Abstract: With a population of 7.4 billion, the world is experiencing rapid population growth, contributing to increased waste production. Landfill construction and usage have increased as a result of this exponential rise in waste generation. Selecting a landfill site is crucial to sustainable solid waste management because it guarantees that the waste produced in a community or area is disposed of safely. This study establishes an LP model for cities with high per capita waste generation that takes into account several cost considerations. Furthermore, waste management is addressed, with a particular emphasis on construction and demolition waste (CDW) and municipal solid waste (MSW) by including emission costs and the transportation cost of both of these wastes to their respective landfills. The result demonstrates how the most efficient landfill satisfying the requirements is allocated. A Python code was developed to determine the landfill allocation for MSW and CDW. Seven landfills are assigned to each city for MSW and four landfills to the cities that met the CDW constraints and optimized the total cost of 4,25,03,971, which is the lowest amount required for the process of transporting both MSW and CDW from their collection areas to their respective dumping sites. This study aids in determining which landfills require additional development to accommodate their long-term usage.
