CERATECH Inc (CTI) claims to manufacture cement that utilizes 95% waste fly ash from electric utilities, dramatically reducing their landfill requirements while generating zero carbon dioxide emissions from the cement production process. Cement industry is considered to be one of the largest emitter of carbon dioxide.

CTI’s technology uses fly ash which is the by-product of coal combustion, dramatically reducing the volume of ash that is being land filled. About three of every five tons of ash produced—approximately 42 million tons a year—end up in a landfill. A ton of CTI “green cement” diverts approximately 1,800 pounds of landfill waste. An additional benefit of CTI’s unique technology is that its cement production process generates no carbon dioxide emissions adding to its attractiveness.

CTI’s cement is a replacement for portland cement, with outstanding strength and durability characteristics. With no other cement on the market composed of more than 90 percent fly ash, CTI’s green cement technology sets a new standard in meeting green construction guidelines, particularly the U.S. Green Building Council’s LEED certification requirements.

The single most advantage of CTI’s technology is the low carbon emissions and use of landfill waste to produce cement. At a time when cement industry is trying to reduce its carbon emissions, CTI’s green cement technology will go places. The Calera process that uses carbon dioxide to manufacture cement can complement CTI’s technology leading to reduction in carbon emissions from cement industry.

Alpha Natural Resources has made a strategic investment in CTI which gives it 10.3 percent of the equity in CTI on a fully-diluted basis with an option to increase that stake to 28.3 percent of the fully-diluted shares if certain criteria are met. The amount of Alpha’s initial investment was not disclosed. “Alpha’s investment is an ideal fit within our larger sustainability investments strategy,” said Michael Peelish, chief sustainability officer for Alpha Natural Resources. “We’re looking for ways to encourage development of new technologies that will bring sustainable environmental benefits to our utility customers. Conversion of waste fly ash into a green construction material represents an exceptional environmental use of coal combustion by-products.”

According to Jon Hyman, CTI CEO, “Alpha’s investment brings immediate benefit to CTI. Their strategic support—especially given Alpha’s excellent reputation in the industry—is an endorsement that we know will have great value in our discussions with leading U.S. utilities. Expediting the development of partnering agreements with leading utilities will result in our ability to expand our cement production and distribution capabilities. Also it will strengthen our ability to compete cost effectively against traditional cement companies.”
