This article presents the informal recycling sector's (IRS) social, economic driving factors in five cities in Indonesia and their contribution to waste management in the cities. An on-field analysis was conducted by random and incidental sampling method of questionnaire administration followed by observation. Among the respondents ( = 178), 79% of individuals were waste pickers, 15% were small-scale waste collectors, and 6% were medium-scale waste collectors. The majority of the waste pickers sampled are male (79%). The amount of waste collected by individual waste pickers is 43.87 kg person day, a corresponding recycling rate of approximately 12%, and an average monthly income of US$91.7. Gender differences are apparent as the male waste pickers generated higher incomes than those earned by their female counterparts (US$128.3 for men and US$69.7 for women) even as their average work hours are similar to that of the men (7.8 and 7.6 hours day, respectively). Economic motives are the respondents' primary driving factors as moving to large cities accompanied by their family members. The study concluded that the IRS plays substantial contribution to waste management; further integrating them into the waste management system via IRS association, additional investment, formulation of law and policies and efforts by municipalities can give various benefits for involved stakeholders, the community and the environment. The results can serve as a significant reference for improving the solid waste recycling system and informal sector management in Indonesian cities and other developing countries.
本文介绍了印度尼西亚五个城市非正式回收部门(IRS)的社会、经济驱动因素,以及它们对城市废物管理的贡献。通过随机和偶然抽样问卷调查和观察进行了实地分析。在受访者(=178)中,79%是拾荒者,15%是小规模废品收集者,6%是中等规模废品收集者。抽样的拾荒者大多数是男性(79%)。个体拾荒者收集的废物量为 43.87 公斤/人/天,相应的回收率约为 12%,平均月收入为 91.7 美元。性别差异明显,男性拾荒者的收入高于女性拾荒者(男性为 128.3 美元,女性为 69.7 美元),尽管他们的平均工作时间与男性相似(分别为 7.8 和 7.6 小时/天)。经济动机是受访者的主要驱动因素,他们为了与家人一起搬到大城市。研究得出结论,IRS 对废物管理做出了实质性的贡献;通过 IRS 协会、额外投资、制定法律和政策以及市政当局的努力,将它们进一步纳入废物管理系统,可以为相关利益相关者、社区和环境带来各种好处。研究结果可为改善印度尼西亚城市和其他发展中国家的固体废物回收系统和非正式部门管理提供重要参考。
