Solid waste collection optimization objectives, constraints, modeling approaches, and their challenges toward achieving sustainable development goals

Solid waste collection (SWC) has been one of the growing challenges throughout the world due to the development of urbanization and uncontrolled growth of the population. It is a complex process that is expensive and requires the elaborate logistics management and in-depth mathematical computation. Hence, there is an urgent necessity to develop an efficient waste collection process while saving time, fuel, labour, maintenance costs, and carbon emissions. This goal of this is paper is to deliver a comprehensive review of the SWC system concerning solid waste collection objectives, constraints, the different optimization approaches, and models, along with their strengths and weakness. The different types of optimization objectives and constraints on SWC are highlighted towards improving solid waste collection and minimizing…
