RESEARCH ON WASTE TREATMENT FROM HEINEKEN VIETNAM BREWERY LIMITED COMPANY USING BLACK SOLDIER FLY LARVA (Hermetia illucens)

Tóm tắt

This study investigates the efficacy of black soldier fly (BSF) larvae in bioconverting two types of organic waste: industrial waste (brewery spent grain) and agricultural by-product (pineapple peels), at varying substrate ratios of 100:0, 70:30, 50:50, 30:70, and 0:100. Experimental findings indicate that BSF larvae exhibit robust growth performance across all treatments. Among the tested ratios, the 70:30 mixture of brewery spent grain to pineapple peels yielded the highest efficiency, with a waste reduction rate of 87.86%, larval length of 18.6 mm, width of 5.6 mm, and a biomass conversion rate of 9.45 × 10⁻³ g d^-1. These results demonstrate the superior suitability of the 70:30 formulation for large-scale organic waste management. The study highlights the potential of BSF larvae as a sustainable, scalable solution for processing industrial and agricultural organic waste, offering significant environmental and resource utilization benefits.
