| dc.description | The composition of waste disposed of is crucial for planning and decision-making of a sustainable waste management system. The municipal solid waste (MSW) from three principal council areas in Kuching, which are Kuching South City Council (KSCC), Kuching North City Hall (KNCH), and Padawan Municipal Council (PMC) are collected and characterised. This waste composition is evaluated for the sample collected directly from the source and lab analysis is conducted on the sample collected from the landfill. The municipal solid waste samples are collected directly from the pre-categorised source location according to the socio-economic level. The municipal solid waste generated in Kuching city has been analysed by using both qualitative and quantitative analysis, as well as characterising the municipal solid waste samples based on their physical, chemical, and thermal characteristics. This study discovered that there is no significant difference in the waste composition trend generated in different residential areas. Organic waste is found to be the highest waste component in all socio-economic groups. For the residential areas, the top three waste compositions are organic wastes (61.58% w/w), plastics (12.06% w/w), and nappies/sanitary napkins (11.67% w/w). The sample collected from the landfill is divided into two groups, the sample from the new landfill where the solid waste was disposed of in recent two years and the old landfill where the solid waste was disposed of more than 5 years. The moisture content, volatile matter, ash, and fixed carbon content were 54.71%, 26.42%, 18.67% and 0.21% respectively for the old landfill and 63.26%, 22.83%, 13.73% and 0.18% for the new landfill sample. The calorific value for the old landfill sample is found 2041.86 kcal/kg and the calorific value for the new landfill sample is found 2891.9 kcal/kg. Thus, the thorough evaluation in this study reveals that landfill waste is not suitable for waste to energy incineration process. The amount of solid waste iv generated in Kuching city is increasing in trend as the population in Kuching city is increased. A sustainable waste management system with a zero-waste approach is proposed in Kuching city. | |
