Logística reversa e gestão de resíduos sólidos: um estudo de caso em uma instituição federal de ensino multicampi

Abstract

In pursuit of a sustainable future, educational institutions play a fundamental role in promoting practices that preserve the environment and prioritize sustainable development. Understanding how these institutions manage solid waste and reverse logistics is essential to inspire societal change. In this context, the aim of this study is to analyze the management of solid waste and reverse logistics at IFSULDEMINAS - Federal Institute of Education, Science, and Technology of Southern Minas Gerais, a federal multi-campus educational institution, identifying best practices and areas for improvement to be expanded across its campuses. Thus, this research identified successful actions, as well as improvements and corrections, focusing on the analysis of the eight campuses of IFSULDEMINAS. The interest in this research stems from IFSULDEMINAS being recognized as one of Brazil's most sustainable educational institutions according to the international UI GreenMetric World University Ranking. Therefore, the research is relevant in identifying and analyzing the practices of solid waste management and reverse logistics adopted by IFSULDEMINAS, with the intention of replicating these successful practices across its campuses. The study was conducted using the case study method with a qualitative approach. Considering the objectives and stages of this research, based on a diagnosis of the situation of this multi-campus educational institution, actions were identified that promote and drive solid waste management and reverse logistics through the development of an Opportunities Matrix using the Analytic Hierarchy Process (AHP). As a technical outcome of the research, an Action Plan was proposed with actions classified according to their priority for implementation. As part of the objectives of this work, processes classified as high priority were mapped using Business Process Model and Notation (BPMN). This study concluded that some campuses have higher volumes and diversity of waste, highlighting the need for more incentivized and monitored actions. Additionally, some campuses demonstrate greater effectiveness in solid waste and reverse logistics management, while others face greater challenges in specific types of waste. These disparities underscore the need for tailored actions and strategies to optimize sustainable practices across all campuses of the institution. Therefore, through the Action Plan, it is possible to leverage environmental initiatives, promoting efficient management throughout IFSULDEMINAS, which can be replicated and adapted for other educational institutions.
