Abstract: Composting organic waste is a key to ensure an environmental sustainability in Fiji that will benefit key stakeholders: households and local government. Since December 2012, the Home Composting Project operated by Suva City Council (SCC) has been organizing households to dispose organic compostable waste into compost bins provided by the council and thereby reducing both damage caused by landfill disposal, and emissions of carbon dioxide and methane. To date, about 400 households in Suva have been voluntarily participating in the project with the SCC to assist in the reduction of greenhouse gases (GHG). This study investigates how much this Home Composting Project is currently reducing CO2 and CH4 in Suva and analyses other related potential benefits. Primary data was obtained using the Customer After-Care Survey conducted by the survey team made up from three sectors: SCC, Japan International Cooperation Agency (JICA) and the University of the South Pacific. The study revealed: (ⅰ) the quantity of organic waste produced by each household and the quantity of organic fertilizer this would create, how much CO2 and CH4 this amount of waste would produce if disposed of in landfill or in an incineration, how much carbon dioxide, methane and disposal costs can be reduced if all or half households in Suva City utilized a compost bin; (ⅱ) how much CO2 emission by garbage collection trucks can be reduced by the reduction of the organic waste using compost bins since the amount of garbage for collection would decrease; and (ⅲ) how much recyclable waste the household sector is putting into rubbish bins as in plastic PET bottles, aluminium cans, and papers. The research includes discussion related to the challenges and the economic benefits for the local government (SCC). Further to the above research, the paper evaluates other opportunities to reduce food waste, carbon dioxide and waste disposal costs. The first is to reduce the frequency of pick-ups from three to two days weekly, and the second is to start a recyclable waste collection service. Three types of recyclable waste are considered: plastic PET bottles, aluminium soft-drink cans, and paper accumulated by households. viii Finally, the study aims to assist the local government’s decision-making on the best possible waste disposal service for the city council as this matter has long weighed heavily on government finances in Fiji. Moreover, it is the hope of the author that this research will also encourage other cities and countries in the South Pacific to consider changing their methods of waste management for the environmental sustainability of this region.
