Although biodegradable and degradable plastics have helped reduce plastic pollution, there are some drawbacks. Wooden disposable cutlery is available as a popular biodegradable alternative. Industrial uses include the production of drugs, biodegradable plastics, and chiral catalysts. Green composites are classified as a biocomposite combined by natural fibers with biodegradable resins. The use of biodegradable plastics has many advantages and disadvantages. Additionally, companies that label plastics with oxo-biodegradable additives as entirely biodegradable contribute to misinformation. There are vast examples and applications of biodegradable polymers. One of the most important and most studied groups of biodegradable polymers are polyesters. The structure of biodegradable polymers is instrumental in their properties. Under ASTM standards, polystyrene is regarded as not biodegradable. Flowerpots are now often also made from plastic, metal, wood, stone, or sometimes biodegradable material. Biogas captured from biodegradable green waste can be used as biofuel. Biodegradable plastic is the most prominent example. "Pseudomonas putida" is capable of converting styrene oil into the biodegradable plastic PHA. The cleansers are readily biodegradable and non-toxic to humans or aquatic life.
