本文以上海市临港新城为例,在垃圾分类情景下对不同类型的生活垃圾处理手段进行碳排放评估.结果表明,临港新城生活垃圾处理过程的碳排放随着垃圾产生量迅速增长而增加,但是随着垃圾分类的实施,湿垃圾处理方式从简单的好氧堆肥逐渐演变为更加绿色低碳的厌氧发电制肥,与现状单位碳排放量相比,远期单位碳排放量下降约 38.51%.现状单位碳排放量约为 410 kg CO2-eq,规划近期单位碳排放量约为 390 kg CO2-eq,规划远期单位碳排放量约为 363 kg CO2-eq,单位生活垃圾处理碳排放量不断下降.
Assessment and Prediction of Carbon Emissions from Domestic Waste Treatment under the Scenario of Garbage Classification—Taking Lingang New Town in Shanghai City as an Example
Taking Lingang New Town in Shanghai City as an example,this paper evaluates the carbon emissions of different types of domestic waste treatment methods under the scenario of garbage classification.The results indicate that the carbon emissions during the domestic waste treatment process in Lingang New Town increase rapidly with the amount of waste generated,however,with the implementation of garbage classification,the wet garbage treatment method has gradually evolved from simple aerobic composting to a more green and low-carbon anaerobic power generation fertilizer,compared to the current unit carbon emissions,the long-term unit carbon emissions will decrease by about 38.51%.The current unit carbon emissions are about 410 kg CO2-eq,the planned short-term unit carbon emissions are about 390 kg CO2-eq,the planned long-term unit carbon emissions are about 363 kg CO2-eq,and the carbon emissions per unit of domestic waste treatment are continuously decreasing.
