Abstract
The RETASTE Conference has established itself as a critical platform for advancing science and innovation on food waste management within the framework of circular economy practices. This editorial summarises the key themes and research presented at the first two RETASTE meetings, which focused on strategies such as the valorisation of food processing by-products, utilization of food waste for bioplastics, and development of waste-to-energy technologies. These studies demonstrate the potential to transform food waste from an environmental burden into valuable resources, thereby supporting both local and global sustainability objectives. The conference also highlighted the importance of integrating technology with policy and social aspects to drive transformation across the entire food system, while acknowledging the challenges that remain, including cultural, political, and administrative barriers that must be addressed for these innovations to be successfully scaled. The rebranding of the conference to “RETASTE: Rethink Food Resources, Losses, and Waste” signals a broader focus on the interconnectedness of food systems, emphasizing the need for continuous innovation and collaboration across all sectors. This editorial concludes that a holistic approach—combining technological advancements, social practices, and robust policy frameworks—is essential for effectively managing food waste and promoting sustainable food systems globally.
