Abstract :

Biological treatment is known as most effective method of organic matter elimination in municipal solid wastes. These include aerobic ad anaerobic compost. Presently anaerobic method is well known as a suitable technique for energy production. The methane production by anaerobic method is useful for energy production as well as direct fuel and also mechanical functions. Thus، present investigation is carried out in the light f greenhouse gas reduction، environmental protection and reduction of municipal waste management costs. In this research methane production from municipal waste was carried out at laboratory scale. Initially we used wastewater from dairy factory that contains high BOD. The methane production was examined at medium (about 35) and high (about 65) temperatures. All relevant parameters such as humidity، pH، load factor and efficiency were measured. The results show that methane production is more evident at lower temperatures. About 0.21 to 0.65m3 of methane can be produced from each kilogram of waste.
