ABSTRACT:
A method of immobilizing or stabilizing lead paint contaminated construction or demolition debris in which the debris is shredded, mixed with water and a chemical, such as fly ash, lime, Portland cement or kiln dust. The treated debris is then collected and allowed to stand for a period of time sufficient for the lead paint to be converted from a soluble form to an insoluble form. Excess water may be drained and collected and the treated and lead paint stabilized debris disposed of.
