Mesophilic anaerobic co-digestion of cow manure and biogas crops in full scale German biogas plants: A model for calculating the effect of hydraulic retention time and VS crop proportion in the mixture on methane yield from digester and from digestate sto

► New comprehensive model for co-digestion of biogas crops and cow manure. ► Coupling of HRT with VS-proportion of biogas crops in the mixture. ► Calculatin of methane yield from digester and storage tank. ► Methane yield in storage tank as function of temperature and storage time.
