Current Uses (II)

Company - Energy-Inc Pyrolysis (decompose organics w/o O2)Gasification (produce syngas w/o combustion)Heat/energySyngas: 1,885,000 MMbtu/yearBiochar: 9,125 tons of biochar annuallyElectricity: 22,000 kWh

Energy-Inc Number500 tons of waste per day22,000 KWh of electricity or thee quivalent of 22,000 homes per hour1,100,000MM btu of thermal energy per yearor1,885,000 MMbtu of syn gas per year and9,125 tons of biochar annually

Switch from disposal to utilizationSterilize and recycle wasteOptimize the process to reutilize as much waste as possibleCreate a cost effective processSave money, preserve landfill space, follow regulations Our Goals

Inputs: (~10 tons/day)Gauze (99% collagen)Plastic (syringes)Gloves (latex)NeedlesOutputs: SteamCO2Possibly the syngas itselfOrganic fertilizerOverall Inputs/Outputs

ljworld.comSeparate waste in specified containers (completed by medical facilities) Pick up waste and deliver to reutilization facilitySend to reactor to turn into syngasSend to Thermal Residence Chamber, which keeps the gasification going and brings to equilibriumGo through a heat recovery steam generatorClean gas with APC equipment and send to be sold or combustedGeneral Steps

cvcenvironmental.comProper disposal of medical waste has been regulated since 1988

Hospitals demand more cost effective waste treatment techniquesEmphasis on reusing the treated waste

Medical waste can be turned into useful, profitable products such as steam, syngas, and fertilizers
