| Abstract | Solid Waste Management is one of the most significant problems for achieving sustainability in any places. The goal of this study was to assess the existing solid waste separation practices in AIT campus, by estimating the solid waste generation rate, physical characterization and composition of solid wastes in academic, residential, and commercial area in AIT. The waste generation rates were 0.9, 0.2 and 0.4 tons per day in residential, academic and commercial area in AIT, respectively. The estimated per capita solid waste generation rate was 0.5 kg/capita/day. It is expected, however, that the solid waste characteristics for the AIT campus would change over time. The institution generated 544 tons/year of solid waste, which was nearly 0.5 kg/day/person. Food wastes and plastic wastes had the highest composition of 28%, followed by plastic waste of 28%. The wastes had moisture content of 47 %, and bulk density was 120 kg/m3. Waste separation was not successful in AIT, and the mixed wastes were found in different color garbage bins, temporarily stored at the material recovery facility, and finally sent to local Thai Municipality for final disposal. People mixed all the waste in the dormitory (usually only one bin was provided in each room in the resident area) and dropped to the bins. The plastic waste generation rate was 481.6 kg/day which was collected from three color bins. This study, however, showed that there was a potential for better separation of solid wastes. The physical analysis of the solid wastes showed that 28% of the total solid wastes generated was plastics, which showed the lack of awareness of using plastic products in AIT. In this study, the recommendation was to change from three colored garbage bin system to two garbage bin systems (only wet and day) with proper pictures of wastes posted in front of each bin. Also, number of required garbage bins by colors were provided as a recommendation for better management of garbage bin locations on AIT campus. The application of solid waste management and waste separation conducted in AIT campus could be apply to Kabul city, Afghanistan. The questionnaire survey and waste generation and composition analysis could be used to assess the current solid waste situation and provide recommendation for better solid waste management in Kabul city. |
