It's no secret that supermarkets waste a whole lot of food in their day to day operations. When dealing with that sheer volume of food, how could they not? Still, grocery stores are beginning to realize this is a problem and have come up with some novel solutions. Here is another one, brought to you by UK supermarket Sainsbury's.

The popular chain has teamed up with waste management company Biffa to power their supermarkets using the food waste that would otherwise just head to the trash. The food waste, thanks to Biffa, is transformed into biogas and then that gas is used to power the stores. The process has been a success and, as of this writing, the company no longer sends any waste to landfill.

They are the first business to go all in on biogas for their power consumption needs and, hopefully, this is a trend that continues to catch on.
