METHOD FOR PRODUCTION OF ORGANIC AMMONIUM SULFATE USING CAPTURED NH3 AND NH4 PRODUCED BY AEROBIC COMPOSTING

摘要

An aerobic composting process for producing an organic ammonium sulfate product is provided, including providing an enclosed composting apparatus for decomposition of a source of nitrogen; mixing said source of nitrogen with a source of carbon, thereby creating a biomass having a high solids content; moving said biomass down the composting trench as the aerobic composting process progresses; providing aerobic bacteria to highly selectively convert the available nitrogen compounds from said biomass into NH3 and/or NH4 and CO2 without addition of external heat; capturing the NH3 and/or NH4 and CO2 from the atmosphere of the composting apparatus in an aqueous solution; adding a source of sulfate to said aqueous solution containing captured NH3 and/or NH4 and CO2; and processing said aqueous solution containing a source of sulfate and captured NH3 and/or NH4 and CO2 to obtain preferrably organic ammonium polycarbonate and/or solid or concentrated liquid ammonium sulfate product.
