Nasa-funded project uses yeasts to recycle plastics and other waste into food shaped into biscuits by 3D printers 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.

The technology uses specially designed yeasts to transform plastics and agricultural waste into edible proteins, fats and flavourings.
