Written By Adeel Abbas

Green Chemistry Definition

Green chemistry, also known as sustainable chemistry, is the design and development of chemical products and processes that reduce or eliminate the use and generation of hazardous substances.

It is a discipline that seeks to reduce the environmental impact of chemical products and processes, while still meeting the needs of society.

The principles of green chemistry include the use of non-toxic and biodegradable materials, the use of renewable resources, the development of energy-efficient processes, and the design of products that can be easily recycled or safely disposed of.

Green chemistry has the potential to reduce pollution and environmental degradation, while also promoting economic growth and innovation. It can be applied to a wide range of industries, including pharmaceuticals, cosmetics, agriculture, and manufacturing.

Some examples of green chemistry include the development of biodegradable plastics, the use of renewable resources to create chemicals, and the use of chemical reactions to break down pollutants into less toxic components. Green chemistry has the potential to make a significant positive impact on the health of our planet and the well-being of people and communities.

Chemists are working towards developing a set of new, environmentally-friendly compounds which could replace hazardous chemicals. But this isn’t always easy. It can take decades to find replacements for common chemical ingredients like plasticizers, solvents, and polymers. So in the meantime, chemists have been using toxic alternatives which aren’t ideal.

History of Green Chemistry

If you have ever visited the modern home then I am sure you would come across the products of the chemical industry, one of them is cleaning products. Cleaning products are those things that will help us to clean and maintain the house. There are many types of cleaning products available on the market, but green cleaning products are widely preferred by people due to the reasons such as being less harmful to the environment.

Green cleaning products have been used since ancient times, but only recently the demand for the products has increased due to environmental issues. Green cleaning products are the products that will help us to minimize pollution and also use the eco-friendly approach.

If you are wondering how these products were invented then we have to wait for the old history and take a glimpse at ancient times.

Ancient History

Ancient history reveals that people were not aware of the problems caused by chemicals in our everyday life. It was the Egyptians who had introduced the first ever known technology of creating green cleaning products.

They used cotton balls soaked in lemon juice to clean their house and also to maintain their clothes. Even today people use this same technique to clean their homes. This is the first time in the history of mankind that people have created a cleaning product, but the fact remains that they are using the same technique for centuries.

Later, in ancient Greek era, the people started using soap and washing their clothes in rivers and ponds to get rid of the dirt.

In the Roman Empire, the people started using salt water to clean their homes and also to maintain their clothes. This is also the same technique that we follow in the present day to clean our homes.

This was the ancient era when people were very unaware of the importance of green chemistry. But it is said that it was Alexander the Great who brought a revolution in the field of green chemistry.

Alexander the great was the king of Macedonia, and he was one of the greatest military commanders and inventors of the world. He was the first person to introduce the concept of the use of green chemicals in the form of soap for washing clothes.

As per his research, he came across the fact that by mixing sodium bicarbonate with potassium hydroxide they got an alkaline solution that could clean the clothes and it also cleaned the water. He also noted that this solution remained a good antibacterial agent for the water and also could be reused for cleaning purposes.

Since people used this kind of cleaning solution to get rid of the bacteria, so the people called this solution soap.

This is the best part of ancient times when people used green chemistry for cleaning. The use of green chemicals in the form of soap has not only improved the quality of the water but also made the life of the people easier.

Green cleaning solutions are still being used in the present day, and it is because of the green chemistry that our lives are getting easier and easier.

Modern Era

The concept of green chemistry can be traced back to the late 1980s and early 1990s when scientists and policymakers began to recognize the negative environmental impacts of traditional chemical manufacturing processes. In response, a group of chemists, including John Warner and Paul Anastas, began to develop the principles of green chemistry as a way to reduce the environmental footprint of the chemical industry.

In 1998, Anastas and Warner published the “Twelve Principles of Green Chemistry,” which outlined the key principles of the discipline. These principles included the use of non-toxic and biodegradable materials, the use of renewable resources, the development of energy-efficient processes, and the design of products that can be easily recycled or safely disposed of.

Since the publication of the Twelve Principles, green chemistry has become a widely recognized field of study, with research and development efforts being carried out around the world. In addition, green chemistry has been embraced by a number of industries, including pharmaceuticals, cosmetics, agriculture, and manufacturing, as a way to reduce the environmental impact of their products and processes.

Today, green chemistry continues to evolve and grow as a discipline, with an increasing focus on sustainability and the development of new technologies and processes that minimize the environmental impact of the chemical industry.

Green chemistry Principle

There are 12 principles of green chemistry, which were first outlined by John Warner and Paul Anastas in 1998. These principles serve as a guide for designing and developing chemical products and processes that are environmentally friendly and sustainable. The 12 principles of green chemistry are as follows:

1. Prevention: It is better to prevent waste than to treat or clean it up after it has been created.
2. Atom Economy: Synthetic methods should be designed to maximize the incorporation of all materials used in the process into the final product.
3. Less Hazardous Chemical Syntheses: Wherever possible, synthetic methods should be designed to use and generate substances that are less toxic.
4. Designing Safer Chemicals: Chemical products should be designed to be fully effective, yet have little or no toxicity.
5. Safer Solvents and Auxiliaries: The use of auxiliary substances (e.g. solvents, separation agents, etc.) should be made unnecessary wherever possible and innocuous when used.
6. Design for Energy Efficiency: Energy requirements of chemical processes should be recognized for their environmental and economic impacts and should be minimized.
7. Use of Renewable Feedstocks: A raw material or feedstock should be renewable rather than depleting whenever technically and economically practical.
8. Reduce Derivatives: Unnecessary derivatization (use of blocking groups, protection/deprotection, temporary modification of physical/chemical processes) should be minimized or avoided if possible because such steps require additional reagents and can generate waste.
9. Catalysis: Catalytic reagents (as selective as possible) are superior to stoichiometric reagents.
10. Design for Degradation: Chemical products should be designed so that at the end of their function they break down into innocuous degradation products and do not persist in the environment.
11. Real-time Analysis for Pollution Prevention: Analytical methodologies need to be further developed to allow for real-time, in-process monitoring and control prior to the formation of hazardous substances.
12. Inherently Safer Chemistry for Accident Prevention: Substances and the form of a substance used in a chemical process should be chosen to minimize the potential for chemical accidents, including releases, explosions, and fires.
