Under the terms of the agreement, Sika has also made an investment to take an equity stake in AIT.

The manufacturing process of cement releases CO2 into the atmosphere, at a rate of 850kg of CO2 for each ton of cement produced, thereby accounting for a total of 5% of the world’s CO2 emissions.

AIT president and CEO Marc Zacharias said coal ash is a perfect material to substitute clinker, hence reducing CO2 emissions inherent to cement production, and the environmental toll of large ash disposal sites.

AIT’s proprietary technology treats coal ash while it is formed within the power plant.

The result is an end product that offers flexibility in production that allows for performance levels tailored to a number of end use applications.
