A system with property-close source-separation of thirteen different solid household waste fractions in a residential area in southern Sweden, including the implementation of new systems for source-separation of food waste, waste electric and electronic equipment, hazardous waste and fat, oils and grease was monitored over a 2-year period. Continuous weighing of disposed waste and repeated waste composting analyses were used to investigate recycling behaviour of households in the area and to monitor the composition of disposed waste. Results show that 34% of the total amount of generated waste was currently diverted to material recycling. The removal of recyclables from residual waste could be significantly increased, as more than 80% of all waste in the area (bulky waste excluded) was either covered by the Producer Responsibility Ordinances on packaging and newspaper or constitutes food waste suitable for biogas production. Food waste still represented almost 30% of all residual waste in the study area and was thus the fraction with the greatest potential (on weight basis) for increased source-separation.
在瑞典南部的一个居民区中，有一个系统可以将 13 种不同的固体生活垃圾进行近乎同源的分离，其中包括实施新的食物垃圾、废弃电气和电子设备、危险废物以及脂肪、油和油脂的同源分离系统。该系统在两年的时间里进行了监测。通过对处理废物的连续称重和对重复进行的废物堆肥分析，研究了该地区家庭的回收行为，并监测了处理废物的成分。结果表明，目前 34%的总废物量已被转移到材料回收利用中。如果能够显著提高从残余废物中去除可回收物的能力，那么该地区超过 80%的废物（不包括大件垃圾）就可以通过包装和报纸生产者责任法规或适合沼气生产的食物垃圾进行覆盖。在研究区域中，食物垃圾仍然占所有残余废物的近 30%，因此是具有最大同源分离潜力（按重量计）的垃圾。
