Description

Proper landfill site selection is the basis of preliminary landfill process in evading undesirable long-term effects. The procedure of selection must refer to approved guidelines that put into considerations the social, environmental, and technical aspects in ensuring sustainability of living hood process. This book reviews and classifies common guidelines to landfill siting criteria adopted by various international bodies. The criteria are mostly common but vary in parameters and reliant on the social-economic, environmental requirements, size and physical topography of respective countries. A hypothetical comparative study of landfill site selection is accomplished using constraint mapping technique (CMT) and Analytical Hierarchy Process (AHP) group decision making. Consecutively, the GIS Multi Criteria Evaluation (MCE) site selection model using the weighted linear combination (WLC) was incorporated. The result has shown that site selection model pertaining to landfill is influenced by preferences of criteria as well as the selection of criteria.
