CEMEX, S.A.B. de C.V. (“CEMEX”) (NYSE: CX) announced today a collaboration agreement with the Earth Engineering Center (EEC) of Columbia University and The City College of New York. The EEC will conduct a year-long study of the life cycle effects of using alternative fuels in cement manufacturing. This study will result in a better understanding of the role that alternative fuels play in society and the environment.

Since 2005, CEMEX has invested more than US$ 175 million, adjusting its production process and installing equipment to use alternative fuels in its cement kilns. In 2012, CEMEX achieved an alternative fuel substitution rate of 27% in its cement production, and is on track to reach its target of 35% by 2015.

“This collaboration with EEC underscores the urgency of finding alternative fuels given the continuous rise in oil prices and the increase of waste in landfills,” said Luis Farias, CEMEX's Senior Vice President of Energy and Sustainability. “Through its alternative fuel strategy, CEMEX has reduced its CO2 emissions by approximately 2.5 million tons per year.”

Led by Professors Nickolas Themelis and Marco Castaldi, from Columbia University and the City College of New York, respectively, the study will focus on waste combustion technologies implemented in CEMEX kilns in the United States and Mexico.

“The study is of great interest to the EEC because cement production is the largest materials-based high-temperature process worldwide, therefore, cement kilns present a great potential to reduce the amount of wastes in landfills,” explained Professor Themelis. “This study provides EEC with the opportunity to develop a knowledge position similar to the one EEC has attained in the global waste-to-energy technology and industry.”

The substitution of fossil fuels results in additional benefits such as the reduction of GHG emissions and lower energy costs.

About EEC

The principal focus of EEC research is sustainable waste management and in particular the recovery of energy and materials from solid wastes. Some key EEC accomplishments include the BioCycle-Columbia bi-annual survey of waste generation and disposition in the U.S., three books on waste-to-energy, and over one hundred theses and technical papers on various waste management subjects.
