Analysis of the Application of Black Soldier Fly in Sustainable Agriculture and Carbon Emission Reduction Potential

Abstract

Facing the dual challenges of global protein resource shortages and carbon neutrality goals, developing new sustainable protein sources has become an urgent need. The black soldier fly, due to its high efficiency in converting organic waste, is gradually becoming an important alternative to traditional feed proteins. This paper systematically reviews the practical applications of black soldier fly in areas such as poultry and aquaculture feed from an application perspective and focuses on analyzing its potential in organic waste recycling and carbon emission reduction. Research indicates that black soldier fly larvae (BSFL) are rich in nutrients, possess great potential for replacing fishmeal and soybean meal in poultry and aquaculture feed, and can significantly improve animal growth performance and gut health. Its industry chain, through methods such as waste conversion, efficient bioconversion, and low-carbon processing, holds significant advantages in reducing greenhouse gas emissions; for example, converting aquaculture sludge can avoid methane emissions and achieve a high waste conversion rate. Finally, the paper proposes recommendations regarding policy support, technological optimization, and market-oriented promotion to foster the sustainable development of the black soldier fly industry chain.
