Sustainable solid waste management through 3R strategy in Gazipur City

Abstract

Generation of a huge amount of solid waste and its mismanagement has become one of the major concerned social and environmental issues in both urban and rural areas. Although municipal authorities are concerned about the importance of solid waste collection, disposal and recycling, it is difficult to deal effectively with the growing amount of solid waste generated with the increase of population. This research determines the waste generation rate (per capita per day) to determine the composition of wastes in houses, secondary dumping site and final dumping site with the amount of the waste that can be reduced and the possible amount of economic benefits that can be achieved through adopting 3R policy. The results suggest that it will be economically benefitting if 3R policy in Gazipur City is adopted. Finally this study, based on the findings, give suggestions for a way leading to a sustainable waste management system for a city.
