The increased global demand for plastic materials is increasing the production and consumption of plastic materials around the world. It has resulted in severe plastic waste pollution, which has affected both marine and terrestrial life. Microplastics can cause several health hazards. Plastics take a long time to decompose, and plastic recycling, incineration, chemical treatments, and landfills are not the optimum solutions for reducing plastic pollution. These characteristics lead to the search for ways to produce alternate biodegradable plastics that can decompose faster than conventional synthetic plastics. Microalgae are abundant in our ecosystems and can be collected, processed, and utilised to make biopolymers easily. Microalgae have no harmful effects but have a faster growth rate and the capacity to cultivate in wastewater. The polysaccharides in the algae can be used to produce biodegradable plastic. This …
