Composting Basics
In 4 easy stages
Definition and Basic Principles:
Composting is the natural process of organic matter (such as food scraps, compostable food service products, and yard waste) breaking down into nutrient-rich material that can enrich soil and plants. This process occurs when materials decompose and transform into a dark, soil-like substance known as compost. Composting uses microorganisms, oxygen, and moisture to transform waste into something beneficial for the environment.

Over 60% of municipal solid waste is compostable!
Composting diverts waste sent to landfills, reducing methane emissions. If everyone in the U.S. composted, it would be the equivalent of removing the greenhouse gas emissions from over 7 million cars.
Benefits of Composting
Saves Water
Composting diverts waste sent to landfills, reducing methane emissions. If everyone in the U.S. composted, it would be the equivalent of removing the greenhouse gas emissions from over 7 million cars.
Supports Plant Growth
Compost provides plants with nutrients that are essential for growth. It also introduces beneficial microbes to the soil, which help create a healthier environment for plants to thrive.
Earth & Budget Friendly
Reduces the need for chemical fertilizers and soil conditioners.
Improves Soil Structure
Adding compost to soil improves structure, reduces erosion, and nutrient loss.

Choose Your Composting Style:
Decide between outdoor composting (such as a backyard pile) or indoor composting (like a kitchen bin). Indoor options are ideal for those with limited space.
Pick the Right Bin:
Select a bin that suits your space and composting style. For outdoor composting, look for a large, ventilated bin. For indoor composting, consider smaller, enclosed bins that help control odor.
Gather Your Materials:
Compost needs a mix of “greens” (like vegetable scraps) and “browns” (such as dried leaves or paper). This mix helps balance moisture and nutrients.
Start Adding Scraps:
Begin with small pieces of food scraps, and yard waste. Turn your compost every few weeks to keep it healthy, and help it break down faster.
Use Your Compost:
Once your compost looks dark, and crumbly, it’s ready to be added to your garden soil or potted plants!

*Some of these compostable items will be suitable for industrial and home, some only one or the other. For any certifiable items, look for the BPI and/or TUV logos to determine where they can be disposed of. For industrially compostable items, check with your local composting program or facility for specific guidelines on what’s accepted.

Home Composting Tips & Tricks
Insulate your bin
Adjust for weather and temperature changes by insulating your bin with straw, leaves, or a tarp to keep it active longer. You may continue to add materials to your pile.
Turn Regularly
Compost breaks down faster in warm weather, so keep turning your pile regularly! Always cover your fresh scraps with a layer of browns to keep pests away.
Add Browns
Compost piles don’t need to smell bad. Odors often mean too much moisture or greens. Fix it by adding browns and turning the pile.
Mix it up
Mixing your pile every one to two weeks helps speed up decomposition.

Industrial Composting Tips & Tricks
Remove stickers
Produce stickers are usually made of plastic, which is not biodegradable and can contaminate compost with microplastics. These microplastics can then contaminate the soil where the compost is used. Stickers are small, thin, and pliable, so they can get through screens designed to catch them. Once in the compost, they are difficult to remove and end up in the finished compost.
Educate others
Get your household on-board! Educate others about the importance of composting, and print out The Matter Composting Quick Guide. Before you know it, composting will become a routine part of your household waste management.
Bin in the bathroom
Keep an organics collection bin in your bathroom. Then you can easily compost tissues (without makeup, medicine or other solutions), cotton swabs (non-plastic), nail clippings and hair.
