Solid Waste Management System through 3R Strategy with Energy Analysis and Possibility of Electricity Generation in Dhaka City of Bangladesh

Abstract

Solid waste management is considered as one of the serious environmental problems in developing Asian countries like Bangladesh. Although municipal authorities in the city of Dhaka recognize the importance of adequate solid waste collection as well as resource recovery and recycling, it is beyond their resources to effectively deal with the growing volume of solid waste. As a result, solid waste is dumped indiscriminately on streets and open drains causing serious health risks and degradation of the living environment for millions of urban people. In the last decade, the importance of community involvement in solid waste management and the use of adaptive technologies to improve solid waste management systems have been recognized but waste is a material that no longer serves a purpose and is therefore discarded. All wastes are particularly hazardous if not disposed of carefully, they will have an impact on the environment, be it unsightly litter on urban streets or polluted air, soil, or water. Solid waste management practices are not very satisfactory in the recent world and adequate policies and awareness about various aspects of waste management are needed to help reduce waste generation and improve waste management processes. This research paper has worked on Dhaka city, the capital city of Bangladesh and it has tried to find out the current status of solid waste through 3R strategy including energy analysis. Moreover, this paper has discussed the potential of power generation from solid waste.
