ABSTRACT
Molecular Bonding System® for Heavy Metals Stabilization
Solucorp® Industries, Ltd.
Demonstration Bulletin
EPA 540/MR-97/507
September 1997
Solucorp® developed a patent-pending system to reduce the leachability of heavy
metals in soils, slags, and other solid wastes. Metal compounds are rapidly
converted to less-soluble metallic sulfides. MBS® utilizes proprietary chemicals
to treat the soil; soils can be excavated and treated in a pugmill or in situ
using soil mixing augers. The technology was demonstrated at the Midvale Slag
Site in Midvale, Utah. Three waste streams, contaminated with arsenic (As),
cadmium (Cd), and lead (Pb), were treated; approximately 500 tons of each waste
was treated. A second test of 500 tons of one waste was conducted by Solucorp
using EPA's protocol and oversight contractor. Toxicity Characterization Leaching
Procedure (TCLP) leachable Pb concentrations were reduced to below the regulatory
limit. TCLP As and Cd concentrations were below TCLP limits in untreated and
treated wastes. The mean volume increases in the treated wastes ranged from
4 to 16 percent. Process throughput averaged 52, 59, 56, and 61 tons/hour for
the four waste streams. Costs were estimated at $20/ton for 2 million tons.
