在瑞典南部的六个城市，类似的社会经济条件，但不同的收集系统的城市固体废物（MSW）的组成和数量进行了分析。在1998-2004年期间进行的26次分析中，对残留废物的样本进行了分类和称重，分为21类。收集并比较了同一地区总废物流量的收集数据，包括来源分类的回收材料。多变量数据分析已被应用。基于重量的计费减少了50%的剩余家庭垃圾的交付量，但不知道在多大程度上不适当的材料路径已经发展。随着路边收集更多的金属，塑料和纸包装被分离，并留下回收。当在路边系统中单独收集生物降解物时，干可回收物的整体分类增加。由于废物成分分析存在很大的不确定性，因此很难就对特定可回收物的影响或残余废物成分的变化得出有力的结论。(c)2006爱思唯尔有限公司保留所有权利。
Composition and quantity per person of municipal solid waste (MSW) have been analyzed in six municipalities in southern Sweden with similar socio-economic conditions but with different collection systems. Samples of residual waste have been sorted, classified and weighed in 21 categories during 26 analyses that took place from 1998-2004. Collection data of the total waste flow, including source sorted recycling materials, in the same area have been compiled and compared. Multivariate data analyses have been applied. Weight-based billing reduced delivered amounts of residual household waste by 50%, but it is unknown to what extent improper material paths had developed. With curbside collection more metal, plastic and paper packaging was separated and left to recycling. When separate collection of biodegradables was included in the curbside system, the overall sorting of dry recyclables increased. The large uncertainty associated with waste composition analyses makes it difficult to draw strong conclusions regarding the effects on specific recyclables or the changes in the composition of the residual waste.
