Australian scientists have genetically engineered black soldier flies to eat organic waste and produce ingredients for making everything from lubricants to biofuels to high-grade animal feeds. The fly larvae can eat double their body weight a day, consuming waste faster than microbes. They are harvested once they turn into pupae. The scientists have created a company to commercialize their work - they hope to have their first genetically engineered flies for use in waste facilities by the end of the year.
