摘要

A solid waste recycling approach is a part of the sustainable and effective waste management system for most of the cities in the world. Although the recycling part of waste management has been ignored by the local authorities, many individual waste collectors and dealers have been performing recycling activity as a source of income for a long time in Bangladesh. In this paper, a traditional recycling practice of solid waste was investigated and analyzed in the Khulna city of Bangladesh. A complete hierarchy from waste collectors to recycling industries in the private sector was identified. The study revealed that 7.2 % (37.23 tons/day) of the total generated waste or 53.2 % of the recyclable solid waste (RSW) was recycled daily in Khulna. The private sector was found to deal only with RSW. RSW collected by the private sector included paper, glass, plastic, aluminum, iron, tin, bones and tyres. Except for bones, paper, iron, plastic and tyres all other retrieved materials were transported to industries located in Dhaka, the capital city of Bangladesh as raw materials for new products. Three models are proposed to evaluate the possibility of organizing the unorganized waste recycling practice. The third model seems to be feasible both economically and socially.
