<p>Finger millet, a climate-resilient and nutrient-dense grain, is garnering global attention for its potential in addressing food and nutritional security. Despite its high calcium, dietary fibre and polyphenol content, underutilization and poor market penetration remain challenges due to limited processing innovations and product diversification. This article explores a circular economy approach to finger millet processing, focusing on sustainable strategies that enhance value addition, minimise waste production and integrate consumer markets more effectively. The article delves into emerging product development trends like gluten-free foods, ready-to-cook, ready-to-eat formulations and nutraceutical applications. Fortification strategies to combat micronutrient deficiencies are also discussed. The paper also discusses the recent advancements in processing technologies, emphasising how thermal and non-thermal interventions, nanotechnology and digital tools are revolutionising the sector. Furthermore, the manuscript highlights smart and sustainable processing models, including waste valorisation, bioprocessing and recovery of high-value bioactives from by-products, while uniquely integrating perspectives on artificial intelligence, advanced encapsulation techniques and circular economy principles to underscore their synergistic role in shaping the future of millet research and sustainable food systems.</p>
