Mapeamento de processos para a identificação de pontos críticos da logística reversa do óleo lubrificante usado ou contaminado: um estudo de caso

Abstract

The proper management of Used or Contaminated Lubricating Oil (UCLU) is essential to minimize environmental impacts and ensure the efficiency of reverse logistics. This study aims to map the logistical processes of a UCLU collection company in the state of Ceará, identifying challenges and proposing improvements to optimize operations. The research was conducted through a case study with a descriptive and quantitative approach, analyzing the processes of collection, separation, quality testing, and oil destination. The results showed that factors such as seasonality and collection models directly influence the quality of the collected material, requiring strategies to reduce impurities and improve the efficiency of re-refining. Among the proposed solutions, the implementation of contaminant detection tools, customer loyalty strategies, continuous quality monitoring, and an incentive program for collectors stand out. Thus, this study contributes to the improvement of UCLU reverse logistics, promoting greater sustainability and efficiency in the sector.
