If you piled up all the food that’s not eaten over the course of a year in the U.S., it would be enough to fill a skyscraper in Chicago about 44 times, according to an estimate from the U.S. Department of Agriculture.

And, when all this food rots in a landfill, it emits methane, a powerful greenhouse gas that contributes to climate change. In fact, a recent report from the United Nations from a panel of climate experts estimates that up to 10 percent of all human-made greenhouse gas emissions are linked to food waste.

So, here’s one solution to the problem: Dairy farmers in Massachusetts are using food waste to create electricity. They feed waste into anaerobic digesters, built and operated by Vanguard Renewables, which capture the methane emissions and make renewable energy.
