在一些东南亚国家，出现了一种称为“废物银行”的废物回收新方法，旨在鼓励社区成员回收并发展可持续的废物管理。本研究以印度尼西亚玛琅市桑帕玛琅银行 (BSM) 为案例研究，调查了废物库。本研究的目的是确定可回收物的流向以及废物银行参与者应分离哪些可回收物以有效赚取收入。第二个目标是估算废物银行系统中可回收物的潜在收入。详细数据（例如按可回收材料类型划分的重量）是在 2013 年 1 月 2 日至 4 月 4 日期间收集的。有 5 个团体参与了 BSM，其中一个[由至少 20 个家庭组成的社区 (COM)] 贡献了提交给 BSM 的大部分可回收物 (72%)。就COM而言，70个类别中只有14个类别（包括废纸、透明聚对苯二甲酸乙二醇酯瓶和饮用水聚丙烯杯）产生了80%的利润，其他项目应从清单中删除，以免参与者不知所措。这项研究发现，家庭每年可以通过废物回收平均赚取 322,000 卢比（23.2 美元）。废物银行的管理者可以强调，这一数额足以为促进 BSM 的运动中的儿童提供学习用品。
In some Southeast Asian countries, there has been a new approach to waste recycling called “waste banks,” which aims to encourage community members to recycle and develop sustainable waste management. This study investigated the waste banks using Bank Sampah Malang (BSM) in Malang City, Indonesia, as a case study. The aim of this study was to determine the flow of recyclables and which recyclables should be separated by participants of waste banks to effectively earn revenue. The second aim was to estimate the potential revenue from recyclables in the waste bank system. Detailed data, such as weight by recyclable material type, were collected from January 2 to April 4, 2013. There were five groups that participated at BSM, one of which [communities (COM) consisting of a minimum of 20 households] contributed the majority of the recyclables that were submitted to the BSM (72%). In the case of COM, only 14 of the 70 categories, including waste paper, clear polyethylene terephthalate bottles, and polypropylene cups for drinking water, generated 80% of the profit and the other items should be eliminated from the list to avoid overwhelming the participants. This study found that households can earn an average of 322,000 Rp (23.2 USD) per year from waste reclamation. The managers of waste banks can emphasize that this amount is sufficient to by school supplies for children in campaigns promoting BSM.
