Revolutionizing Cement Production: Cutting Emissions and Costs with Innovative Technology

Cement production, especially of significant volumes, requires the burning of hundreds of millions of tons of fuel annually and is accompanied by the release of significant amounts of heat, CO₂, NOx and SO₂. This contributes to climate change on the planet.

Despite the fact that the annual volume of cement production consistently exceeds 4 billion tons, the volume of CO₂ emissions into the atmosphere by cement plants is about 1000 kg per ton of cement produced, which is billions of cubic meters of harmful gases annually. In addition, new plants are being built in China, India, Latin America and other developing countries, where CO₂ emissions are growing much faster - in proportion to the increase in cement production, which leads to an overall increase in CO₂ emissions in the cement industry. The proposed introduction of changes to the existing technology makes it possible to dramatically reduce fuel consumption and emissions of NOx, SO₂, CO₂ per ton of cement by reducing the content of Portland cement clinker to 25-30% by weight.

Then it turns into modified cement with a low clinker content while maintaining high construction and technical properties of the material and with an extended shelf life (from a 2- month period standard for Portland cement, to one year or more for cement produced using a new technology). The new technology also provides for a significant reduction in the cost of production.
