Food waste is a critical global issue with severe economic, environmental, and social consequences. In India, approximately 40% of food produced is wasted, contributing to greenhouse gas emissions, resource depletion, and food insecurity. Young adults, as key decision-makers of the future, play a pivotal role in transforming food consumption patterns. This study examines the zero food waste mindset and practices among young adults in Coimbatore district. It identifies the level of awareness, behavioural patterns, and the barriers they face in adopting zero waste food habits. The research also explores the influence of social media, education, and household practices on their food waste behaviour. The findings indicate that while many young adults are aware of food waste issues, actual adoption of waste-reduction practices remains inconsistent. The study concludes with actionable suggestions for promoting zero food waste culture among youth.
