Biopolymers are a naturally occurring alternative to synthetic polymers that are linked by covalent bonds, which includes cellular components such as proteins, nucleotides, lipids, and polysaccharides. Based on the extensive literature review it was found that chitosan, lignin, and cellulose were predominantly used in the energy and environmental sectors. Due to their vast array of qualities, including the adsorption, flocculation, anticoagulation, and furthermore, have made them useful for treating wastewater and pollutant removal. Chitosan and lignin have been used as a proton exchange membrane in the energy storage device of fuel cells. As these biopolymers develop strong coordination connections with metal surfaces, they act as an anticorrosive agent, which inhibiting the corrosion. Besides, there are a lot of recent developments in the application of biopolymers for energy and environmental fields. The present review provides a concise summary of recent developments in membrane-based biopolymers role in energy and environmental field. In addition, this review is drawn to a conclusion with a discussion of future trends in the real application of biopolymers in a variety of different industries, as well as the financial significance of these future trends.
