RONALDO MESSIAS CORSINI

Lead the complete industrial operation of a major sugar and ethanol complex processing approximately 3 million tonnes of sugarcane per harvest, producing approximately 200,000 tonnes of sugar and 100,000 m³ of ethanol.

• Lead the integrated industrial agenda across production, process, maintenance, engineering, utilities, HSE, CAPEX/OPEX, logistics and operational performance.
• Manage an organization of approximately 300 employees, reaching approximately 500 including contractors during peak and off-season activities.
• Directly lead seven senior functional leaders across production, process engineering, maintenance, utilities, quality/laboratories, logistics and PCM.
• Improved industrial availability from 96% to 98% and efficiency from 88.2% to 91.0%, moving the operation into the 1st quartile of industrial performance and cost within Raízen.
• Increased sugar mix from 46% to 53%, strengthening portfolio flexibility and value capture.
• Developed and implemented a Grade B ethanol strategy, reaching approximately 60% of production and creating an estimated premium opportunity with approximately one-year payback.
• Strengthened operational risk management, reliability strategy and CAPEX prioritization while reinforcing field-based safety leadership, contributing to 500+ accident-free days.
• Developed successors and strengthened leadership capabilities across the industrial organization.
• Led cross-functional execution across Industry, Agriculture, Commercial, Engineering and Corporate areas.

Led the complete industrial operation of a sugar and ethanol plant processing approximately 2.5 million tonnes of sugarcane per harvest, with approximately 200 employees.
