Plastics are a necessity that are usually made from non-renewable resources. Because synthetic plastics cannot biodegrade, their widespread manufacture and indiscriminate usage represent a severe danger to the environment and cause issues. Daily use of various plastics should be reduced, and their place should be taken by biodegradable alternatives. Biodegradable and environmentally friendly polymers are essential for addressing sustainability concerns or environmental problems brought on by the manufacture and disposal of synthetic plastics. Marine industries produce about 2–5 billion tonnes of waste annually, which negatively affects the environment. These polymers' superior mechanical characteristics, biostability, and biodegradability make them more palatable and environmentally benign than conventional plastics. The amount of waste produced is greatly decreased when synthetic plastic packaging is replaced with biodegradable polymers made from animal byproducts. The usage of waste biomass for bioplastics production, their structure, mechanical properties, and demand in industrial areas like biomedical, food packaging, 3D printing, 4D printing, cancer detection, drug Carriers, and application for post-surgical ulcers are some of the key points highlighted in this review.
