“…Regardless of the definition, food waste still needs to be managed effectively. Food waste is a threat to the world because its production is increasing every year (Mannaa et al, 2024;Naik et al, 2023) . In reality, a third of the amount of food produced is wasted or lost every year, and at least 820 million people around the world do not have enough food (Martin-Rios et al, 2021).…”

The concept of a circular economy emphasizes the principle of reduce, reuse, and recycle which is closely related to the issue of food waste management. Through the practice of the concept of circular economy in the food system, issues related to Zero Hunger emphasized in the Sustainable Development Goals can be implemented optimally. Nevertheless, the exposure and understanding of the circular economy in the field of education, especially technical and vocational education, requires this matter to be examined in more depth. The objective of the study is to explore the integration of the circular economy concept in Technical and Vocational Education and Training (TVET). The methodology used is document analysis which is the collection of information from reports and articles from past studies. General and specific keywords were used in information searches in the Scopus, Web of Science (WoS), Education Resource Information Center (ERIC) and Dimensions databases. The concept of a circular economy can be effectively integrated into TVET education through sustainable practices, resource management, waste reduction and closed-loop production processes.

“…More importantly, the obtained data are beneficial for developing future environmental protection and conservation methods. One hypothesized technique to be considered is the release of artificially bred Dhh larvae or adults with modified microbiota profiles imitating wild individuals into designated areas to facilitate material decomposition and nutrient cycling in any required habitat, such as the insect-based agri-food waste valorization [ 47 ]. Modifying the gut microbiome reduces the released specimens’ repulsive responses to a feral environment and lowers any risks of introducing foreign gut microbes into the wild population.…”

Background Although stag beetles are a popular saprophytic insect, their gut microbiome has been poorly studied. Here, 16 S rRNA gene sequencing was employed to reveal the gut microbiota composition and functional variations between wild and domestic Dorcus hopei hopei (Dhh) larval individuals. Results The results indicated a significant difference between the wild and domestic Dhh gut microbiota., the domestic Dhh individuals contained more gut microbial taxa (e.g. genera Ralstonia and Methyloversatilis) with xenobiotic degrading functions. The wild Dhh possesses gut microbiota compositions (e.g. Turicibacter and Tyzzerella ) more appropriate for energy metabolism and potential growth. This study furthermore assigned all Dhh individuals by size into groups for data analysis; which indicated limited disparities between the gut microbiota of different-sized D. hopei hopei larvae. Conclusion The outcome of this study illustrated that there exists a significant discrepancy in gut microbiota composition between wild and domestic Dhh larvae. In addition, the assemblage of gut microbiome in Dhh was primarily attributed to environmental influences instead of individual differences such as developmental potential or size. These findings will provide a valuable theoretical foundation for the protection of wild saprophytic insects and the potential utilization of the insect-associated intestinal microbiome in the future.

“…Larvae of more than 2,000 species of insects participate in such conversions and include, for instance, the larvae of black soldier flies (Hermetia illucens), two-spotted crickets (Gryllus bimaculatus), desert locusts (Schistocerca gregaria), house flies (Musca domestica), Cambodian field crickets (Teleogryllus testaceus), yellow mealworms (Tenebrio molitor) and others (see Figure 1, insert) (68-72). Insects are employed already in such processes for a number of advantages which range from being cost effective to the possibility of reducing waste odors compared to other methods (73)(74)(75).…”

The future in the litter bin – bioconversion of food waste as driver of a circular bioeconomy

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.
