本研究涉及清道夫和他们的作用，在回收废物在南部拉合尔。数据来自325个不同的拾荒者、旧货店和中间人。Allama Iqbal镇的废物产生率为每人每天0.80公斤。在巴基斯坦的研究地区和其他城市，没有正式的废物分类，这项活动主要由非正规部门负责，拾荒者是其中的主要利益攸关方。科瑞瓦拉斯Pheriwalas、拾荒者、街头拾荒者和垃圾场拾荒者是不同类型的拾荒者。拾荒者具有不同的社会经济和社会人口特征。所有年龄段的男女、贫困难民、移民和少数民族都参与回收废物。Pheriwalas从家庭和商店购买可回收物品，所有其他拾荒者直接从废物中回收可回收物品。所有的拾荒者都把可回收的垃圾卖给旧货店的经销商或承包商，然后再卖给中间商或回收行业。大多数可回收材料包括各种纸张，纸板，金属废料，塑料，宠物瓶，干面包，鞋，骨头等物品的价格取决于其质量或拾荒者和承包商之间的协议。拾荒者的收入取决于从废物中回收或从家庭购买的可回收物品的数量以及可回收物品的质量。据估计，在该地区工作的所有拾荒者每月回收的可回收材料总量约为525吨，每月创收30 875美元。他们贫穷，受到官员的骚扰，在工作期间面临健康和安全问题。尽管拾荒者的经济和社会地位较低，但他们对环境和经济作出了重要贡献。拾荒者不仅减少了废物，还为回收行业提供了二次材料，节省了SWMD在清扫、运输和处理废物方面的支出。拾荒者活动的总体影响在经济和环境方面都是积极的。在各类拾荒者中，Korreywalas经营的家庭垃圾收集系统是最好的。如果政府或有组织的私营部门帮助他们组织起来，为他们提供医疗和保健设施、个人保护设备和财政奖励，这一点可以进一步改善。(C)2011 Elsevier B.V.保留所有权利。
This study deals with the scavengers and their role in the recycling of waste in Southern Lahore. Data was gathered from 325 different scavengers, junkshops and middlemen. Waste generation rate in Allama Iqbal town is 0.80 kg per capita per day. In researched area and other cities of Pakistan there is no formal sorting of waste and this activity is mainly in the hands of informal sector of which scavengers are major stakeholders. Korreywalas. Pheriwalas, waste pickers, street pickers and dumpsite pickers are different types of scavengers. Scavengers have different socio-economic and socio-demographic characteristics. Males and females of all ages, poor refugees, migrants and minorities are involved in the recovery of waste recyclables. Pheriwalas purchase recyclable items form the household and shops and all other scavengers recover the recyclable items directly from waste. All scavengers sell recyclables to junkshop dealers or contractors, which resell these to middlemen or recycling industries. Most of the recyclable materials consists of variety of paper, cardboard, metal scrap, plastics, pet bottles, dry breads, heals of shoes, bones, etc. The price of an item depends on its quality or agreement among scavengers and contractors. The earnings of scavengers depend on the recovered amounts of recyclables from the waste or purchasing from the households and the quality of recyclable items. The estimated total amount of recyclable material recovered by all the scavengers working in the area is about 525 tons per month, which generate an income of US$ 30,875 per month. They are poor, suffer harassment from officials and face health and safety problems during the work. Despite of their low economic and social status, scavengers are making important environmental and economic contributions. Scavengers not only reduce the waste but also supply secondary materials to recycling industry, save the expenditures of SWMD in sweeping, transportation and disposing of waste. The overall impact of activities of scavengers is positive economically and environmentally. Of the various categories of scavengers household waste collection system run by Korreywalas is the best. This can be improved further if government or organized private sector helps them by organizing them, providing them medical and health facilities, PPEs and financial incentives.
