cement industry has been using large quantities of waste fuels or biomass fuels, for more than 15 years. The production of cement involves the consumption of large quantities of raw materials, energy, and heat. Cement production also results in the release of a significant amount of solid waste materials and gaseous emissions.
Our science-based target will further specify our new ambitions on reducing the carbon footprint to play our part in keeping global temperature rises well below 2°C and thus future-proof our business. Further, to insulate our group from physical risks of climate change, we took a challenge in 2014 to become a water positive cement group.
Today, the cement industry provides a significant contribution to the waste management practices of many countries. The responsible use of waste as an alternative fuel to heat cement kilns is lowering the industry's consumption of fossil fuels, which is helping to reduce the environmental footprint of global cement production. 20%

The environmental impact of concrete, its manufacture and applications, are complex.Some effects are harmful; others welcome. Many depend on circumstances. A major component of concrete is cement, which has its own environmental and social impacts and contributes largely to those of concrete.. The cement industry is one of the primary producers of carbon dioxide, a potent greenhouse gas.
May 09, 2012· Cement Emissions. The production of cement releases greenhouse gas emissions both directly and indirectly: the heating of limestone releases CO 2 directly, while the burning of fossil fuels to heat the kiln indirectly results in CO 2 emissions. The direct emissions of cement occur through a chemical process called calcination.
Cement Production. Cement production is an energy intensive industrial process that requires heat to be supplied at high temperature levels under the constraints of gas-solid heat exchange phenomena and the kinetics of chemical reactions.
