Compost is organic material that can be added to soil to help plants grow. Food scraps and yard waste together currently make up about 30 percent of what we throw away, and should be composted instead. Making compost keeps these materials out of landfills where they take up space and release methane, a potent greenhouse gas.
When food waste goes to landfills, it cannot decay efficiently and produces methane, a greenhouse gas. Composting these organic materials that have been diverted from landfills reduces the emission of methane into the environment. The large amount of methane gas in our atmosphere is a known contributor to global warming.
