  • Methods and apparatus for encapsulating hazardous debris
    Patent number: 7074174
    Abstract: A method of collecting, treating, transporting and disposing of hazardous debris which combines the standards of macroencapsulation and microencapsulation and involves the use of a liner to contain hazardous debris together with reagents that reduce leachability of a constituent of the hazardous debris. The liner is supported in a rolloff box or other transportable container on site where the hazardous debris is collected. Prior to placing hazardous debris into the liner, a layer of reagent(s) is provided in the bottom of the liner. Once hazardous debris is loaded in the liner, addition free flowing reagent(s) is/are added to fill void space in and around the hazardous debris, after which the top of the liner is sealed for disposal in a landfill.
