Odor-aided Analysis for Landfill Site Selection: Study of DOKAP Region, Turkey

Abstract

In our world, with the increase of factors such as the rapid and irresponsible consumption of natural resources, man-made environmental disasters, global warming, and pollution of water resources, solid wastes have to be stored or disposed of more effectively. The presentation of the data required to solve spatial problems such as storage, management, and location selection can be carried out extensively and effectively using geographic information systems (GIS). On the other hand, the unsatisfactory results obtained with GIS recently have made it mandatory to use spatial multiple-criteria decision-making (S-MCDM) methods that include the decision-makers in the process. In this study, RSWSA site selection was carried out in eight cities under the responsibility of the Eastern Black Sea Project Regional Development Administration (DOKAP). A combination of GIS and S-MCDM was used in this site selection process. A total of eight data layers were used in the site selection application. Afterwards, storage areas determined as suitable via GIS analysis underwent additional evaluation, taking into account geological, seismic, and environmental factors as well as transportation costs. In addition to these multi-component evaluations, odor analyses were carried out on the proposed storage areas using the prevailing wind direction.
