Astonishingly, 40% of our total waste comes from the food we throw out. Composting is nature’s way of recycling that leftover food. Leftover food scraps, leaves, and yard trimmings can easily be broken down into rich, nutritious soil (called humus) through the composting process. This humus can help enrich your school’s garden and landscape by adding nutrients and retaining moisture in soil, thereby reducing the need for water. Likewise, composting helps to reduce the amount of waste that goes into our landfills.
