The analysis of the current state and existing environmental problems of cement industry in Russia and Ukraine and the ways to solve them as due to changes in production technology of Portland cement, and by utilizing the waste gases from the clinker burning. The main component of emissions from cement kilns is carbon dioxide, which can be utilized. The new technology of recycling carbon dioxide contained in the emissions of cement industry, which includes the steps of purification of gases from cement dust, carbon dioxide emission through the use of highly compact vortex apparatus and recycling to produce effective fertilizer - ammonium bicarbonate, which has better performance compared to the traditionally used in agriculture economy of ammonium nitrate. The technological scheme of the process of separation carbon dioxide gas and production of ammonium bicarbonate worked out.
