Apr 13, 2016· Though the white block's production still requires some of the CO2-emitting fuel use of typical cement making, CO2 is also one of the ingredients used to create it. About one-third CO2 by mass, the cementlike substance reduces its carbon footprint .
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.

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.
Indian Cement Industry is the second largest cement producer in the world after China with a total capacity of 151.2 Million Tonnes (MT). The Indian cement industry is dominated by 20 companies, which account for almost 70% of the total cement production in India.
