Does food waste decompose in landfill?

But wasted food isn’t just a social or humanitarian concern—it’s an environmental one. When we waste food, we also waste all the energy and water it takes to grow, harvest, transport, and package it. And if food goes to the landfill and rots, it produces methane—a greenhouse gas even more potent than carbon dioxide.
