Using GIS to Determine Waste Transfer Stations in Relation to Location of Landfill Sites in the Accra Metropolis | Chapter 4 | Modern Advances in Geography, Environment and Earth Sciences Vol. 5

 Accra's existing landfill sites are exceeding capacity, and land acquisition for landfill construction has become extremely difficult as a result of the city's fast development. However, given the current rate of expansion, an intermediate facility is urgently needed to avoid the creation of waste sites far from the source of generation. This is the garbage transfer station, where waste is processed and compacted in long-distance vehicles (Compactor trucks) to reduce waste transport and disposal costs. The study's goal was to use a Geographic Information System to find optimal locations for trash transfer stations in relation to landfill sites (GIS). The Geographic Positioning System was used to identify the coordinates of all the shared container sites in Accra (GPS). To aid in the analysis of the data collected, the coordinates were transformed into points using ArcGIS and Microsoft Excel 2007. With the use of the GIS, four transfer stations were identified: Ablekuman and Amomola (Transfer station 1), Oblogo and Weija (Transfer station 2), Ashongman and Agbogba (Transfer station 3), and Ashaley Botwe and Ogbozdo (Transfer station 4). (Transfer station 4). At Accra, waste transfer stations have been built (in Teshie, Achimota, and Kokomlemle), however the majority of these are on ancient landfill grounds.
