New York based Ash Improvement Technology Inc (AIT) signed an agreement for
implementation of its CleanCem™ ash treatment process at a coal-fired power plant
located in the State of Chhattisgarh, India.
This is AIT’s first operation in India, with an expected production of over 350,000 tons of
treated ash per year.
Coal-fired plants have been in the spotlight both in the US and abroad, spurring much
debate about coal ash disposal methods and contaminants leaching into groundwater
tables and affecting public health. China, India and the US generate more than two
thirds of the world’s ash, a whopping 600 million tons every year.
The CleanCem™ process developed by AIT treats ash while it is formed, and converts it
into a beneficial material via introduction of proprietary additives in the boiler system.
Ash chemistry and mineralogy are modified in the process to attain the performance of a
high value cement substitute.
“By using the boiler as a chemical reactor for our process, we not only avoid the cost of
shipping waste ash to an off-site treatment facility, but we also control the quality of the
end product in real time”, said Wayne Fried, AIT’s Chief Technology Officer. “In boiler
operations, where fuel and other conditions often change, the ability to maintain a
consistent performance of our ash -based cement replacement is a clear advantage.”
Indian coal has ash contents as high as 45%, and large piles of unused waste prompted
authorities to enact new regulation. Operators of coal-fired plants must ensure that 100%
of ash is used beneficially by 2014. AIT is well positioned to offer the market a practical
According to Marc Zacharias, President and CEO, “Now is the right time for AIT to enter
the Indian market”. “We are impressed with India’s dynamic business environment and see an opportunity to make an impact in a country with sustained growth in the
construction sector and a heavy reliance on coal power”.
