El El-Gizawi Recently, the transformation of existing cities into smart cities has become an urgent necessity to solve urban problems by linking the dimensions of sustainability with information and communication technology to enhance the quality of life. The current research problem lies in the rapid increase in urban population growth, the increase in resource consumption over the past few decades, and the increase in migration rates from the countryside and neighboring villages to urban cities, which lead to an increase in the problem of solid waste management. Conventional waste management systems are not equipped to handle the excess waste generated by a growing population. To help bridge the gap, societies need to adopt smart waste management solutions that increase efficiency and reduce collection costs. Hence, transforming the solid waste management system into a Smart solid waste management system has become an urgent need for solid waste collection and treatment to achieve the Sustainable Development Goals (SDGs), especially in developing countries. Therefore, the study adopts examining the performance of East Mansoura city as a case study in the field of solid waste collection and treatment. To achieve the objective of this study, the key performance indicators for smart sustainable cities KPIs for SSC that were developed by the ITU and related to the collection and treatment of solid waste were adopted to measure and evaluate the current situation for the selected case study. Finally, an action plan was proposed to transform the waste management system in East Mansoura into a smart waste management system. 2023 2023 08 21 10.54216/IJBES.060101 https://www.americaspg.com/articleinfo/22/show/1568
