| Abstract/Contents: | "Emissions of carbon monoxide (CO) were observed from decomposing organic wastes and litter under laboratory, pilot composting plant, and natural conditions. Field studies included air from inside a compost heap of about 200 m3, emissions from composting of livestock wastes at a biologically operating farm, and leaf litter pile air samples. The concentration of CO was up to 120 µmol mol-1 in the compost piles of green waste, and up to 10 µmol mol-1 in flux chambers above livestock waste windrow composts. The mean CO flux rates were approximately 20 mg CO m-2 h-1 for compost heaps of green waste, and varied from 30 to 100 mg CO m-2 h-1 for fresh dung windrows. Laboratory studies using a temperature and ventilation-controlled substrate container were performed to elucidate the origin of CO, and included hay samples of fixed moisture content at temperatures between 5 and 65°C, including nonsterilized as well as sterilized samples. The concentration of CO was up to 160 µmol mol-1 in these experiments, and Arrhenius-type plot analyses resulted in activation energies of 65 kJ mol-1 for thermochemically produced CO from the nonsterilized compost substrate. Sterilized samples showed dramatically reduced CO2 but virtually unchanged CO emissions, albeit at a slightly lower activation energy, likely a result of the high-temperature sterilization. Though globally and regionally these CO emissions are only a minor source, thermochemically produced CO emissions might affect local air quality in and near composting facilities." |
