Abstract: Rapid urbanization and population growth have significantly
intensified municipal solid waste management challenges, making the selection of
suitable landfill sites a critical issue for environmental sustainability and public health.
This article examines the application of Geographic Information Systems (GIS) and
remote sensing technologies for identifying alternative locations for municipal waste
landfills. The study synthesizes existing methodologies and case studies to evaluate
environmental, socioeconomic, and infrastructural criteria influencing landfill site
suitability. Multi-criteria decision-making techniques, including the Analytical
Hierarchy Process (AHP) and weighted spatial analysis, are emphasized as effective
tools for integrating diverse datasets such as land use, topography, proximity to water
resources, transportation networks, and population density. The findings highlight that
the integration of GIS and remote sensing enhances the accuracy, transparency, and
efficiency of landfill site selection, while minimizing potential environmental risks and
social conflicts. The article concludes that geospatial-based approaches provide a
robust scientific framework for sustainable municipal waste management and support
informed decision-making aligned with long-term urban development and
environmental protection goals.
