What do you normally do with your leftover food? The Japanese don’t waste anything as they have recently developed a way to use leftover school lunches to create energy – approximately 200 kilograms of collected waste from half a dozen local schools are used to create biofuels, and the ethanol collected will then be used as a teaching aid for alcohol lamps while the methane has been targeted to generate electricity inside the experiment facility. While the amount of energy collected isn’t much, it is still better than letting it waste away.
