ABSTRACT

Green chemistry represents a transformative approach to chemicalresearch, focusing on minimizing environmental damage whileenhancing efficiency and safety in chemical processes. Sustainablesynthesis, a critical component of green chemistry, seeks to developinnovative methods that reduce reliance on toxic reagents and wastefulprocesses, contributing to environmental preservation. This reviewexplores the recent advancements in eco-friendly chemical processesand sustainable synthetic routes that address global environmentalchallenges such as pollution, resource depletion, and climate change.Key areas of progress include using alternative solvents like water,ionic liquids, and supercritical fluids, which replace conventional toxicorganic solvents, significantly reducing hazardous waste. Theapplication of renewable feedstocks derived from biomass has alsogained traction, offering a sustainable alternative to fossil fuel-basedchemicals. The growing use of biocatalysis-employing enzymes orwhole cells has enhanced selectivity and efficiency in chemicalreactions while operating under milder, less energy-intensive conditions. Catalysis,particularly heterogeneous catalysis, has shown remarkable potential in improving atomeconomy and enabling cleaner, more sustainable reactions. Energy-efficient methods such asmicrowave-assisted synthesis, ultrasound, and photochemical reactions further reducechemical processes' energy footprint. These advancements are being integrated into various industries, including pharmaceuticals, agriculture, and materials science, paving the way forlarge-scale applications of green chemistry principles. Despite these promising developments,challenges remain in scaling up these processes and integrating them into existing industrialframeworks. Future research aims to overcome these barriers, fostering innovation insustainable synthesis. This review highlights the potential of green chemistry to revolutionizethe chemical industry by promoting eco-friendly practices, reducing environmental impact,and ensuring a more sustainable future.
