Colosse Cement Company produces and supplies high quality cements to projects all
over the Midwest, and has done so for decades. Ranking among the premier cement
producers, Colosse has remained in compliance with government restrictions since its
establishment. Providing a high quality product to consumers at a low cost, without
sacrifices to environmental safety is a key part of Colosse’s mission. However, recent
regulations proposed by the EPA on kiln emissions and the classification of carbon
dioxide as a harmful gas regulated by the Clean Air Act have forced Colosse to re-
evaluate cement production and eliminate inefficiencies that contribute to harmful
emissions. Restrictions on kiln emissions are predicted to cost the cement industry up to
$684 million in the first year if companies are not compliant. With the severe
consequences of new regulations, Colosse’s survival as a cement producer requires a
On October 12, 2009, I proposed to research green cement technology as a solution for
adherence to recent legislation and optimization in cement production. Peter Epaphras,
head of Research and Development for Colosse approved the research three days later on
October 15, 2009, allowing the research to begin. The report focuses on these main areas:
1) Investigate the government regulations on cement production presently, as
well as future regulations.
2) Research the characteristics of green cement technology.
3) Explore the optimal location for green cement production in the United States.
4) Review the costs associated with OPC and green cement technology.
The most important benefits offered by green cement technology are its decrease in
carbon emissions and energy use. Green cement technology’s main focus is the
elimination of harmful outputs during production, which also decreases the cost of
production. In current applications, green cement technology has even increased the
carbon capture rate to .75 tons of carbon dioxide per ton of cement (13). The decrease in
energy use conserves natural resources, decreases harmful outputs, and decreases costs.
The optimal location of green cement technology relies on the proximity of production to
construction and demolition debris, SCMs, and carbon dioxide emissions. Each factor,
while located in different areas, lies in the same region of the United States. The Mid-
Atlantic region houses most of the nations C & D debris, carbon emissions, and SCMs,
which makes it the ideal area for production.
Many businesses have adopted the green mentality. In the cement industry, regulations on
emissions have forced many producers to develop new technologies and processes.
Calera, CeraTech, and Novacem are among the top cement producers employing green
cement technology. All companies are greatly decreasing energy input, using replacement
