All compostable products are biodegradable, but not all biodegradable products are compostable. The important differences between compostable and biodegradable products. Compostable products are those that can break down into organic matter, which provides a nutrient-rich soil conditioner. They are designed to break down faster than biodegradable materials, usually within 90 to 180 days, and without releasing any toxic residues. Compostable materials are often made from renewable resources such as plants and are commonly used for food packaging, utensils, and other disposable items. Compostable products have undergone strict testing to ensure that they break down within a specific time frame and do not release anything harmful into the environment. On the other hand, biodegradable products are those that can break down over time, but they may not necessarily break down into organic matter. They can take months or even years to completely decompose, and they can release toxic residues as they break down. Biodegradable materials are often made from petroleum-based materials, and they are commonly used for items such as plastics, which may not be suitable for composting. In summary, compostable materials are those that can break down into organic matter and provide nutrients to the soil, while biodegradable materials may not necessarily break down into organic matter and can release toxic residues. It is important to choose the right products based on their environmental impact.
