H2 What is Green Chemistry?

H3 An Introduction

Green chemistry is a cutting-edge field of science that seeks to transform the way we produce and utilize chemicals. By focusing on sustainability and environmental responsibility, green chemistry aims to minimize or eliminate the harmful effects of chemical processes on human health and the planet. Embracing a holistic perspective, green chemistry encompasses all aspects of chemical development, from design to disposal.

H3 Principles of Green Chemistry

The practice of green chemistry is guided by 12 principles, developed by Paul Anastas and John Warner in the 1990s. These principles provide a framework for scientists and researchers to design and implement environmentally friendly chemical processes and products:

1. Prevention: It is better to prevent waste than to treat or clean it up.

2. Atom Economy: Synthetic methods should maximize the incorporation of all materials used in the process into the final product.

3. Less Hazardous Chemical Syntheses: Designing chemical processes to use and generate substances that possess less or no toxicity to human health and the environment.

4. Designing Safer Chemicals: Designing chemical products that are effective while minimizing their toxicity.

5. Safer Solvents and Auxiliaries: Utilizing solvents and other auxiliaries that are less hazardous and minimize environmental impact.

6. Energy Efficiency: Designing chemical processes that require less energy.

7. Renewable Feedstocks: Using renewable or sustainable feedstocks for chemical production.

8. Reduce Derivatives: Avoiding the unnecessary generation of derivatives in synthesis.

9. Catalysis: Employing catalytic processes whenever possible to minimize waste and energy consumption.

10. Degradable Chemical Products: Designing chemical products that can break down into benign substances after use.

11. Real-time Analysis for Pollution Prevention: Implementing real-time monitoring and control systems to minimize or eliminate pollution.

12. Inherently Safer Chemistry for Accident Prevention: Designing chemical processes and products that minimize the potential for accidents and hazards.
