Keep your kitchen scraps from fruits, vegetables, and coffee grounds in a composting bin or container. Try adding them to your garden or starting a compost site in the yard. You'll grow a better garden, create deeper topsoil, recycle nutrients, and save landfill space. If, over the course of a year, everyone in the US composted their kitchen scraps instead of sending them away with the trash, the organic waste diverted from landfills could make a three-foot-high compost pile to cover the city of San Francisco.
