the earliest possible segregation of initial secondary materials. Such segregation must not only lead to separate of different materials, but should also be applied to secondary materials for the production of alternative fuels. Only then it will be efficient as regards both environmental protection and economics. The goal of lowering production costs is one of two main factors stimulating activities aimed at replacing the natural fuel used in the cement production process with alternative fuels obtained from combustible wastes. The second factor is environmental protection, for instead of undergoing potentially hazardous storage; wastes can be duly treated and rendered harmless in a useful way, with the total consumption of their energy. Cement kilns, in which combustion processes reach temperatures up to 2000°C, are one of the several industrial installations ensuring the effective and environmentally friendly combustion of alternative fuels.
