Recycling Nature: The Science of Composting
By Ella Coley, C2ST Intern, Waubonsee Community College
The United States throws away nearly 60 million tons of food each year. We produce more food waste than any other country in the world, equaling 325 pounds of garbage per person. It’s like everyone in America throws 6 and a half large packed suitcases directly into a landfill. According to the United States Environmental Protection Agency, when food and other organic materials break down and decompose in an environment that lacks a flow of oxygen, the bacteria that break down the food begin to emit greenhouse gases such as methane, carbon dioxide, and chlorofluorocarbons, all of which contribute to global warming. Wasted food in landfills across the United States emits greenhouse gases equivalent to the emissions from 37 million cars, according to the World Wildlife Federation. One solution that can help reduce the amount of food waste sent to landfills and reduce greenhouse gas emissions is composting.
