In this RAZOR episode, we visit an experimental plant that can recycle any plastic and we investigate a new device that can give diet and lifestyle advice based on your genetic profile.

Emma Keeling is in Sweden, where Henrik Thunman and his team at Chalmers University have developed a process that can chemically recycle all kinds of plastic so that future production will not have to use more fossil fuels.

In London, Jo Colan meets DNA Nudge co-founders Chris Toumazou and Maria Karvela to find out more about the new device that's combining genetic testing with lifestyle monitoring, ushering in a new era of DNA-based personalized shopping to help people make smarter choices.
