GREEN SUPPLY CHAIN NETWORK DESIGN TO STUDY THE EFFECTS OF WASTE MANAGEMENT ON ENVIRONMENT

Abstract

Waste management has become a crucial topic in modern civilization due to its negative environmental implications. This research focuses on the development of a green supply chain network for waste management, with an emphasis on incorporating environmental sustainability into decision-making. Waste management is necessary for environmental sustainability and it has impact on health of citizens and GDP of a country. The goal is to reduce the environmental impact of waste disposal while increasing resource recovery and recycling. The proposed green supply chain network design has three objectives of minimizing cost of transportation, minimizing GHG emissions due to transportation and maximizing saving of emissions due to waste management activities. The proposed model is multi-objective that take multi period into consideration. Interactive multi-objective fuzzy programming is used to optimize the model and study the results. The methodology is compared with goal programming to study its results and comparing the results of both methodologies. Various scenarios are discussed to study the effect of waste segregation as well. Higher the segregation of waste, emissions saved also increases. This study also mentions the importance of segregation of waste at consumer level. For future practice study on wet waste and food waste is also suggested with the dry waste.
