Optimization of the management of household and similar waste collection: Case of the city of Taroudant (Morocco)

Abstract

The collection and the transportation of waste are considered ones of the main tasks that the municipality undertakes and this task requires a lot of expenses, that's why this mission has to be managed well. Unfortunately, such as the case with Taroudant city. In this context, this study was carried out in order to suggest better strategies of collecting waste with the possibility of reducing the cost if an effective management plan is followed. The Geographic Information System (GIS) is the tool applied in this study, this provides an advanced and enhanced modeling framework for decision makers, it allows the analysis and the stimulation of various aspects of waste management. The objective is to achieve better optimization of the distance traveled and to reduce the time for collection circuits such as household or similar waste. However, the main goal is to improve the efficiency of waste collection and transportation, while at the same time increasing the efficiency of waste collection rates through bin reallocation and the introduction of new collection routes. So, the project's methodology deals with all the information, such as the orientation of the road routes, the spatial distribution of the inhabitants, the location of the containers and their coverage radii. In order to have the different proposals of the optimized and profitable scenarios of household waste collection. The main results of the study show that the proposed scenarios significantly improve the efficiency of CO₂ emissions and fuel consumption, this is due to a 20.43% decrease in time and 19.64% decrease in distance traveled. As a result, there will be significant cost reductions compared to the current practical situations of waste management in the city of Taroudant.
