New Biotechnological Routes for Greener Bio-plastics from Seaweeds

In 19th century plastic was chemically invented. Usage of plastics was gradually increased in the 20th century. The wide range of its application is due to its versatile property. Plastic causes harmful effects on environment, human being, plants and animals. Annually more than 12.7million tons of plastic enter our ocean. To minimize the harmful effects of plastics biodegradable plastics are produced. Biodegradable plastics are synthesized by renewable sources. Seaweeds are used as a source for the production of bioplastics due to its high biomass and its growing ability in a wide range of environment. Polysaccharide is the important component for the making of bioplastics from seaweeds. These types of bioplastics are durable, less brittle and more resistant to microwave radiation. This review describes the role of seaweeds in the production of bioplastics.
