2010年上海世博会垃圾组分的预测

Site Investigation on MSW in Shanghai Commercial Center and Its Use for the Prediction of Wastes Generation in Shanghai EXPO 2010

为了便于2010年上海世博会期间生活垃圾的处理与处置，选择了和世博园区垃圾性质相近似的南京路步行街为参照区，进行垃圾组分的调研，预测模拟世博园区垃圾的组成与性质。研究结果表明：南京路步行街垃圾中食物垃圾占50％左右，塑料和纸张占45％左右，而一般的城市生活垃圾中塑料和纸张只占20％～30％左右，可见对于类似的垃圾资源化程度非常高。因此对于世博园垃圾进行分选，实现各组分垃圾的分流，可以更好地实现垃圾的资源化、减量化。

In order to have a proper MSW management of Shanghai EXPO 2010 which will be held in 2010, an investigation on MSW collected from Nanjing Road, the commercial and business center of the city, was conducted.It was found that the percentages of food waste and waste plastics and paper from the Road are 50% and 45%, respectively, comparing with 20% to 30% of waste plastics and paper in the MSW of Shanghai averagely. Hence, it seems that the solid wastes in the Nanjing Road should have a higher value than the general wastes, indicating that the MSW in the future EXPO 2010 should be sorted and recycled.
