Decision Support Tool Process Module for Municipal Solid Waste Processing for Developing Countries

The MSW decision support tool refers to the Municipal Solid Waste Decision Support Tool (MSW DST), a software model co-developed by the U.S. Environmental Protection Agency (EPA) and RTI International. Dr. Ketan Shah, a professional with SCS Engineers, has been involved in the development and application of specific process modules for this tool, particularly those related to MSW collection, transportation, and greenhouse gas (GHG) emissions, with a focus on developing countries.

About the MSW Decision Support Tool
The MSW DST is a customizable computer model designed to help solid waste planners, city managers, and local governments evaluate the economic and environmental aspects of integrated waste management strategies.

About the MSW Decision Support Tool Study

Authors Ketan Shah, Ph.D., SCS Engineers, and Melanie Sattler, Ph.D., P.E., Professor, The University of Texas at Arlington, on a Solid Waste Assessment Tool (SWAT), which contains a solid waste management processing module prevalent in developing countries. Then use the processing module to compare case studies of two municipalities in Gujarat State, India: Ahmedabad Municipal Corporation (AMC) and Vapi Municipality (VM). The study results include determining an optimal waste management system (types of waste processing) to minimize GHG emissions, costs, and diesel consumption. [1]

Key features and uses of the tool include:
  • Life Cycle Assessment: It uses a life-cycle approach to quantify costs, energy consumption, and environmental releases (including air and water pollutants and GHGs) for various waste management activities.
  • Scenario Analysis: Users can simulate existing waste management systems and analyze new proposed systems or alternatives (e.g., source reduction, recycling, composting, waste-to-energy, landfilling) to make informed and defensible decisions.
  • Customization: The tool can use embedded North American default data, or users can input site- or region-specific data for a more localized analysis.
  • Policy Support: It helps decision-makers evaluate options for meeting policy goals, such as landfill diversion targets or carbon emissions reductions.
