We drink over 2 billion cups of coffee every day, generating millions of tonnes of used coffee grounds each year. Left to decompose naturally, these grounds would give off 2.3 billion cubic metres of methane, the equivalent in terms of global warming to France's annual CO2 emissions. bio-bean has a solution to this growing problem. They collect used coffee grounds and convert them into a wide variety of products from solid fuels to flavourings, while developing innovative new applications from oils to dyes, proteins and bioplastics.

RE:TV Refining Solar
Oxford PV’s perovskite technology is made with abundantly available, low-cost synthetic materials. It is 200 times more effective at absorbing the sun’s energy compared to conventional silicon solar cells. For this reason, it can be applied as a thin film - less than one micron thick - to silicon...
