Patent ID: 7939705

Claim:
A method for treating an asbestos containing material (ACM) with a mineralizing agent for the purpose of converting the asbestos into an essentially asbestos-free mineral that contains non-detectable concentrations of asbestos when analyzed using transmission electron microscopy, X-ray diffraction, and optical microscopy techniques, the method comprising: shredding the ACM into shredded ACM in a shredding apparatus to increase the the surface area and discharging the shredded ACM; wherein shredding the ACM comprises using a shredding system that shreds the ACM into shredding ACM and discharges the shredded ACM by propulsion through a screen containing openings approximately 2 inches in diameter, and applying the mineralizing agent to the shredded ACM using an apparatus to evenly spray the mineralizing agent over the shredded ACM after it is discharged and while the shredded ACM is falling through the air from the shredding apparatus.
