UK startup harvests biodiesel feedstock from flies that eat food waste

In the UK, tech startup Entomics is using Black Soldier flies to digest food waste, and two weeks later the flies are ready for harvest. Acting as a conversion catalyst, their bodies produce an oil that can be transformed into biodiesel with protein animal feed and fertilizer as byproducts.  Through local entrepreneurial support programs and a partnership with Sainsburys to use their food waste as feedstock, the team of four graduates from Cambridge University are improving the process to get costs down enough to be viable in the market.
