Selecting the Best Municipal Solid Waste Management Techniques in Nigeria Using Multi Criteria Decision Making Techniques
While developed countries use a variety of methods to convert municipal solid waste into various products such as energy, fertilizer, heat, and others, developing countries continue to struggle with municipal solid waste. Because of the various criteria to be considered, assessing these methods and determining which ones are best suited to the conditions of each country is a complicated task. The hybrid GREY-EDAS model was utilized in this study to evaluate waste treatment alternatives in Nigeria. The study employed seven distinct criteria relating to the environment, society, and cost, with the cost criterion being the most relevant. Subsequently, four waste treatment methods were evaluated: incineration, composting, sanitary landfills, and anerobic digestion. As a result, composting is proven to be the most effective. Sensitivity analysis was carried out by varying the weight of the criterion in seven distinct scenarios, and the model produced consistent findings.
