Evaluating Sustainable Nanomaterial Synthesis from Renewable Resources

Nanomaterial synthesis from sustainable resources presents a sustainable alternative to conventional processes based on non-renewable feedstocks and poisonous reagents. Opportunities, challenges, and directions in sustainable nanomaterial synthesis through bio-based resources are the topic of the chapter. Some recent developments show promise for agricultural wastes, natural chemicals, and renewable polymers in synthesizing various nanomaterials such as nanoparticles, nanocomposites, and nanostructured films. Bio-based nanomaterials, in a 2024 report, demonstrated a decrease of 35% in energy use relative to traditional synthesis and therefore have the potential to achieve vast environmental advantages. Additionally, renewable raw materials such as cellulose and starch-based raw materials demonstrated a decrease in the carbon footprint of nanomaterial production by up to 40% relative to traditional petrochemical processes. Scalability remains a major concern because current bio-based synthesis methods produce only about 10% of the world’s total nanomaterials. Scopes for scaling nanomaterial synthesis sustainably are vast, and new approaches like green catalysts, bioinspired templates, and solvent-free processes are likely strategies. In the coming decade, the industry of green nanomaterials will expand by 12% every year, which is a sign of a rosy future for green nanotechnology.
