The two largest forms of solid waste from coal-fired generation are coal ash (from the combustion of coal), and “scrubber” slurry (from environmental controls at the plant). Collectively, these two wastes are called coal combustion residues, or CCRs. CCRs are the second most abundant waste material in the United States, after household waste.

Waste-to-energy plant - Wikipedia

A waste-to-energy plant is a waste management facility that combusts wastes to produce electricity.This type of power plant is sometimes called a trash-to-energy, municipal waste incineration, energy recovery, or resource recovery plant.. Modern waste-to-energy plants are very different from the trash incinerators that were commonly used until a few decades ago.

Environmental impacts of coal - Global Energy Monitor

"Third, coal consumption is far more concentrated than the use of other fossil fuels. A mere six hundred large coal-burning power plants account for nearly all coal usage, in contrast to the tens of millions of cars, trucks, planes, homes, businesses, and factories that burn oil and gas. Thus, reducing emissions from coal is a far simpler task."

Waste heat - Energy Education

Waste heat is the unused heat given to the surrounding environment (in the form of thermal energy) by a heat engine in a thermodynamic process in which it converts heat to useful work.The second law of thermodynamics states that waste heat must be produced when converting a temperature difference into mechanical energy (which is often turned into electrical energy in power plants).
