Biodegradable materials are materials that can break down naturally over time. These materials are found in substances such as food waste, paper, and some natural products. They are broken down by living organisms like bacteria and fungi. The process happens in environments such as soil and water.

Biodegradable materials are found in natural environments around the world. They can take different amounts of time to break down, depending on the material. Some products are designed to be biodegradable.

Biodegradable materials are common in both natural and human-made items. They are part of how materials change over time in the environment. These materials exist in many ecosystems and everyday uses.
