Compostable materials are organic substances that can break down naturally and enrich the soil. These materials include items like food scraps, yard waste, and certain types of paper. When composted, they decompose into nutrient-rich compost, which can be used to improve garden soil and support plant growth. Unlike regular trash, compostable materials help reduce landfill waste and promote a healthier environment. It's important to note that not all biodegradable items are compostable; for example, some plastics may break down but won't provide any benefits to the soil. By choosing compostable materials, we can contribute to a more sustainable future.
