Optimization of solid waste collection system in a tourism destination

most famous tourist destinations in the world. This led to a rapid increase in solid waste generation,leading to problems and challenges in solid waste collection and management. This problem is alsobeing experienced by other developing countries of the world. Despite the existence of establishedwaste management strategies, targets set for the collection of recyclable waste have not been met.This study introduces solutions to the problems and challenges faced by the waste managementsector in Hoi An city and other developing countries. This study aimed to i) optimize the map of therecovery recycling stations in an urban community, ii) develop an effective solid waste collectionsystem, and iii) provide management tools to enhance recycling activities, contributing to improvingwaste management in Hoi An city.METHODS: The RRSs were integrated into a solid waste collection system in the urban communitiesof Hoi An City, were conducted through location-allocation analysis in a geographic informationsystem environment. Routing problems of carts were solved in the combination of the reschedulingof existing solid waste collection activities in the study site. The economic evaluation by scenarioswas also calculated for ten years to assess the feasibility of scenarios.FINDINGS: Thirty-four locations were identified and optimized to accommodate the RRSs and newcollection routes. The distances travelled and working time increased in proportion to the increasein waste separation effectiveness. Waste separation is vital to the effectiveness of the new solidwaste collection system. The optimal solid waste practice model (in scenarios 2 and 4) revealedthe positive results in improving the solid waste collection system, operating economy, and localadaptation.CONCLUSION: This study redesigned the solid waste collection system to solve the current problemsin the tourism destination of Hoi An city. This study contributed as a case study of integrating urbanrecovery recycling stations into optimizing a solid waste collection system in a tourism destination.Introducing strict waste separation was the pivotal first step in systematically upgrading the solidwaste collection system in Hoi An City. This study’s findings provide government officials and serviceproviders with methods that can be applied to solve the problems faced by Hoi An city’s existingsolid waste collection and management system.
