Plastic pollution has become a pressing environmental issue, necessitating the development of innovative solutions to mitigate its adverse impacts. In this study, we investigate the potential of water hyacinth (Eichhornia crassipes) and seaweed as cellulose-based natural polymers for combating plastic pollution. Both water hyacinth and seaweed possess high cellulose content, rendering them promising candidates to produce sustainable alternatives to conventional plastics derived from fossil fuels. By utilizing these aquatic plants and transforming them into useful derivative products, such as bioplastics, we can reduce dependence on traditional plastics and thereby mitigate the environmental consequences of plastic waste. Furthermore, the utilization of water hyacinth and seaweed presents opportunities for a circular economy, promoting resource recycling and repurposing. Through an exploration of the environmental and economic aspects of plastic pollution, this study underscores the potential of water hyacinth and seaweed in effectively addressing plastic pollution and fostering a more sustainable future.
