What are the example of biodegrable?

Biodegradable materials include natural substances like food waste, paper, and cotton, which can decompose through the action of microorganisms. Other examples are biodegradable plastics, such as polylactic acid (PLA) and polyhydroxyalkanoates (PHA), designed to break down more quickly than traditional plastics. Additionally, compostable items, such as certain packaging and utensils made from plant-based materials, are also considered biodegradable.
