The slaughterhouse wastes achieved methane yields of 261.35–594.59 mLCH4 gVS−1. Methane production kinetics varied, identifying the unsuitability of common models. Three parameter models were unable to model methane production of high fat wastes. The fixed point of inflection of three parameter models being the root cause. Variability in the point of inflection critical through a fourth shape parameter.
