Ash Grove Cement’s AGem Program

Ash Grove’s AGem Initiative is an aggressive energy reduction process to reduce thermal energy use by 17 percent per metric ton of clinker produced and reduce electrical energy use by 10 percent per metric ton of cement produced.

We will strive to accomplish these targets in 2012 by renewing our “Back to Basics” process engineering program through:

• Striving to increase our use of alternative fuels and raw materials
• Formulating our cement chemistry to use less thermal energy
• Installing electrical monitoring and measuring equipment
• Coverting to more efficient motors and lighting
• Reviewing our electrical usage and turning off lights and equipment when not needed
• Using state-of-the-art technology when we rebuild our facilities

In 2007, Ash Grove’s specific gross CO2 emissions were 885 kg per metric ton of cementitious material, which is an 11 percent reduction from our 1990 specific gross emissions. In 2004, Ash Grove Cement Company committed itself to sustainable development when it became the only U.S.-based cement company to join the World Business Council for Sustainable Development’s Cement Sustainability Initiative.
