"""
Equation 4.1 (tier 1)
Calculates the CH4 emissions from biological treatment for MSW.
Contrary to equations 4.1 in guidelines, no summation over treatment types.
Argument
--------
m (Gg/year) : float
Amount of organic waste that is treated.
(wet weight)
ef_ch4_biotr (g/kg) : float
CH4 emissions factor
r (Gg/year) : float
total amount of CH4 that is recovered
Returns
-------
VALUE: float
