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.
I was always told to take all of the old coffee grounds, and any egg shells, and put them in the soil of plants or on the grass. The old wives' tale is that they make an free eggsellent (sorry for the pun,) fertilizer.
