Where:
MNMOC = Total NMOC emission rate from the landfill, Mg/yr.
k = Methane generation rate constant, year-1.
Lo = Methane generation potential, m3/Mg solid waste.
Mi = Mass of solid waste in the ith section, Mg.
ti = Age of the ith section, years.
CNMOC = Concentration of NMOC, ppmv as hexane.
3.6 * 10-9 = Conversion factor.
Where:
MNMOC = Mass emission rate of NMOC, Mg/yr.
