"Compostable" refers to materials that can break down naturally into organic matter, enriching the soil without harming the environment. These materials typically include food scraps, yard waste, and certain biodegradable products. When composted, they decompose through the action of microorganisms, resulting in nutrient-rich compost that can be used to improve soil health. Unlike regular trash, compostable items are designed to decompose in a composting environment, which can be a backyard pile or an industrial facility. This process helps reduce landfill waste and greenhouse gas emissions, contributing to a more sustainable ecosystem. Examples of compostable items include fruit peels, coffee grounds, and paper products.
