In Karachi, about 20% of the waste is picked up by the waste scavengers (Pickers) as the salable items (Khan & Athtar, 2000). There are scavengers’ colonies in Karachi, where waste-transporters are attracted for delivering delivering the waste to them instead of taking it to the official wastewastedump sites (Fig.5).

Almost 20% waste is left out in the dustbins on the mercy of the Mother   Nature to take care of (Fig.6) or most often burned openly to ashes. About 60% of the garbage produced in the Karachi metropolitan area from official and/or unofficial dustbins of the city is transported transported to the uphill areas located 30-35 km away from the city and disposed in open air. In the background, huge piles of solid dumps can be seen (Fig.7). Figure 6: Waste pickers scatter solid waste after collection of saleable waste. At the dumping sites, more than 400 tonnes of organic waste is used burnt to extract metals, where smock and dust are generated to the crisis level of the health environment (Fig.8).
