Selecting the Suitable Waste to Energy Technology for India Using MULTIMOORA Method under Pythagorean Neutrosophic Fuzzy Logic

Abstract

Municipal solid waste (MSW) development has increased on a global scale, posing significant socioeconomic and environmental challenges. Waste to energy conversion is strategic because it can determine the
best waste-to-energy technology. Recognizing the significance of waste in energy selection, this research aims
to select the best technology based on its eco-friendliness. A two-phase methodology is used for presenting a
framework for waste to energy technology selection. The first phase involves the selection of criteria for this
problem and the perspectives of decision makers. Ranking the selected criteria using a novel SWARA method,
and ranking the technology of WtE with respect to selected criteria weights are obtained. In this paper, we
investigate the WtE technology problem using the novel concept of the Pythagorean Neutrosophic fuzzy set
(PNFS). This set is a hybrid of the Pythagorean and Neutrosophic fuzzy sets. In this paper, we propose the best
WtE technology for India. We employ the MULTIMOORA method in the Pythagorean Neutrosophic fuzzy
environment for this purpose. Sensitivity and comparison analyses are also performed to ensure the framework’s
robustness. The findings of this study are useful in ranking the technology, and as a result, waste management
can replicate the proposed framework for waste disposal for their new platform.
