Abstract Results of extended research on laboratory scale have shown that relatively high gas productions can occur at digestion of animal manure in fed-batch (=Storage)- systems at ambient temperatures. High gas productions are also reported at on-farm storage of animal manure. In order to predict the gas production during the storage of animal manure at different conditions, a model is developed based on first order kinetics for the hydrolysis and on Monod kinetics for methanogenesis. Results of anaerobic digestion of manure in both CSTR- and fed-batch systems have been used for the estimation of constants. The model predicts that, when continuously 15% of the storage is filled, no gas production is produced, at a temperature of 15°C and a storage capacity ≤ 100 days and at a temperature of 10°C and a storage capacity ≤ 150 days. At higher temperatures and longer storage capacities methane gas is always produced.
