“…In addition, their by-product, larval frass, can be utilized for producing nutrient-rich organic fertilizers [7,8]. Given their ability to recycle biowastes into valuable products/by-products with decreased environmental footprints [9,10], it is not surprising that it has been considered as "crown jewel" in waste management industry [11] and global BSF market is poised for rapid growth based on current trends [12].…”

With black soldier fly (BSF) larvae being recognized as effective waste convertors, the global market for BSF industry is projected to grow substantially in the coming decade. However, using non-waste materials in the bioconversion process increases the environmental footprint of the BSF industry [e.g.: chicken feed (CF) as primary neonatal nursery meal]. In this study, we first tested if industrial food wastes (i.e., okara, biscuit meal, dried fish, coconut.) can be substitute diets for BSF neonates. Next, we tested three formulated meals based on the nutritional properties of the well-performing nursery diets from the first test/previous literatures. In the first test, we observed significant differences in neonatal growth when food wastes were directly used as nursery meals, and the initial weight of neonates influenced the development time of the larvae, with smaller neonates exhibiting prolonged larval duration. In contrast, the formulated meals performed well in promoting the growth of neonates, and the larval development showed no significant difference by day eight in the post-nursery rearing. In summary, our findings indicate that by meeting specific nutritional requirements, formulated diets made from industrial food waste could serve as a viable replacement for CF as nursery meals, resulting in a significant boost in the sustainability of the BSF industry.

Waste from the fish processing industry can provide a profitable and sustainable business. Industrial fish by‐products can be used as raw material to produce biofuels. This work evaluates the production process, characterization, and economic analysis for the production of biodiesel and fishmeal from tilapia processing waste. It demonstrates the potential of neutralized tilapia oil as a valuable raw material for biodiesel production. It presents specific mass, viscosity, and flash point results in line with ASTM and EN standards. Different plant sizes are modeled to evaluate biodiesel economic viability. Only the largest plant size was economically viable. In this case, the net present value (NPV) of US$ 13.89 million, the internal rate of return (IRR) of 50%, and the earnings before interest and taxes (EBIT) of US$ 7.87 million/year showed that the production of biodiesel and fishmeal using tilapia waste is economically attractive. Monte Carlo simulation was used to analyse the price distribution of biodiesel and fishmeal and their effects on the plant size. A large plant size gave 100% good scenarios, whereas a medium plant size showed 25% beneficial scenarios, and small plants did not have good scenarios. In this context, the plant size can overcome risks from price variability. The economic evaluation revealed that the production scale and the factory's location influenced the project's viability directly as raw material costs are associated with transportation expenses. The study therefore indicates that not all countries with well established tilapia production can produce biodiesel in a viable and sustainable way.
