Black Soldier Fly (Hermetia illucens [L.], Diptera: Stratiomyidae) larvae (BSFL) production from food waste is gaining interest. Food waste, a heterogeneous mix of agro-food and catering leftovers serves as a challenging feedstock for BSF growth due to its varying nutrient composition. BSF, are classified as polyphagous insects with a digestive system featuring midgut for digestion and nutrient absorption. The conversion of food waste by BSFL is heavily influenced by Enterococcus, Klebsiella, Morganella, Providencia, and Scrofimicrobium, which play a vital role in substrate utilization. These microbes determine growth patterns, longevity, oviposition, and egg hatchability, which are intricately tied to the sugar and protein content of their dietary substrates. Pre-treatment techniques including hydrothermal treatment, ionization, pulse electric field discharge, and microbial treatment showed better efficiency in improving the wet waste biomass surface area and waste recovery ratio. In terms of environmental sustainability, a life cycle assessment (LCA) of food waste to BSF conversion facility yields a low global warming potential (GWP) score of 17.36 kg CO2 per ton of functional unit with a significant environmental impact during pre-treatment of food waste at a mass-rearing of BSFL. Therefore, this review emphasizes the digestive system, and gut microbiota of BSFL, with food waste-nutrient utilization by the BSFL. Environmentally promising steps involved in the valorization of food waste resources were evaluated in detail. This review also covers the international regulations involved in food waste fed BSFL, and techno-economic assessment to optimize its valuable nutrients for the new economy in waste management with less environmental footprint.

Pollinator conservation schemes are typically focused on conserving existing-, restoring degraded- or establishing new wild bee habitats. The effectiveness of such conservation schemes depends on the presence of dispersal corridors that allow habitat colonization by bees. Nonetheless, we lack an understanding of the role of semi-natural habitats edges on the connectivity of pollinator communities across intensively managed landscapes. Here, we use data from wild bee communities comprising 953 occurrences from 79 species of non-parasitic bees, sampled at 68 locations distributed across a Norwegian and a Danish landscape to show that the proportion of semi-natural habitat edges is positively correlated to bee species richness and habitat connectivity. Specifically, we found that wild bee species richness sampled along roadsides increased with the proportion of semi-natural habitat edges within1.5 km of the study sites and with local plant species richness. We combined maps showing the proportion of seminatural habitat edges with least cost path analysis to find the most likely dispersal route between our bee communities. We find that these least cost path lengths provide better models of bee species compositional similarity than geographic distance (|ΔAICc| > 2), suggesting that seminatural habitat edges act as dispersal corridors in intensively managed landscapes. However, we also find that compositional similarity between communities depend on site-specific plant species richness stressing the importance of improving the habitat quality of edge habitats if they are to function as dispersal corridors. We discuss potential management options for improving wild bee habitat conditions along seminatural habitat edges and illustrate how maps of least cost paths can be used to identify dispersal corridors between pollinator habitats of conservation priority. Maps of dispersal corridors can be used to direct wild bee habitat management actions along seminatural habitat edges to facilitate the dispersal of bees between larger grassland habitats.
