This keynote explores cutting-edge sustainable synthetic strategies using benign alternatives to conventional chemical processes. Dr. Rajender Varma highlights the use of alternative activation energy inputs such as microwave, ultrasound, and mechanochemical methods in green media or solvent-free conditions. The synthesis of heterocycles, coupling reactions, and name reactions is discussed alongside the use of nanomaterials, often derived from waste as catalysts. The presentation emphasises a sustainable route to nanoparticle synthesis using winery waste polyphenols, with a focus on applications in catalysis, toxicity reduction, and environmental remediation, ultimately framing a circular economy through green nanochemistry.
