LEAN SEIS SIGMA NA INDÚSTRIA DE ÓLEO DE SOJA: ESTRATÉGIAS PARA REDUÇÃO DE DESPERDÍCIOS E OTIMIZAÇÃO DO RENDIMENTO DO FARELO

Abstract

This study analyzes the operational routines of preparation and extraction in a company under the Lean Six Sigma approach, aiming to evaluate the efficiency and sustainability of the production system in the soybean processing industry. The adopted methodology is based on the application of the DMAIC cycle (Define, Measure, Analyze, Improve, and Control), integrated with chemical production engineering, emphasizing automation, real-time monitoring, and standardization of operational routines. The results indicate high control over critical process variables, effective use of performance indicators, statistical control, and energy recovery, which contribute to maximizing meal yield and minimizing waste. Furthermore, the fundamental role of operator engagement and leadership in maintaining a culture of continuous improvement is highlighted. It is concluded that the systematic implementation of Lean Six Sigma constitutes a viable and effective solution for operational optimization, cost reduction, and compliance with environmental requirements, with potential for replication in other units within the agro-food sector.
