Abstract
The global food industry generates substantial volumes of solid and liquid waste throughout its production, processing, and consumption cycles. Remarkably, around one-third of the world's produced food is wasted annually, amounting to an alarming 1.3 billion tons of discarded resources. Stringent environmental regulations have intensified waste management challenges, prompting a transition towards more sustainable practices. In response to this pressing issue, there is growing emphasis on extracting valuable nutrients from food industry waste to create value-added products. Formerly seen as a liability, this waste is now recognized for its untapped potential in a circular economy framework. The conversion of waste-derived nutrients into innovative products not only reduces environmental impacts but also aligns with principles of resource efficiency. This comprehensive review presents a holistic overview of diverse strategies for mitigating and managing food industry waste. Covering reduction at the source, advanced treatment methods, and waste valorization techniques, the review illuminates how stakeholders are adapting to the evolving waste management landscape. It underscores the potential of converting waste into valuable resources, thereby establishing a more sustainable trajectory for the food industry. In essence, this review synthesizes current advancements and challenges in food industry waste management. It highlights the urgency of collaborative efforts among industry, policymakers, and researchers to devise and implement innovative strategies. These strategies aim to not only alleviate waste burdens but also unlock its inherent value, contributing to a more sustainable and resource-efficient future.
