Evaluation of landfill site choice using AHP and GIS case study: Oum Azza, morocco

Abstract

The amount of household waste produced by the mainly urban population in Morocco continues to increase year after year. Morocco is thus confronted with the problems of storage and disposal of this waste, which are composed largely of organic matter, bio-waste. In the recent past, these wastes have been buried in wild dumps or in old quarries located in areas close to urban centers without any treatment or control. This can constitute significant risks both for public health and the environment and for the future of the socio-economic activities of the country. For which evaluating municipal landfills is vital due to the importance of health and environmental issues and the possibility of contravening environmental and engineering criteria and principles. The present research is conducted using new techniques of approach among others, the analytical hierarchy process AHP, which will allow us to weight and combine all criteria and to classify their respective weights, as well as the use of GIS which will contribute to the evaluation of these criteria in order to determine whether the choice of the current site according to the results of our study meets the requirements of a controlled landfill respecting the environment.

Evaluation of Landfill Site Suitability Using GIS, Remote Sensing, and the Multi-Criteria Decision-Making (AHP) Approach, Ethiopia

“…However, land lling is one of the most common preferred methods for disposal (Taghi et al, 2015). This is because it is easy for operation, low cost, less technological involvement, and less environmental effect (Errouhi et al, 2018;Randazzo et al, 2018).…”

“…Researchers investigated the negative impacts of the inappropriate land ll site (Leao et al, 2001;Errouhi et al, 2018). Because of the numerous elements that must be taken into account, planners and authorities view the site of land lls as a hard task.…”

Geographic Information System (GIS) for Landfill site selection - A review

“…One of the most frequent types of pollutants in the environment is solid waste, some of which, like plastics, wood, metals, and glass, may take a very long time to break down. Although some nations recycle or incinerate a large portion of their waste, because sanitary landfilling is required for the storage of burnt-out garbage and the remains of recycling procedures, landfill disposal of solid waste is still necessary, even though a variety of techniques, including landfilling, incineration, and manure, have been used to manage solid waste, landfilling remains one of the most popular methods this is due to the method's simplicity and affordability, which makes it ideal for developing nations [2]. The landfill location is naturally influenced by several factors, making the choice extremely challenging for decision-makers.…”

The choice of optimal sites for controlled landfill using the Analytical Hierarchy Process and the Geographic Information System: A case of Oum Azza in Morocco

“…The country is thus confronted with the embarrassments of waste management which is composed largely of organic matter. Subsequently, this waste was buried in illegal landfills or in old quarries located in areas close to urban centers without any treatment or control, this has posed significant risks for both public health and the environment as well as for the future of the socio-economic activities of the country [1].…”
