An anonymous reader quotes a report from The Guardian: A team of Australian scientists is genetically engineering a common fly species so that it can eat more of humanity's organic waste while producing ingredients for making everything from lubricants and biofuels to high-grade animal feeds. Black soldier flies are already being used commercially to consume organic waste, including food waste, but tweaking their genetics could widen the range of waste their larvae consume while, in the process, producing fatty compounds and enzymes. In a scientific paper, the team based at Sydney's Macquarie University outlined their hopes for the flies and how they could also cut the amount of planet-warming methane produced when organic waste breaks down. "We are heading towards a climate disaster, and landfill waste releases methane. We need to get that to zero," Dr Kate Tepper, a lead author of the paper, said. Dr Maciej Maselko runs an animal synthetic biology lab at Macquarie University where Tepper has already started engineering the flies. Maselko said insects would be the "next frontier" in dealing with the planet's waste management problem, which weighs in at about 1 billion tons a year in food waste alone. Black soldier flies are found in all continents except Antarctica. "If you've got a compost bin, then you've probably got some," Maselko said. The fly larvae can eat double their body weight a day and, like other insects, their larvae are used for animal feed. Maselko said the flies could already do the job of consuming waste faster than microbes. The university team has created a spin-off company, EntoZyme, to commercialize their work and hopes to have the first genetically engineered flies for use in waste facilities by the end of the year. [...] Creating a suite of genetically engineered flies would see them also produce enzymes used in animal feeds, textiles and pharmaceuticals, and fatty compounds that can be used to make biofuels and lubricants. Another proposed use is for some flies to be able to consume contaminated waste, which would then leave behind their poo that could be used as fertilizer. Tepper said flies can be engineered to deal with pollutants in several ways, including by breaking pollutants down into less toxic or inorganic compounds, evaporating them into the air or accumulating some pollutants into their bodies that can then be separated, leaving clean organic waste behind.The research has been published in the journal Communications Biology.Read more of this story at Slashdot.
