CEMEX, S.A.B. de C.V. (“CEMEX”) (NYSE: CX) informed today that, since 2005, CEMEX has invested more than US$ 175 million, adjusting its production process and installing equipment to prepare, handle and feed alternative fuels into its cement kilns. In 2011, CEMEX achieved approximately a 25% alternative fuel substitution rate in its cement production, the highest rate among its global peers. The alternative fuel strategy has enabled CEMEX to avoid the use of close to 2 million tons of coal and the emission of 1.8 million tons of CO₂ into the atmosphere.

The following video explains the many advantages of using waste for fuel and how CEMEX is using alternative fuels in its cement kilns as part of its carbon strategy: http://goo.gl/ccbQI

The substitution of fossil fuels with alternative fuels result in numerous benefits such as:

• Reduces GHG emissions
• Saves fossil fuels for the future
• Reduces need for landfill
• Recovers energy from waste
• Decreases energy costs

CEMEX has set a target of a 35% alternative fuel substitution rate in cement production by 2015, and it’s on track to make it happen.
