Micro-encapsulation

Micro-encapsulation is performed on debris such that the "leachability of the hazardous contaminates is reduced". Micro-encapsulation is similar to the stabilization process, but is typically limited to inorganic (heavy metal) contamination on debris of simple geometric shapes. During micro-encapsulation, contaminants on the surface are chemically treated to reduce toxicity utilizing reagents such as lime kiln dust, Portland cement, fly ash, or similar materials. Following micro-encapsulation, the waste is placed in a secure landfill.
