In the face of increasing global demands for sustainable waste management and alternative protein sources, this study explores the industrialization potential of utilizing mealworms (Tenebrio molitor) and black soldier flies (Hermetia illucens) in urban waste management with the aid of probiotics. These insect species, rich in protein content, are recognized as valuable substitutes for traditional livestock and poultry in the search for more sustainable protein sources.

The study investigates the use of beneficial insects, specifically mealworms and black soldier flies, to process damp waste efficiently. Black soldier flies, known for their rapid growth and reproduction rates, have demonstrated their ability to thrive on organic waste materials, providing an alternative to soy-based feeds in livestock and fish farming. Challenges in scaling up the use of beneficial insects on an industrial level, including decomposition rates, survival rates, protein content, and product toxicity, have prompted research into the potential benefits of probiotics in waste digestion processes. This study explores the impact of fermenting wastewater with a combination of Lactobacillus strains (VSL#3) on decomposition rates, protein content, and toxicity of the resulting products.

The findings reveal that the addition of probiotics to waste significantly increases the protein content of insects. Furthermore, the study highlights the greater effect of VSL#3 probiotics in comparison to Lactobacillus casei, particularly in enhancing the protein content of black soldier fly larvae. These results suggest that the combination of probiotics has the potential to expedite the transition from a linear economy to a circular one, emphasizing the importance of waste pre-processing, especially for large volumes.

This research signifies a positive direction for addressing the challenges associated with urban waste management and the sustainable production of protein sources. It underscores the potential of utilizing mealworms and black soldier flies, with the aid of probiotics, as efficient tools in managing organic waste while concurrently producing high-quality protein. The study contributes to the ongoing discourse on sustainable waste utilization and circular economy practices.
