Coal ash is the secondlargest waste material in the behind trash. Utility companies and the ash management firms working for them struggle to find economic ways to get rid of it.
#0183;#32;Battelle aims to validate the economic viability of recovering REEs from coal ash using its patented (U S) closed loop Acid Digestion Process (ADP). This validation will be accomplished by selecting a source of coal ash that consistently provides concentrations of rare earth elements above 300 parts per million by weight and in a
#0183;#32;One of the big issues propagated by the coal burning utility industry is that regulating coal ash waste as a hazardous waste would hurt the market for recycling of coal ash.
Coal ash is a nonhazardous material created when coal is burned to produce electricity. Recycling is the only way to avoid permanent disposal of the material. However, much of the ash stored in basins has too much carbon to be used in concrete products.
About Coal Ash Recycling. Coal is the fuel source for approximately onethird of electricity generation in America and produces large volumes of solid coal combustion products primarily ash and synthetic gypsum from emissions control devices. There are many reasons to view coal combustion products as a resource rather than a waste.

Recently, prices of strategic minerals and rare earth elements have risen dramatically due to global supply shortages and increasing demand.
The North Carolina Coal Ash Management Commission staff in a June report recommended that among the recycling options the greatest opportunity relates to the use of coal ash in producing concrete. The technology curve for recycling coal ash, rather than

#0183;#32;By Casey Mann, Chatham News + Record Staff. Duke Energy is constructing a coal ash recycling unit on the property of its former Cape Fear plant
In a project managed and cofunded by DOE Fossil Energys National Energy Technology Laboratory (NETL), an industry/academic research partnership has taken a significant step toward developing a pilotscale test facility for creating a more effective way to harvest rare earth elements (REEs) from coal ash a byproduct of coal combustion, created when coal is burned to generate energy.
#0183;#32;According to the American Coal Ash Association, in 2014, 50,422,238 short tons of fly ash were produced in the United States alone. Its worth noting that while fly ash is predominantly a byproduct of coal power production, it can also be produced from other power sources, such as wood and biomass fuels, though to a lesser degree.
#0183;#32;New Jersey based waste to energy firm, Covanta Holding Corporation (NYSE: CVA), has commenced construction of its first Total Ash Processing System (TAPS) in Fairless Hills, Pennsylvania, adjacent to its existing metals processing facility. The company said that the first TAPS plant is designed to process over 400,000 tonnes of ash from multiple Covanta waste to energy facilities, recycling
2 #0183;#32;Coal Ash Recycling: A Rare Opportunity Strategic materials such as rare earths are increasingly vital. With supplies tight, could new technologies open up fresh supplies by recycling the abundant and potentially hazardous wastes produced by the combustion of coal?
1 #0183;#32;Fiftytwo percent of the coal ash produced during 2019 was recycled, leading to an overall 31 percent decrease in recycling activity. As coal ash production declines, declining use in applications with lower economic value represents a lost opportunity to create significant environmental benefits.
