Black soldier fly larvae have (Hermetia illucens) emerged as a promising sustainable protein source for animal feed. However, their commercial-scale production often relies on costly feedstocks. This study investigates the feasibility of incorporating biological waste from juice production into larval diets. The objective is to determine the optimal inclusion rate of this waste, up to 30%, without compromising larval growth, development, and nutritional quality. By evaluating larval biomass, survival rates, and nutrient profiles, this research aims to contribute to the development of more cost-effective and environmentally friendly BSFL production practices.
