Question

!$%&/())=??/(/&&&

1,000 tons of mixed organic wastes need to be disposed of. The organic wastes have an average formula C45H78O20N. 1) To minimize the volume of produced greenhouse gases during disposal, do we select landfill or incineration for disposal of the waste? Why? (Other factors such as disposal costs are not considered during the selection. Methane, if produced, is not used as energy). 2) To minimize the greenhouse effect of the produced greenhouse gases during disposal, does the city choose landfill or incineration? Why? (Other factors such as disposal costs are not considered during the selection. Methane, if produced, is not used as energy; Assume the global warming potential of methane is 25 times as that of carbon dioxide).

Explanation / Answer

To minimise the volume of produced greenhouse gas the organic waste, we should opt Incineration as disposal method because these are organic waste are burned here, but in landfill huge amount of methane and carbondioxide is produced that contributute to greenhouse gas. hence incineration will be appropriate than landfills.

methane produced wont be used as the waste are burned in presence of oxygen which will completely decompose Carbon to co2. if then also methane produced it wont be enough to use as source of energy.
