Greenhouse Gases Emissions from Wastewater Treatment Plants: Minimization, Treatment, and Prevention

Table 1

Values assigned to the parameters used to estimate CO₂ emissions.

Parameter	Units	Reference
CO2 emissions from energy consumption	0.391 kg CO2/kW⋅h	[40]
CO2 emissions from COD oxidation	0.08 kg CO2/kg COD
CO2 emissions from CH4 combustion	3.5 kg CO2/Nm^3

Estimated taking into account an elemental composition of C_2.43H_3.96O for the biodegradable fractions of the COD [41]. Calculated from stoichiometry and ideal gas law.
