Abstract
In this study, the cost, energy consumption, CO2 emission and final waste disposal of the incineration system and the combined system of garbage biogasification and incineration were investigated. These parameters in the two waste treatment systems were examined from the stages of the collection, transportation, intermediate treatment, ash transportation, landfill and recycling by using of the LCA technique. The costs of the CO2 reduction and energy consumption were converted to the economic costs and the total costs of these two systems were calculated respectively. The total cost of the garbage methane fermentation system was found to be lower than the incineration system, which indicated the better applicability of the former system.
