Environmentalists generally support use as a way to keep coal ash out of leaking ponds, but say more oversight and regulation are needed to make sure that reuse isn't exposing people to toxic metals. Proponents note that there are no examples of coal ash reuse causing harm since the federal coal ash rules were adopted in 2015.

This paper studied the gasification kinetics of char derived from Victorian brown coal (VBC) in a fluidized bed reactor which mimics the fuel reactor conditions of a chemical looping combustion process. Mass of char, char particle size, and gas flow conditions were optimized to ensure the gasification reaction free from mass transfer limitations.

Recycling coal ash for concrete is practical and safe, but excess carbon in the ash must be removed before it's suitable for reuse. In most cases, coal ash is between 6% and 15% carbon, which is too high to meet specifications for concrete. The STAR unit reduces the carbon level below 1%. Julie Olivier

Coal is a combustible sedimentary rock formed from vegetation that has been consolidated between other rock strata and altered by the combined effects of pressure and heat over millions of years. Coal is composed primarily of carbon, and also contains varying amounts of other components, like hydrogen, oxygen, sulphur and other impurities.

A channel of uniform cross-section is cut manually into the coal seam, and all the coal within the cut section is collected on a plastic sheet placed at the base of the channel. Most channels are around 1.0m across and samples should not be less than 15kg per meter of coal thickness.

Regardless of the type of dust collection, an automatic system can convey dust away, whether pneumatically or on a belt, to a combustor. Another option is for dust to be collected in a bin or super sack to be hauled away. In addition to these design measures, proper housekeeping is critical for safe operations at a coal facility.

When pulverized coal is burned in a slag-tap furnace, as much as 50 percent of the ash is retained in the furnace as boiler slag. In a cyclone furnace, which burns crushed coal, 70 to 85 percent of the ash is retained as boiler slag (NETL 2006).
