Nasa-funded project uses yeasts to turn plastics and other waste into edible proteins, fats and flavourings

Cookies produced from upcycled plastic may sound like something straight out of a dystopian sci-fi plot. But researchers say that they have succeeded in creating such a product as part of a Nasa-funded project aimed at feeding astronauts on future space missions.
