CTS Cement Manufacturing Corporation | Rapid Set® is committed to operating in an environmentally responsible manner. We manufacture cement in a conscientious manner to minimize CO2 emissions, protect natural resources, reduce waste, and reduce potential environmental and health hazards. It is our practice to assure the environmental integrity of our processes and facilities. As part of ongoing efforts to sustain the environment, CTS Cement commits to the following initiatives:
Reduction in Wastes
CTS Cement uses as raw materials, wastes from aluminum recycling and by-products from the production of various chemicals, such as synthetic calcium sulfate. By using by-products from the recycling of aluminum, we prevent such wastes from being released into the environment.
Protection of Natural Resources
By being part of the aluminum cycle, CTS Cement helps reduce the need to extract alumina from the ground. Recycling aluminum generates 95% less air pollution and 97% less water pollution than producing aluminum from bauxite ore. In addition, making aluminum from bauxite requires the production of petroleum coke, soda ash, and lime — all extracted from the ground. It also causes the emission of carbon dioxide and other air pollutants. It also generates wastes such as red mud that require treatment and disposal. The use of synthetic gypsum also decreases the need to extract gypsum from the ground.
Reduced Carbon Emissions
Cement is made by heating limestone with other materials in a kiln. The resulting hard substance, called “clinker”,
is ground with a small amount of gypsum to make the cement. Rapid Set® is more environmentally friendly than portland cement for three main reasons:
1. Rapid Set® is made at lower temperatures, which means that its processing requires less fossil fuel.
2. Rapid Set® requires less limestone per ton, thereby reducing CO2 emissions.
3. Rapid Set® has longer lifetime than portland. In pavement tests conducted at the Seattle/Tacoma International Airport by Construction Technology Laboratories, Inc. (CTL), the lifetime of Rapid Set® concrete was found to be twice as long as that of Portland concrete.

Taking the cumulative effect of these three factors into account, the carbon footprint of Rapid Set® cement is just 32% of portland cement.
The amounts of CO2 released into the atmosphere per 50-kg bag of cement are:
• 10.5 kg. CO2 for Rapid Set®
• 30 kg for portland
Cement Production Plants
We monitor the operations of our cement production plants to ensure compliance with federal and state regulations, as well as professional standards of good industry practices. Our technologies and operating procedures are designed to minimize health and safety risks. We provide a safe working environment, and ensure that employees are properly trained and have the right safety and emergency equipment.
