All degradable organic materials are decomposed by microorganisms, and considerable amounts of nitrogen end up as gaseous metabolites. No matter what procedure is chosen for getting rid of organic wastes (wastewater treatment, landfiling, and composting), microbial communities will always be involved in the decomposition process, and hence, emissions of greenhouse gases, including nitrous oxide ( N2 O ) , are inevitable with these processes. N2 O is an influential greenhouse gas, vital on climate change, and also is a depleting substance of stratospheric ozone. Any instantaneous or eventual N2 O emissions during wastewater treatment, biosolids landfilling, and composting must be measured as anthropogenic intrusion of global N2 O cycle, and thus plays a decisive role in ozone depletion. This paper reviews the current available literatures concerning N2 O emissions from wastewater treatment facilities, biosolids landfilling, and composting. The outcome of this survey portrays that each process can release a...read more

TL;DR: Analysis of literature data enabled the identification of the most important operational parameters leading to N(2)O emission in WWTPs: (i) low dissolved oxygen concentration in the nitrification and denitrification stages, (ii) increased nitrite concentrations in both nitrified stages, and (iii) low COD/N ratio in theDenitrification stage.
