A review of organic waste enrichment for inducing palatability of black soldier fly larvae: Wastes to valuable resources

Organic waste treatment with BSF is cost-effective and emits less pollution.

“Organic waste treatment with BSF is cost-effective and emits less pollution [34].”

This production approach has a social stigma that forbids the consumption of organisms.

Once BSFL has reached maturity, its biomass can be collected and used as a feedstock for proteins, lipids, and other biochemical syntheses.

“Once the BSFL has reached maturity, its biomass can be collected and used as a feedstock for proteins, lipids, and other biochemical syntheses [65].”

In-situ fermentation increases BSFL growth rate, survival rate, and waste-to-biomass conversion in wastes rich in fibre and lignocellulosic wastes, for greater digestion and nutrient assimilation into BSFL bodies.

“According to Raksasat et al. [65], the benefit of in-situ fermentation is that it increases BSFL growth rate, survival rate, and waste-to-biomass conversion in wastes rich in fibre and lignocellulosic wastes, for greater digestion and nutrient assimilation into BSFL bodies.”

Hydrolysis via microbial fermentation breaks down complex components of organic matter while BSFL populations in the wild decompose decaying organic matter.

“The hydrolysis process via microbial fermentation breaks down the complex components of organic matter while the BSFL populations in the wild decompose decaying organic matter [65,69].”

BSF larvae must access the epidermal layer of plants before consuming difficult-to-digest complex organic compounds such as lignocelluloses.

“BSF larvae must access the epidermal layer of the plants before consuming the often difficult-to-digest complex organic compounds, such as lignocelluloses [65].”

Dry waste such as rice bran, palm kernel expeller, and soybean curd residue can be added to control organic waste with high moisture content.

“Alternatively, dry waste, such as rice bran, palm kernel expeller, and soybean curd residue can be added to control organic waste with high moisture content [65,66].”

Adding or blending the main substrate with rich-nutrient and low-cost discarded organic waste could improve nutritional balance, such as C/N ratios and pH value of the substrate, and improve BSFL rearing efficiency.

“Therefore, adding or blending the main substrate with rich-nutrient and low-cost discarded organic waste (for example, palm kernel expeller and soybean curd residue) could improve nutritional balance, such as the C/N ratios and pH value of the substrate, and improve BSFL rearing efficiency [65].”
