Solid waste management plan for selected sectors of Islamabad using GIS techniques (T-1260) (MFN 3322)

Abstract

Solid waste is one of the most visible and pressing urban environmental problems in both developed and developing countries. Urbanization, demographic growth and economic development all contribute to the generation of waste, which overloads the capacities (budget, personnel and infrastructure) of the local authorities. If solid waste is not managed properly, it could have effect on health and environment. Geographical Information System is a latest tool that provides spatial and non spatial data in so many areas for better planning and decision making. In this study GIS tool was used to monitor existing solid waste system in the selected sectors (F-6, F-7, G-6 and G-7) of Islamabad for relocation and proper management plan. Waste generation is higher than the carry capacity of waste bins in sector G. There are 15 extra trolly and 7 skips in sector F-6 that is relocated to sector G-6 and G-7 on the basis of sensitivity like school, hospitals and markets. There are 46 trolly that have been reallocated within the sector F-6 according to the buffer analysis of sensitive areas and waste generation pattern. In sector F-7 there are 10 extra trolly and 4 skips, proposed for relocation in other sectors. There are 98 trolly placed in the sector G-6 with no skip. The waste generation in this sector is high so by using the GIS tool 65 trolly and 5 skips were relocated against the requirement of 79 trolly and 6 skips. There are only 23 trolly with 20 skip were placed in sector G-7 which is the highest waste generating sector among the selected sectors, so on the basis of analysis the required number of trolly is 224 and 14 skips. By using GIS tool 90 trolly and 14 skip has reallocated within the sector G-7 against the waste generation and population density.
