Calculation of carbon dioxide emission during the production of magnesium binders from magnesium-containing rock

The article discusses the environmental effectiveness of the production of magnesium binders based on mining waste using the technology of intensified roasting. The importance of the transition to technologies with reduced carbon dioxide emissions into the atmosphere is substantiated. The main devastating consequences caused by an excess of carbon dioxide from a global and local point of view are described. The calculation of emissions of carbon dioxide due to thermal decomposition of charge carbonate minerals is given. The calculation of emissions of carbon dioxide as a product of combustion of fuel for a burning plant is presented. The process of release of gases from the charge during the thermal treatment of dolomitic rock is studied, the absence of release of gases containing chlorine from intensifier additives is established. The carbon footprint of the technology of magnesium binders is compared to the technology of Portland cement production. The conclusion about the relevance of the partial replacement of Portland cement with an alternative environmentally effective magnesium binder in the production of building materials is made.
