Nalco Mobotec Announces Joint Venture With SONIC to Develop Technology to Reduce Greenhouse Gases

Nalco Mobotec Inc., a global leader in combustion optimization and air improvement technologies, announced today that is had entered into a joint venture agreement with SONIC Technology Solutions Inc. of Vancouver, Canada to expand the use of fly ash from coal-fired power stations as a cement substitute. The joint venture company, SonoAsh LLC, will develop SONIC's SonoAsh process, which physically preconditions waste fly ash and reduces residual carbon. Successful development will lead to a fully commercialized process allowing waste fly ash to be used as a cement substitute or concrete additive.

"The SonoAsh solution is another offering in the suite of solutions provided by Nalco Mobotec to enhance our customers' operations and reduce their environmental footprint," said Eric Fischer, President of Nalco Mobotec.

"Production of cement contributes an estimated seven percent of global carbon dioxide emissions. North America and Europe selectively utilize high-grade fly ash but 65 percent of North America's fly ash is deemed unacceptable to the cement industry and ends up in landfills. Global cement demand approaches three billion tons annually and has grown rapidly in recent years. We are very excited about this technology's impact on reducing greenhouse gas emissions and increasing the bottom line for our customers."

Cement is one of the largest commodity industries in the world and is also one of the most energy intensive. High-grade fly ash, from the electric utility industry, is currently used in the concrete industry as a performance-enhancing additive or cement replacement. This practice can contribute significantly to global reduction of greenhouse gases by reducing the need to produce cement. The SonoAsh process turns low-grade waste fly ash into a valuable high-grade product with carbon credits for both the electric utility and cement industries.
