The suitable dustbin can cause a significant increase in household participation in separated dry waste at production source and recycling rate. This study was conducted on 100 households in Tehran for two weeks for households' wastes without any intervention. After two weeks, the tough-flexible bag dustbins were delivered to the families. At the next stage, by analysing the separated dry wastes by households, comparing the cost of new bag dustbin with plastic garbage bags, and completing some questionnaires, it was concluded that about 92% of households believed that waste bag dustbin was much more accessible and hygienic. The use of plastic garbage bags was decreased an average by 2, after using new bag dustbins. Moreover, the use of bag dustbins has more cost-effectiveness rather than plastic bags (about 54%). Before and after the intervention, the source separation and recovery rate was 0.19 and 0.18, respectively. The amount of wet waste in the waste bag dustbin was decreased to 62.26% after the intervention. The decrease of wet waste in the separated dry waste enhanced the quality of recycled materials.
合适的垃圾桶能够显著提高家庭在源头对干垃圾进行分类的参与度以及回收率。本研究在德黑兰的100户家庭中进行，为期两周，期间对家庭垃圾未进行任何干预。两周后，向这些家庭发放了软硬适中的垃圾袋式垃圾桶。在下一阶段，通过分析家庭分类的干垃圾、比较新的垃圾袋式垃圾桶与塑料垃圾袋的成本，并完成一些问卷调查，得出的结论是，约92%的家庭认为垃圾袋式垃圾桶更方便且更卫生。使用新的垃圾袋式垃圾桶后，塑料垃圾袋的使用量平均减少了2个。此外，使用垃圾袋式垃圾桶比使用塑料袋更具成本效益（约54%）。干预前后，源头分类和回收率分别为0.19和0.18。干预后，垃圾袋式垃圾桶中的湿垃圾量降至62.26%。分离出的干垃圾中湿垃圾的减少提高了回收材料的质量。
