GENERATION AND ASSESSING THE COMPOSITION OF HOUSEHOLD SOLID WASTE IN COMMERCIAL CAPITAL CITY OF BANGLADESH

Generation of solid waste (SW) is a major problem in ur ban areas and its management is obligatory functions for both urban local authority and the urban people. Present paper presents a study of household solid waste generation (HSWG) rate, composition, characterization, potentials of its recyclable components and households’ attitudes towards waste management in commercial capital city of Bangladesh named as Chittagong City (hereafter called Chittagong City). This stud y was conducted at Midtown Housing Society, Rahamatgong and Sarif colony of Jamalkhan Ward under Chittagong City Corporation (CCC). The study involved a structured questionnaire and encompassed 55 households from five different socioeconomic groups (SGs): low (LSG), lower middle (LMSG), middle (MSG), upper middle (UMSG) and high (HSG). It was found that the residential waste generation rate was 0.28 Kg/per son/day and an average household generation of 1.48 kg of waste per day. The household solid waste (HSW) comprised of nine categories of wastes with vegetable/ food waste being the largest component (72%). Vegetable/ food waste generation increased from 53% (observed for HSG) to 89% (for LSG). By weight, 77% of the waste was compostable in nature. The generation of residential solid waste (RSW) was found positively correlated with family size (r xy = 0.8483) at 1% significant level. For systematic collection and disposal o f the municipal solid waste (MSW), it is essential to develop ward-based participatory solid waste management programs. Finally, the research suggests some appropriate recommendations on how a participatory-sustainable residential solid waste management system could be developed in the area of CCC to achieve its goals.
