LafargeHolcim in the US, Geocycle achieves a major circular economy milestone with CenterPoint Energy to recycle 6 million tons of thermal coal ash from landfills

CHICAGO–(BUSINESS WIRE) – LafargeHolcim in the US, its subsidiary Geocycle and CenterPoint Energy, Inc. (NYSE: CNP) today announced a major milestone in their multi-year initiative with the first ship delivery of steam coal ash as part of a project that will be used to reclaim and recycle more than six million tons of coal ash lead to beneficial reuse in cement production.

LafargeHolcim, the country’s largest cement producer, Geocycle, a provider of sustainable waste management solutions, and CenterPoint Energy, which operates two coal-fired power plants in southwest Indiana, together invested over $ 80 million in infrastructure to remove, process, and transport, store and recycle Coal ash produced at CenterPoint Energy’s AB Brown power plant in Evansville, Indiana, for use in LafargeHolcim’s flagship cement plant in Ste. Genevieve, Missouri – Reducing the use of natural materials such as clay and sand in the cement plant.

“This milestone is a tangible example of how industry participants can work together to develop creative and efficient solutions that contribute to the circular economy. Together, LafargeHolcim, Geocycle and CenterPoint Energy will avoid landfilling power plants and reduce the consumption of non-renewable raw materials. This is a clear win-win situation for people and our planet, ”said Toufic Tabbara, CEO of US Cement at LafargeHolcim in the USA.

The teams recently achieved the first ship shipment of nearly 2,000 tonnes of the processed material – which contains mostly bottom ash with some fly ash – from the 165-acre pond at CenterPoint Energy’s AB Brown facility. Geocycle has led the ongoing initiative between LafargeHolcim and CenterPoint Energy since 2009.

“Our multi-year initiative with LafargeHolcim and Geocycle was ideal because it allowed the material to be removed from the environment and used for beneficial purposes,” said Steve Greenley, senior vice president, Indiana Electric Operations, CenterPoint Energy. “CenterPoint Energy’s decision to recycle the coal ash has reduced its environmental impact and allowed a choice with less financial impact than other compliance options.”

Used as fuel for a quarter of all electricity in America, coal creates two types of incineration waste: fly ash and bottom ash, a sandy sludge. According to the American Coal Ash Association, only 52% of the 78.6 million tons of coal ash produced in electricity generation was usefully reused in 2019. The rest – 37.6 million tons – was disposed of in landfills or retention basins. There are more than 2 billion tons of landfilled ash in the US. To mitigate environmental risks, federal regulations mandate the closure of ash ponds and encourage recycling of materials for environmental and economic benefits.

Through careful material sourcing and testing, this initiative promotes the treatment of accumulated coal ash material for beneficial reuse in making more environmentally friendly concrete mixes. This processing technology, which included trials with CenterPoint Energy’s pooled coal ash, is used in select markets that are experiencing a shortage of fly ash due to the ongoing shutdown of coal-fired power plants in the United States.

“This significant circular economy relationship with CenterPoint Energy is a striking example of how our geocycle recycling management business is looking for innovative solutions to transform our country’s ecosystem challenges into opportunities that add value to our operations and our leadership commitment to a net zero – Driving the future forward. “Said Sophie Wu, director of Geocycle North America.

Since 2009, Geocycle has been delivering nearly 1.5 million tons of dry fly ash waste from CenterPoint Energy’s AB Brown, FB Culley and Warrick power plants for beneficial reuse at the Ste. Geneva cement plant. This inland shipping represents the next phase in the long-term cooperation between the companies.
