Get the Scoop on How Composting Helps Our Environment

1. Gather Materials
Choose nitrogen-rich and carbon-rich materials like fresh grass clippings, fruit, vegetable scraps, coffee grounds, dry leaves, twigs, and wood chips. Materials like this provide the necessary ingredients for microorganisms to decompose organic matter efficiently. Green offers the energy source (nitrogen), while browns provide structural support and carbon, helping the pile speed up the composting process!

2. Find the Right Place for Your Compost Pile:
Choosing a spot to start your compost is very important. Look for a spot that’s not prone to waterlogging and that receives partial shade— this ensures that your compost maintains ideal temperature and moisture levels for microbial activity. If your compost is placed directly in the sun, it may dry out quickly and will need supplemental watering.

3. Prepare Your Compost Ingredients
Before adding your ingredients to the compost pile, be sure to break and chop them up into smaller pieces. Doing this helps other materials in the pile break down faster!

4. Building Your Compost Pile
When starting your pile, you want to create a four- to six-inch layer of twigs and wood chips. This layer is important for creating air-flow and absorbing liquids. Next, add your green ingredients (fresh grass clippings, vegetable scraps, dry leaves, etc.). Be sure to cover your food scraps with four to eight inches of dry leaves or other browns, this helps to ensure air circulation throughout your compost! Always ensure your compost pile has enough water, it should have the same amount of moisture that a wrung-out sponge would have.

Did you know our Education Outreach Center features a composting station? In addition to exploring the many wonders of science, visitors can get hands-on with composting—
discover how it works, learn how to start your own, and see nutrient-rich finished compost up close! Learn more by booking your free Self Guided Tour on our website.

Here at the EOC, we use a method called “cold composting”—a slower, but much less labor-intensive way to turn organic waste into nutrient-rich compost. Cold composting allows nature to do its thing—no frequent turning or constant moisture needed! We are always encouraging composting here at the EOC, after school field trips we’ll throw our food waste in our compost bin to use in our garden later.
