S. Korean researchers reveal method of using fat insects in producing eco-friendly biodiesel

South Korean researchers announced a method of producing environment-friendly fuels by utilizing the remains of high-fat black soldier flies.

The method uses leftover fat from black soldier flies to produce animal feed, which is converted into the energy source through a purification process.

The finding, published in the online edition of Environmental Engineering Research, is expected to support South Korea's efforts for carbon neutrality by 2050.

The Korea Petroleum Quality & Distribution Authority (K-Petro) noted that black soldier flies have a great potential to be used for biodiesel production as it feeds on food waste and has a high-fat content.

K-Petro added that South Korea spends around 800 billion won annually to handle 5.5 million tons of food waste, the use of black soldier flies could be of help.

South Korea depends on imports for around 70 percent of materials used to produce biodiesel products, and the new method will help the nation become more self-sufficient in its energy needs.

The institute hinted that mass production will be possible once there is enough supply of black soldier flies.
