对印度首都德里的城市固体废物（MSW）回收进行了调查和分析。研究发现，由废物回收商和可回收经销商组成的非正规部门在固体废物管理中发挥着重要作用。相关活动将近 17% 的废物运输至回收单位 (RU)。在此过程中，为回收贸易创建了一个完整的市场。目前的工作涵盖了对这种废物贸易的广泛研究，重点是废物链中最重要的单位，即回收商。对来自各个贫民窟的回收者的广泛采访和调查有助于评估德里回收贸易的市场机制并揭示这一非正规部门的细节。通过对回收商、可回收物经销商和市政当局进行多次实地采访，确定并描绘了从回收商到回收产品最终销售商的完整层次结构，并确定了每个层次的利润。废物贸易各个层面的每种产品的附加值也被确定。随后提出了两个模型来评估无组织废物贸易正规化的可能性。结论是，组织该部门是可能的，但这将使超过 66,000 名回收者失业，因为组织一项目前为社会最贫困阶层的近 89,600 名回收者提供就业和日常生活的活动的结果。这项工作还探讨了回收者生活的各个方面，并提供了城市固体废弃物的经济学细节。 (c) 2004 Elsevier B.V. 保留所有权利。
Recycling of the municipal solid waste (MSW) was investigated and analyzed in the Indian capital city of Delhi. It was found that an informal sector comprising waste recyclists and a hierarchy of recyclable dealers plays an important role in the management of solid waste. The associated activity transports nearly 17% of the waste to the recycling units (RU). In this process an entire market is created for the recycle trade. The present work covered an extensive study of this waste trade with emphasis on the most important unit of the waste chain, the recyclists. Extensive interviews and surveys with recyclists from various slums helped in evaluating the market mechanisms of the recycla trade in Delhi and in revealing details of this informal sector. Through a number of field interviews undertaken on recyclists, recyclables dealers and municipal authorities, a complete hierarchy from recyclists to the final sellers of the recycled product was identified and delineated and the profits at each level determined. The value addition to each product at every level of the waste trade was also determined. Two models were subsequently proposed to evaluate the possibility of formalizing the unorganized waste trade. It was concluded that it is possible to organize the sector, but this would leave more than 66,000 recyclists without employment, a consequence of organizing an activity that presently provides employment and daily living to nearly 89,600 recyclists who belong to the poorest strata of the society. The work also probes into the various aspects of the lives of the recyclists and provides details of the economics of MSW. (c) 2004 Elsevier B.V. All rights reserved.
