This is the first post in my #FutureGadgets series, this one is very surprising. Coffee is a staple for millions of people across the world, particularly in recent years with the rise of coffee shops - but what happens to the waste from the coffee making process? The answer is, it's currently just waste - but entrepreneurs worldwide are trying to find a use for it. A US entrepreneur thinks he's found the solution. The idea is, that with processing you could turn about 85% of the energy wasted into bio fuels for heating buildings or powering transport which could make a huge difference to the progress of global warming. Although it might not seem like it, we're talking a HUGE amount of energy, London's coffee industry could create around 200,000 tonnes of waste every year, the same amount produced by the UK's biggest supermarkets.
