When something is compostable, it means it can disintegrate or break down into non-toxic, natural elements. Composting is the natural process of discarded items reverting back into natural elements.
When something composts, it becomes “humus,” which is the decomposition of dead plant matter. It is incredibly rich in nutrients, holds moisture, and is very valuable to new plants.
When people think of “compost” they often think of eggshells and vegetable scraps, but plenty of other materials and products can be compostable too.
