More food reaches landfills and incinerators than any other single material in municipal solid waste (MSW). In 2011 alone, more than 36 million tons of food waste was generated, with only four percent diverted from landfills and incinerators for composting. The best way to low this high amount of waste? Reduce your own food waste by buying less, and eating leftovers! Composting won't hurt either.
