Which egg carton is better styrofoam or cardboard?

Cardboard egg cartons are better than Styrofoam egg cartons because they are more environmentally friendly. Styrofoam is a type of plastic that is not biodegradable, meaning it can take hundreds of years to break down. Cardboard, on the other hand, is a biodegradable material that can be broken down by bacteria and fungi in a matter of weeks or months. Additionally, cardboard egg cartons are recyclable, while Styrofoam egg cartons are not.
