As the global demand for food continues to rise due to increasing urbanisation, the milling industry faces the challenge of balancing efficiency with sustainability. Energy consumption, waste reduction, and digitalisation are key factors in ensuring a resilient and responsible food system.
Bühler, a global leader in milling technology, is investing significantly in innovation and research to help mills adapt to a rapidly evolving landscape.
Marco Sutter, managing director of Bühler Southern Africa, said energy consumption is a major concern in milling operations, but Bühler is tackling the challenge head-on through advanced equipment, automation, and digital monitoring tools.
Improving energy efficiency
“Bühler is committed to making milling more energy-efficient while maintaining high operational performance. Our solutions allow mills to reduce energy costs and ensure long-term sustainability.
“Digitalisation plays a crucial role in improving energy efficiency. By leveraging real-time monitoring, predictive maintenance, and AI-driven process optimisation, Bühler enables mills to reduce excess energy consumption and streamline operations. Case studies highlight the impact of these technologies, with mills achieving energy savings of up to 15%,” Sutter said.

According to Sutter, to further minimise food loss, Bühler integrates precise sorting technologies, optimised cleaning processes, and real-time milling parameter tracking.
“We support mills in adopting circular economy principles by designing machines that recover valuable byproducts and utilise recyclable materials. Sustainable sourcing and production practices are crucial for long-term resilience.
“We believe that sustainability and profitability can go hand in hand. Our goal is to provide solutions that not only reduce waste but also enhance efficiency and profitability for milling businesses,” he said.
Digital transformation crucial
Sutter explained that localised manufacturing is another key strategy in improving sustainability. “By reducing transportation emissions and strengthening regional food security, our approach ensures faster service and maintenance while enhancing supply chain resilience.
“Smart milling is the future, and we are leading this transformation. Our digital solutions empower mills with real-time insights, allowing them to make data-driven decisions that enhance efficiency and sustainability.”
Transparency in the food supply chain is becoming increasingly important, and Sutter said their smart technologies enable enhanced traceability through blockchain integration. From farm to finished product, these innovations support accountability and food safety in milling operations.
He noted that the rapid advancement of technology in milling required a highly skilled workforce, and they are committed to knowledge-sharing and capacity-building through its African Milling School.
“Training and skills development are key to future-proofing the milling industry. We invest in education to ensure millers are well-equipped to handle new technologies and industry shifts.
“We are leading this effort, ensuring the next generation of millers is equipped with the skills needed for a sustainable and efficient industry,” he said.
