“…Among this, Food waste contributes a big chunk of it (Pour & Makkawi, 2021). Hence, it has been an interest area for researchers to understand how to manage food waste and upcycle it to a useful application such as energy generation, biofuels, or biodegradable bi products like polymers etc (Sharma et al, 2022) There have been some studies around the life cycle assessment of food waste and its eventual conversion into useful energy using traditional methods, modern valorization techniques, and studies comparing the two methods (Cremiato et al, 2018; Evangelisti et al, 2014; Fei et al, 2021; Fusi et al, 2016; Whiting & Azapagic, 2014). More focus has been on Anaerobic Digestion methods and their socio‐economic and environmental impact (Cakar et al, 2020; Jeswani et al, 2021; Scherhaufer et al, 2018; Tonini et al, 2018).…”

Recently, there has been growing interest among scholars and industry professionals in understanding how agro‐food supply chains can shift from a linear to a circular model. This involves managing waste, recovering resources, and adopting sustainable practices. However, knowledge on circular economies in agro‐food supply chains is scattered, with limited comprehensive studies available. To address this gap, our study conducts a bibliometric and network analysis of 364 documents from the Scopus database. We identify influential authors, contributing countries and journals, and most cited documents. Additionally, we use network analysis to visualize connections between authors and keywords, providing insights into emerging trends and critical research areas. We also uncover important keywords and themes, laying a foundation for future research directions. Overall, our study offers a comprehensive overview, serving as a basis for further exploration in this field.

“…Various strategies should therefore be implemented to minimize food waste, such as food sharing and donations, “lick your plate with pride” campaigns and maximizing recycling and upcycling of food waste wherever and whenever possible. By adopting these alternative approaches, individually or in concert, the environmental impact of food waste disposed in landfills or incinerated may be minimized, thereby contributing to more sustainable waste management practices ( 202 , 214 , 215 ).…”

Bioconversion of organic waste requires the development and application of rather simple, yet robust technologies capable of transferring biomass into energy and sustainable materials for the future. Food waste plays a significant role in this process as its valorisation reduces waste and at the same time avoids additional exploitation of primary resources. Nonetheless, to literally become “litterate”. extensive research into such robust large-scale methods is required. Here, we highlight some promising avenues and materials which fulfill these “waste to value” requirements, from various types of food waste as sustainable sources for biogas, bioethanol and biodiesel to fertilizers and antioxidants from grape pomace, from old-fashioned fermentation to the magic of anaerobic digestion.

“…Instead of aiming at the elimination of food waste, biological waste treatment enables beneficial food waste management. Biological processes such as composting, and biogas production are very popular solutions to increasing food waste problems as they are both economically and environmentally beneficial [19,20]. Using living organisms such as insects is another attractive food waste management technique.…”
