  • In-Situ Reclaimable Anaerobic Composter
    Publication number: 20120264198
    Abstract: An in-situ dry anaerobic composter containing 40% to 75% by weight solids and located in a section of ground including a pit having side walls and a bottom, an essentially impervious liner located in the pit such that the liner abuts the pit side walls and bottom to form a lined pit, a compostable material located in the lined pit and a gas management system for extracting a gaseous anaerobic decomposition product from the compostable material as well as methods for operating the anaerobic composter.
    Type: Application
    Filed: February 17, 2012
    Publication date: October 18, 2012
    Applicant: WASTE MANAGEMENT, INC.
    Inventors: Gary R. Hater, Roger B. Green, Christopher J. Pierce, Kevin Mieczkowski, Gregory C. Cekander

  • Treatment of TNT-contaminated soil
    Patent number: 6066772
    Abstract: A process for converting hazard explosives that are contaminating soil into reduced derivatives and thereafter converting the reduced derivatives into humic compounds by admixing the explosives contaminated soil with a natural microorganism source and with an oxidizable carbon source and subjecting the mixture to anaerobic conditions to produce an anaerobic bioremediation product containing reduced concentrations of explosives contaminants and thereafter combining the anaerobic bioremediation product with a compostable material and subjecting the second mixture to aerobic conditions to give an aerobic bioremediation product that is essentially free of explosives contaminants and their reduced derivatives.
    Type: Grant
