Abstract
Municipal Solid Waste Management System (MSWMS) of Jalalabad city, Afghanistan was assessed in order to investigate its weakness and develop a new system based on the outcomes of the assessment. The results revealed an 81% dissatisfaction of people with regards to lack of proper waste management planning and infrastructure. Waste storage, collection and treatment and final disposal were found to be the weak links in the system. The city generates 200 ton waste per day with a generation rate of 0.37Kg/capita/day. A total of 211 collection points were estimated to be necessary assuming 100% service coverage in the entire city. Collection routes were optimized using Network Analyst tool in ArcGIS. Cost of collection per ton of waste was analyzed and estimated using two scenarios: Baseline scenario-vehicle’s travel time and loading/unloading time was considered (2.9USD/ton) and congestion scenario- in addition to vehicle’s travel time, idling time was also considered (3.3USD/ton). Sanitary landfill operation lifetime was calculated for 11 years (period: 2017-2027) for which a cumulative 7.7 hectares was estimated to be necessary. Cost of waste disposal required was estimated as 5.7USD/ton. Hence, the modeled system’s cumulative cost was calculated as 9USD/ton, which is 34% less than the current cost
