| Abstract |
The increased global demand for animal-based products results in generation of larger volume of protein-rich waste (PRW). Developing novel methods for efficient and eco-friendly conversion of these wastes is of great importance. The present study suggests a novel approach using black soldier fly larvae (BSFL) to recycle PRW treated with dietary acetic acid, which potentially reduces the NH 3 , N 2 O, and CH 4 emissions. Compared to the control, applying 2 % dietary acetic acid significantly increased the larval biomass yield and areal biomass productivity by 24.4 % and 26.3 %, respectively. The study exhibited superior biodiesel characteristics with improved cetane numbers (60.08 -61.17). The suggested route estimated reduction of the global warming potential (GWP) to 2.67 g CO 2-eq per kg dry larval biomass. There was a synergistic effect of dietary acetic acid to achieve a well-balanced diet for BSFL growth and NH 3 recycling while reducing greenhouse gases (GHGs) emissions, thereby enhancing the achievement of cleaner biodiesel production from PRW. Overall, this study provides insight into BSFL as a potential organism for efficient recycling of PRW from industrial animal byproducts for enhanced biodiesel recovery and reduced GHGs emissions, which could support the low-carbon economy and sustainability objectives. |
