Abstract
Saskatchewan has the highest number of landfills per capita in Canada. Given the lower population density and the skewed spatial population distribution, comprehensive analysis of municipal solid waste management systems in Saskatchewan is inherently difficult. Most of the published waste studies however focus on city-level waste management, and there is a lack of literature with respect to the rural areas. In this study, landfills and transfer stations are examined temporally and spatially using Geographic Information System. Landfills and transfer stations from 2017 and 2020 were plotted against census division land area, annual budget, and population density to study temporal changes. Saskatchewan witnessed a 54% reduction in the number of landfills and a 55% increase in number of transfer stations between 2017 and 2020. The replacement of landfills with transfer stations are more noticeable in divisions 8, 9, and 16. Regression analysis is conducted, and landfill closure operation show no obvious correlation to division land area, annual budget, or population density. Rural division 18, representing Northern Saskatchewan, has approximately 45% of the land area in the province and has the lowest population density. The findings suggest different waste management strategies are required for urban and rural areas. The results of this study will help policy makers to better implement solid waste management strategies in urban and rural areas.

IntroductionPublisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations
Unlike other waste studies focusing on specific urban centers, this study explicitly examines municipal solid waste management (MSWM) systems in both rural and urban regions
Between 2017 and 2020, the number of landfills decreased by 54% and transfer stations increased by 55% in Saskatchewan
Summary
Publisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations. Effective municipal solid waste management (MSWM) demands careful planning, prudent investment, and ongoing monitoring and quality assurance program [1]. Landfills and waste transfer stations play a more dominant role in waste treatment than incineration and other waste-to-energy technologies, probably due to air emissions and residuals such as dioxins, furans, bottom, and fly ashes associated with the municipal waste incineration process [2]. Canada has one of the highest per capita waste generation rates across the globe [3]
