Optimizing management in Bihar: A multi-faceted approach

Abstract

The case study of waste management issues in Bihar, carried out in this study, brings out that the complex waste management problem can be dealt with in a comprehensive manner by using several strategies. This paper presenting a Mathematical Optimization Model MOP that includes several objectives including energy production, greenhouse gas emissions, material recovery, cost, job creation, and wastewater generation as a framework for assessing the WM strategies. This study translated the MOP into an SOP and used Matlas to look for Pareto-optimal solutions; it proved that incineration and composting are two technologies with advantages. Incineration has relatively high performance in energy production compared to source reduction while composting gives better material return and cost optimization. The use of the ELECTRE method for decision-making help to narrow down the decision’s evaluation allowing to give precise policy and practice indications. This approach recognises the fact that waste management, thus needs to be fluid and systematic in Bihar.
