Abstract:

Landfilling is one of the most effective and responsible ways to dispose of municipal solid waste (MSW). Identifying landfill sites, however, is a challenging and complex undertaking because it depends on social, environmental, technical, economic, and legal issues. This study aims to map the optimal sites that were environmentally suitable for locating a landfill site in Butuan City, Philippines. With reference to the policy requirements from DENR Section I, Landfill Site Identification Criteria and Screening Guidelines of National Solid Waste Management Commission, the integration of a Geographic Information System (GIS) model builder and Analytical Hierarchy Process (AHP) has been used in this study to address the aforementioned challenges related to the landfill site suitability analysis. Based on the generated sanitary landfill suitability map, results showed that Barangay Tungao (1131.42967 ha) and Florida (518.48 ha) were able to meet and consider the three (3) main components, namely economic, environmental, and physical criteria, and are highly suitable as landfill site locations in Butuan City. It is recommended that there will conduct a geotechnical evaluation, involving rigorous geological and hydrogeological assessment employing a combination of site investigation and laboratory techniques. In addition, additional specific social, ecological, climatic, and economic factors need to be considered (i.e. including impact on humans, flora, fauna, soil, water, air, climate, and landscape).
