May 14, 2020For example, one start-up uses a lower proportion of limestone in its cement, which results in fewer process and fuel emissions; this company's process also locks in additional CO 2, which is added before the concrete cures. Adding CO 2 makes the concrete stronger and reduces the amount of cement needed.

May 09, 2012Indirect emissions from burning fossil fuels to heat the kiln can be reduced by switching to alternative fuels, including natural gas, biomass and waste-derived fuels such as tires, sewage sludge and municipal solid wastes. These less carbon-intensive fuels could reduce overall cement emissions by 18-24 percent from 2006 levels by 2050.
