초록

This study aims to quantify the environmental benefits derived from producing compost and dried larvae of black soldier fly (BSF), as well as decomposing 1 ton of food waste using BSF larvae. This analysis is compared with the production of aerobic compost and dry single ingredient feedstock through conventional food waste recycling methods, employing life cycle assessment methodology. The findings reveal that the environmental impact of food waste decomposition using BSF larvae is reduced by 88.4% compared to the production of dry single ingredient feedstock and aerobic compost. The emissions of C2H4, trifluoromethyl bromide, SO2, CO2, phosphate, and antimony were reduced by 99.6%, 95.5%, 88.5%, 88.4%, 86.0%, and 80.6%, respectively. In the case of CO2, assuming the national food waste discharge, the reduction effect amounted to 1.87 million tons of CO2-eq. This is equivalent to the amount of greenhouse gases absorbed annually by 800 million pine trees and 530 million oak trees. Although this study has certain limitations as it relied on estimated figures obtained through the allocation of utilities for optimal BSF breeding, the findings of this study can serve as valuable data for management and policy support data in related industries. The production of compost and dried BSF's larvae through BSF treatment offers a quantified reduction in environmental impacts caused by replacing aerobic compost and dry single ingredient feedstock with common food waste recycling treatment. This suggests the possibility of derivative research through a more sophisticated data collection process in the future.
