We all are aware of the fact that cement manufacturing causes environmental impacts by releasing carbon emissions, dust and noise. In an attempt to reduce the hazard caused by cement manufacturing to the planet, Civil engineers at Purdue University and the Indiana Department of Transportation are collaborating on green projects around the state. The projects include work to use a waste product from cement manufacturing for the “Fort to Port” project located east of Fort Wayne on U.S.
Under this project called cement kiln dust, waste product from cement like cement kiln dust could be used to replace 70 percent of the roughly 1 million tons of lime used on projects annually to strengthen soil so that it can support new pavement. It is anticipated that the project could save $300,000 annually by recycling the waste product. The kiln dust was tested in 2008 by using it to repair Pendleton Pike at Interstate 465 in Indianapolis, which showed comparable engineering results at lower cost. Recycling cement kiln dust and other waste products for highway projects can be seen as cost-effective and eco-friendly.
