Cellulose-Based Materials as a Sustainable Alternative to Plastics: Mitigating Environmental Pollution Through Biodegradability and Reduced Toxicity

This review examines the potential of using cellulose materials for overcoming environmental issues such as pollution, microplastics, and ecological toxicity as sustainable alternatives to petroleum-based plastics. Unlike plastics, which persist in the environment and break down into microplastics, cellulose materials readily degrade into non-toxic organic compounds, thus reducing pollutants in soil and water. The review outlines the relatively low environmental impact of cellulose production from renewable materials such as timber, agricultural waste, and non-timber flora. Cellulose, unlike petroleum-based polymers, is produced with lower energy inputs, greenhouse gas emissions, and greater carbon capture during plant growth. Sustainably harvested and farmed cellulose strengthens its circular economy relationship, clocking in with boastful compostability, and in some instances, recyclability. The described processes, including the manufacture of nanocellulose, chemically and mechanically treat the cellulose, improving its strength, flexibility, moisture resistance, and expanding its application in packaging, biocomposites, textiles, and medical devices. There are still some disadvantages, such as high costs, lack of industrial composting, and absence of enabling legislation. The review calls for greater advocacy of policy change, technological improvements, and public awareness campaigns aimed at promoting the use of cellulose. Most importantly, it demonstrates why these materials are needed to reduce pollution inflicted by plastics, protect biodiversity, enhance sustainability, and manage waste through responsible consumption.
