We are going to give this one a yes, but it depends on what it’s made of. Most egg cartons are cardboard or recycled paper. However, there are still some styrofoam egg cartons around and some other materials to be careful of. You cannot add Styrofoam egg cartons to compost.
Like other forms of cardboard, egg cartons are a good addition to a compost pile. They add carbon and structure, improving aeration.
How To Compost Egg Cartons
Egg cartons are pretty easy.
You should only compost a clean egg carton. You don’t want food remains in it (or you’ll be adding mice to your compost too).
If the carton has any sort of stickers or plastic linings, you should remove these first.
You want to cut them up into small pieces. You can also soak them in water, making them easier to rip up. The water helps them break down and prevents them from soaking up the moisture in your compost. You especially want to do it if you are using a vermicomposting system.
These are great to layer with green materials. Remember to turn your compost periodically.
How Long do Egg Cartons Take to Break Down?
Egg cartons will typically break down in 2-4 weeks.
Can I Compost Egg Cartons
Yes, you can add egg cartons to compost, as long as they are paper or cardboard. You cannot add the styrofoam egg boxes.
