Get ready to learn about composting on Learn About Composting Day on May 29! This special day has been celebrated since the early 2000s, and it's an excellent opportunity to educate yourself and others about this simple yet effective way of reducing household waste. Composting helps reduce emissions from landfills, create nutrient-rich soil for growing plants and vegetables, and can even save you money in the long run by reducing your need for store-bought fertilizer.

TIMELINE

Learn About Composting Day Timeline

Origins of the Holiday

Learn About Composting Day was established in the early 2000s to raise awareness about the benefits of composting.

Spread of the Practice

By 2011, about 5 million U.S. households composted at home, according to the Environmental Protection Agency (EPA).

Growing Impact

In 2015, composting in the U.S. helped to reduce carbon emissions equivalent to taking over 2 million cars off the road for a year.

Community Programs

By 2018, numerous city and county programs across the U.S. began providing compost bins and instruction, as well as pick up service for compostable material.

Rise of Composting Apps

In 2020, educational apps like ShareWaste saw a surge in usage, connecting people who wish to compost their scrap food with those who have a compost bin.

WHY THIS DAY MATTERS

Why Learn About Composting Day is Important

Create Nutrient Rich Soil

When organic material is broken down through decomposition, it produces soil that's rich in nutrients and beneficial microbes. This nutrient rich soil can then be used to create healthier plants, better yields and even tastier produce! Learning about composting gives us the knowledge we need to create this ideal environment for growing food.

Reduce Industrial Waste

Composting helps to reduce the amount of waste that is sent to landfills and incinerators, which can then be turned into fertilizer for plants. This not only reduces harmful emissions from these facilities but also offers a cost effective solution to dealing with food scraps and other organic materials.

Protect Our Environment

Composting prevents the release of methane gas, a potent greenhouse gas, from decaying organic matter in landfills. By composting instead of disposing organic waste in the garbage can, we can do our part to protect the planet and take meaningful steps towards reducing our carbon footprint.
