Green organic chemistry represents a modern approach aimed at designing chemical reactions and processes that minimize environmental impact and preserve natural resources. This philosophy emerged in response to environmental concerns caused by toxic solvents, hazardous chemical waste, and heavy reliance on fossil fuels in traditional chemical industries. Green organic chemistry is based on key principles such as waste prevention, the use of safer solvents, energy efficiency, and the selection of renewable feedstocks instead of non-renewable resources. It also focuses on developing high-yield reactions that reduce the formation of harmful by-products. Important applications include replacing toxic organic solvents with greener alternatives such as ethanol or water, as well as utilizing biocatalysis or organocatalysis to reduce dependence on heavy metals. Innovative techniques such as solvent-free reactions and microwave-assisted synthesis are also employed to decrease energy consumption and reaction time. This approach plays a crucial role in pharmaceutical manufacturing, petrochemical industries, and polymer production by lowering toxic emissions and improving operational safety. In the long term, green chemistry strategies contribute to cost reduction by minimizing raw material usage and energy demand. Although implementing green chemistry principles requires process redesign and investment in research and development, it represents one of the most promising future directions in organic chemistry due to its significant environmental and public health benefits.
