What is National Learn About Composting Day?

National Learn About Composting Day is celebrated every year on May 29 in the United States. The day encourages people to explore composting;a natural method for recycling food scraps, yard waste, and other organic material into rich, fertile soil.

It’s a simple way to reduce waste, support local ecosystems, and improve your garden. Composting helps close the loop in nature, turning leftovers into life.

History and Origin

National Learn About Composting Day was created in 2011 by Bob Matthews, a gardener from Rochester, New York. His goal was to promote composting as a practical step toward a greener lifestyle. He introduced the day as part of a larger push for environmentally friendly living.

Since then, the day has gained support from environmental groups, schools, and community gardens. The focus is not just on making compost but on learning how it works and why it matters. From kitchen bins to large-scale operations, composting has become an everyday act of climate action.
