Generation and Assessing the Composition of Commercial Solid Waste in Commercial City of Bangladesh (original) (raw)

The study was conducted in Jamalkhan Ward, Chittagong, Bangladesh to determine the generation rates, physical composition and characterization of commercial solid waste (CSW) and to identify the current situation of commercial solid waste management. A structured questionnaire was processed and waste collected from different waste generating sources were segregated and weighed. Commercial solid waste generation rate was found 0.44kg/person/day and an average commercial unit generated 3.61 kg of waste per day. In the generation of CSW, vegetable/food waste was highest (35%) followed by 14% of packaging material and 13% of plastic/polythene/rubber and lowest (2%) found as can/metal/tin. By weight, 57% of the waste was compostable in nature. The generation of CSW was found positively correlated with staff size (rxy = 0.8245) at 1% significant level, which means commercial unit with more staff generate larger quantity of solid waste per day. It was also found a positive correlation between the establishment cost (rxy= 0.9945) and the generation of solid waste at 1% significant level which reveals commercial unit that required large establishment cost have the tendency to generate larger quantity of solid waste each day. Municipal authorities are usually the responsible agencies for solid waste collection and disposal, but the magnitude of the problem is well beyond the ability of any municipal government to tackle. It is necessary to take initiatives by both public and private sectors for effective management of waste. For systematic collection and disposal of the commercial waste, it is essential to develop ward-based participatory solid waste management programs.
