Multimoora based MCDM model to convert urban solid waste into energy under picture fuzzy environment

Since a long time, the problem of urban solid waste (USW) has been solved by recycling it into energy. However, there is a difficulty with the conversion technique which limits its application. There are many conversion technologies discussed in this study which include incineration, bio methanation, pyrolysis, and gasification. Each technology was evaluated and compared each other. The indicators used in comparison are physical requirement, chemical requirement, and the sustainable use of the technology to convert USW to energy is given specific consideration. The results of the assessment demonstrate that biological technology is most suited to transforming waste into energy with a minimal environmental impact. Other techniques like incineration, pyrolysis, and gasification are highly effective and gives efficient output but will contaminate the environment with hazardous gaseous pollutants, which would surely increase global warming and greenhouse effects.
