A promising waste management technology that has emerged within the past decade is bioconversion of with larvae black soldier fly (BSFL). Regarding purposes, hygiene central. At present, most studies on BSFL conversion have been performed in small-scale laboratory settings, and mechanisms behind documented inactivation microorganisms remain unclear. In this study, dynamics pathogens indicator organisms during food was investigated. Two trials were conducted: one mimicking a large-scale industrial setup another evaluating impact frass recirculation pathogen reduction to better understand potential role bioactive compounds frass. The results indicate observed setups also applicable systems, no significant scale inactivation. primary difference between scales increased water evaporation larger leading higher electrical conductivity Increased solid retention time through did not significantly affect but considerably improved yield per treated tonne waste. clearly show linked larval presence activity. However, specific driving effect unclear—whether due produced by larvae, physico-chemical changes induced their activity, or combination both. Future research should focus microbial risks associated long-term further explore balance biological chemical factors.
