The European Commission has approved the use of insects as animal feed in the EU, a move adopted by Denmark with the aim to reduce soybean imports. Danish researchers are focusing on the black soldier fly as a potential replacement for 10% of imported soybeans by 2024. These insects are efficient in converting waste products from breweries and dairies into protein, with one gram of eggs hatching into 30,000 larvae. Researchers at the University of Aarhus are now working on optimizing the diet of the flies to improve efficiency and decrease nitrogen emissions.
