η pc represents the power factor effectiveness once it is equal to 1; β represents the
energy cofactor (0.004–0.006/°C); η r represents the mode of energy production; and
T cref is the cell temperature in °C which can be obtained from the following equation:

(b) the production rate of biogas and the bioenergy considering bioreactor methane content of the
biowaste
