In the present study, the effect of larval density (0, 1, 2, and 3 larvae/cm²) on the bioconversion of potato and reduction of potato peels (Solanum tuberosum) was evaluated using black soldier fly larvae (Hermetia illucens). The hatching of the eggs produced a total of 72,512 larvae per gram. The final bioconversion showed values ranging from 16.8% to 27.8%, while waste reduction ranged from 59% to 77%. The highest values for both indicators were recorded in treatments with 3 larvae/cm2. Although increasing larval density reduces the size of each individual, the presence of more larvae per unit area improves both bioconversion and waste reduction. The use of this technology allows the transformation of potato peels into organic compost and larval biomass rich in proteins and fats, which could be used for animal feed, thereby contributing to the valorization of this agro-industrial waste.
