A circular economy model for waste management in India

Abstract

Management of waste is one of the major challenges faced by many developing countries. This study therefore attempts to develop a circular economy (CE) model to manage wastes and closing the loop and reducing the generation of residual wastes in Indian municipalities. Through extant literature review, the researchers found 30 success factors of CE implementation. Using the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) SIMOS approach, the rating and weight of decision makers (DMs) for each factor were collected. A structured questionnaire has been developed incorporating all these 30 factors, to extract the most important factors. The data was collected from top 10 officials (DMs) from the Chennai municipality, who handle three regions (metropolitan, suburbia and industrial). Based on the TOPSIS SIMOS analysis, nine CE implementing factors (critical success factors (CSFs)) among the 30 variables that were significant based on the cut-off value was identified. A CE model has been proposed based on these nine CSFs for waste management in India.

Transition and Implementation of Circular Economy in Municipal Solid Waste Management System in Nigeria: A Systematic Review of the Literature

“…The implementable variables of CE are maintenance and repair; separation technologies; digitalization-such as generating real-time data about the availability, location, and composition of MSW to boost efficient traceability and collection by service providers; urban planning [38]; service provider support for raw materials; the marketing of recoverybased products; refurbishment; the value measurement of commodities; logistics and supply chain management; and the recycling of waste products [39]. Because waste is generated from materials or products, beyond the 3Rs of reduce, reuse, and recycle, the 12Rs of circularization, which are refuse, reduce, reuse, repair, refurbish, renovate, return, recycle, recover, re-manufacture, redesign, and rethink, should be prioritized with the circular economy in mind [40].…”
