Abstract The operation of an anaerobic digestion located on a farm and primarily fed by cattle slurry, manure and ensiled maize, has been simulated using the Anaerobic Digestion Model 1, combined with a thermodynamic model. The effect of temperature on the biological reactions has been taken into account, as well as the limited availability of the substrates. This can be compensated by co-digesting other substrates easily found in the vicinity of the farm such as glycerol (waste from biodiesel production). Strategies based on glycerol feeding or temperature set points change have been investigated in order to control the methane production.
