jismart2023047: Black Soldier Fly’s Role in Circular Economy through Organic Waste Recovery

Abstract

The growing human population contributes to the increase in food demand, which in turn leads to an increase in the volume of organic waste produced in the environment and a threat to human health. Anaerobic digestion, incineration, and landfill disposal are the main methods used to handle organic waste, including food waste; however, new environmentally friendly techniques are required. Over the past few decades, there has been a strong focus on the management and valorization of waste, or the development of an integrated, sustainable waste management strategy. Black soldier fly (Hermetia illucens) larvae are an inexpensive, environmentally friendly way to treat organic waste that is gaining popularity across the globe due to its affordable and self-sustaining technique that creates value-added goods and encourages high resource recovery, opening new market opportunities for the industrial sector and entrepreneurs in poor nations. It has been demonstrated that black soldier fly larvae (BSFL), Hermetia illucens, can transform organic waste into premium nutrients such as protein (up to 40%) for pet food, fish and poultry feed, and leftover fertilizer- frass with more than 3% in Nitrogen (N) content, 4% in phosphorus (P2O5) and 0.5% in potassium (K2O) for soil amendment. This paper reviews an in-depth understanding of the benefit of resource recovery from organic waste by summarizing the application of BSFL treatment.
