Kinetic models of cumulative gas production.
| Models | Equations | Parameter description |
| First order [77] | | M = cumulative methane produced (ml/gVS) | Cone [78] | M | = methane predicted (ml/gVS) | Haldane [79] | | (/d) = hydrolysis rate constant | Monod [78] | | C = VS ratio of a cosubstrate over the total substrate VS (%) | Weibull [80] | | = the half-saturation constant of cosubstrate (%) | Transference [81] | | = half inhibition constant of the cosubstrate (%) | Modified Gompertz [78] | | λ = phase delay time | Modified logistic [81] | | = maximum biogas production rate (ml/gVS.d) | Modified Richards [81] | | n = shape factor, k = rate constant (1/d), t = digestion time (d), e = 2.718 |
