ABSTRACT:
A method for decomposing and disposing of asbestos compounds through the use of a two part chemical process. The first step in the chemical process involves the decomposition of asbestos through the use of sulfuric acid. The second step of the process involves the solidification of the products resulting from the decomposition step. The efficacy of the invention process is enhanced by the use of a lubricating agent, an accelerating agent, and a cementitious or pozzolanic substance. The asbestos treated with the invention process is decomposed and forms a solidified mixture which can be easily handled and safely disposed of at a disposal site.
