Evaluation of Methane and Carbon Dioxide Emission Decrease Through Waste Composting
<p>The organic waste disposal under anaerobic conditions emits Methane, which causes increased global warming. This study attempts to find the emission factor in windrow waste composting systems from two sizes of gathered organic waste piles. Designed to compare two groups of composting piles,...

<p>The organic waste disposal under anaerobic conditions emits Methane, which causes increased global warming. This study attempts to find the emission factor in windrow waste composting systems from two sizes of gathered organic waste piles. Designed to compare two groups of composting piles, one pile consisted of 500 kilograms of waste originating from local authorities while the other amounted to 250 kilograms of waste collected from households. With six piles of each type, aeration was done by manual turning and emissions were sampled in closed flux chambers and analyzed by gas chromatographs. A control experiment, modeling landfill sites, was set up in a one x one x one meter hole. Results from the experiment showed that emission ratios from the 500 kg was 1.3613 x 10<sup>-3</sup> g CO<sub>2</sub>-eq kg<sup>-1</sup> wet waste, and 1.3427 x 10<sup>-3</sup> g CO<sub>2</sub>-eq kg<sup>-1</sup> wet waste from the 250 kg experiment.
