Solid Waste Disposal

Waste is any substance or material which is discarded when it is not useful anymore. Compared to the most commonly used methods such as recycling, waste transformation and source reduction in managing solid waste, sanitary landfilling has been identified as an appropriate method to eliminate waste in an economical and environmental friendly manner. However, finding a suitable area for siting a landfill is challenging due to incorporation of various factors and regulations. As the rate of people migrating from rural areas to cities is increasing, thus cities are expanded and therefore result in more waste production. For example, the Akure city which have developed and the number of waste has increased. Thus, a competent and suitable area is needed to dispose waste more safely. According to Anifowose, Omole and Akingbade (2011), other researchers suggested that the best waste disposal site should meet specific criterias or requirements such as; it should be located close to the source of the waste, have suitable transport accessibility, not situated in low-lying areas or floodplain, and it should be underlain by geologically stable and strong rock material. Decision-making in siting a sanitary landfill includes many variables from various data sources; therefore Geographic Information System (GIS) is a perfect tool to be used as it can …show more content…

Field work should be carefully done to identify potential site for sanitary landfill-type waste disposal. Furthermore, a Multicriteria Decision Analysis tool allowed for optimal site identification and design, reducing the effect toxic from disposed waste on the atmosphere, biosphere and hydrosphere which also reduces gases causing climate change. GIS analysis is very good to identify optimal areas although there is a need for geotechnical and hydrogeological analyses in final site
