Journal of Environmental Quality Abstract - Environmental ...

Coal combustion residues account for 90% of all fossil fuel combustion wastes produced in the USA. It is projected that by the year 2000 more than 150 million t of these materials will be produced in the USA each year. Presently, only about 20% of these wastes are utilized, with the remainder deposited in landfills or surface impoundments.
