Beneficial use is the recycling or reuse of coal ash in lieu of disposal. For example, coal ash is an important ingredient in the manufacture of concrete and wallboard, and EPA supports the responsible use of coal ash in this manner. This final rule supports the responsible recycling of coal ash by distinguishing beneficial use from disposal.

Coal is primarily used as fuel to generate electric power in the United States. In coalfired power plants, bituminous coal, subbituminous coal, or lignite is burned. The heat produced by the combustion of the coal is used to convert water into highpressure steam, which drives a turbine, which produces electricity. In 2019, about 23 percent of all electricity in the United States was ...

Coal production continues to grow globally due to the demand for low cost energy and iron and steel, as well as cement. Coal, based on the current extraction rates, will last about 115 years longer than conventional oil and gas reserves, with an estimated trillion tonnes of proven coal reserves worldwide. Ten countries are responsible for 90% of the total global coal production.

The Imported Coal Based (ICB) power plants had imported coal of more than 45 MT per year from 201617 to 201920. However, coal import by the ICB power plants dropped to the lowest level of MT in 202122 and the generation from these plants also dropped to billion units (BU) in the year 202122 as compared to the 100+ BU which these plants have been generating since quite some time.

How a Coal Plant Works. Coalfired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over. Here's a real ...
