Abstract
During a two years period the energy consumption of four different cheese factories has been analysed. The whey of the four cheese factories is used for fattening pigs in an attached piggery. All four factories are equipped with biogas-digesters which use the slurry from the piggeries for methane production. The overall energy consumption per ton of milk transformed varies from 600 and 885 MJ. This includes the energy used for heating the fermentation rooms and the cheese maker's flat as well as the energy used for the piggery. 10 to 40% of the total energy is being consumed in form of electricity. Three of the four digesters are working at temperatures of 30 to 35/sup 0/C. One is run in the psychrophilic range, i.e. without heating system. The heated systems use 20 to 40% of the total gas production for heating the digesters. The net gas production of all four systems is of the same order of magnitude. The necessary energy for milk transformation depends on the type of installation used and on the skill of the cheese maker to use his installation economically. Between 30 and 60% of the total energy demand of the four factories has been covered
