Begin Your
Coffee
Ground Zero
Gather your used coffee grounds. Make sure they are cool and free of any leftover liquid to avoid mold.
Combine the coffee grounds with dry materials such as leaves, shredded paper, or cardboard.
Place the mixture in your compost bin or pile, layer with other organic waste to help it break down.
Keep it moist and turn occasionally to speed up decomposition and prevent odors.
Your compost is ready when it is dark, crumbly, and smells earthy.
