For evaluating the environment impact of domestic existing disposal modes of rural living waste and offering the decision-making basis for the improvement and development of them,this study compares two typical domestic centralized waste treatment modes in the rural areas in the eastern part of the Shandong- unified collecting,transporting and landfill(Mode 1),and a combining mode of classification in situ and centralized treatment(Mode 2)to assess.The life cycle of the waste is divided into parts of collection,transportation,compression and final disposal and treatment,whose life cycle assessment of environmental emission is carried on in the study.Results show that through classification in situ compost processing,environmental impact load of Mode 2 can be 36.55%lower than Mode 1,and the greatest effect exists in the final disposal and treatment unit,but the waste transportation accounts for a small proportion of the overall environmental pollution.The advice for Mode 1 is to recycle the landfill methane and carbon dioxide emissions,to reduce global warming potential is the key to ease the environmental load,and the advice for Mode 2 is to collect the composting leachate and control the orders emissions,to decrease the impact of eutrophication and the affect of people's health nearby.
