Abstract

Food loss and waste (FLW) valorization remains challenging due to mixed properties and composition arising from seasonal and regional variations in food production. Here we examine the capacities of 3D printing for valorizing FLW streams, with a focus on FLW-based bioinks. We consider how waste management practices, 3D printing technology and emerging FLW valorization techniques could address challenges concerning raw material sourcing, improved material printability and suitable mechanical properties. Bioink ingredients incorporating biologically active compounds derived from FLW streams could offer tailored functionalities, supporting food preservation and economic, health and environmental sustainability benefits in line with the Sustainable Development Goals. © Springer Nature Limited 2025.
