When something is labeled at compostable, it means that the product “can” be turned into compost as long as it's under the correct conditions.
Compostable means that a product will break down into natural elements, but only in a compost setting. Compostable materials are typically made from plants and other organic materials, such as corn starch, bagasse, or PLA plastic. Compostable products have two added benefits over biodegradable options: they break down much faster, many in roughly 90 days, and they also break down into nutrient-rich products, which generates healthy soil for the planet.
