Selection of City Multi-source Organic Solid Waste Disposal Methods Based on Life-cycle Carbon Emission and Economic Cost Analysis
Quantitative decision-making methods based on carbon emissions and economic analysis have played an important role in the selection and decision of solid waste treatment and disposal technology.A medium-sized city in Yangtze River Delta was taken as an example,the selection method of multi-source organic solid waste(municipal sludge,food residue,kitchen waste)collaborative treatment and disposal was explored.Different organic solid waste treatment and disposal process combinations were established based on life-cycle theory,and the carbon emission and economic cost were analyzed.On this basis,the feasible solution of low carbon emission and low economic cost was obtained by using linear goal programming method.The results showed that under the lowest carbon emission scenario,it was recommended that all kinds of organic solid waste should be treated with anaerobic digestion,but different disposal methods should be selected for biogas residue.Under the lowest economic cost scenario,compost or incineration was a better option,but if you rely on existing facilities for co-composting or incineration,the amount of co-consumption should be considered.
