Free report: green chemistry — our future

by Nikolay Dagaev | 20-04-2020 01:43 recommendations 0

Good health and safety to all! In my report on a free topic, I want to talk about the technology of the future — green chemistry.
The very word "chemistry" is still something negative in the minds of consumers. At least in Russia, the phrase - " this is chemistry!» it means something toxic and harmful to your health.

Green chemistry is a fundamentally new approach to solving environmental problems, using clean and less polluting industrial processes and ensuring that manufacturers take responsibility for their products. [1]

It is Green chemistry that is the long-term lever of environmental management, contributes to public health and helps preserve the environment for future generations.

The goal of green chemistry is to prevent contamination during the creation of chemical products or processes, i.e. to prevent contamination at the very early stages of planning and implementing chemical processes.
In 1998, P. Anastas and J. Warner in the book "Green chemistry: Theory and practice" [
2] formulated 12 principles of Green chemistry. These principles reflect the work of the scientific community, industry, and government agencies to reduce or eliminate the use of hazardous materials and chemical processes.

1. It is better to prevent loss than to treat or clean up waste.

2. Synthesis Methods should be chosen in such a way that all the materials used in the process are maximally translated into the final product.
3.
Synthesis Methods should be chosen so that the substances used and synthesized are as little harmful to humans and the environment as possible.

4. Creating new chemical products, we must try to maintain the efficiency achieved earlier, while reducing the toxicity.

5. Auxiliary substances in production, such as solvents or separating agents, should not be used at all, and if this is not possible, their use should be harmless.

6. Be sure to take into account energy costs and their impact on the environment and the cost of the product. If possible, the synthesis should be carried out at a temperature close to the ambient temperature and at atmospheric pressure.

7. Raw materials and consumable materials must be renewable in all cases where it is technically and economically profitable.

8. Where possible, avoid getting intermediate products (blocking groups, joining and removing protection, etc.).

9. Always give preference to catalytic processes (if possible, the most selective).

10. Chemical products should be designed so that after its use he did not persist in the environment and break down into innocuous degradation products.
11. We need to develop analytical methods to monitor in real time the formation of hazardous products.

12. The substances and forms of substances used in chemical processes should be selected in such a way that the risk of chemical hazards, including leaks, explosion and fire, is minimal [2].

    Hi Nikolay Dagaev, this is a mentor Sang Su Lee.

    Many people perceive chemical products negatively. However, there is no single substance that is not made of chemical compounds in the world! I can guarantee. I am so glad that green chemistry is trying to change this somewhat unfair perception toward the word chemistry and is caring each and every process in production to prevent loss of environmental health.

    Thank you for your report!

    Hello Nikolay Dagaev, this is mentor Taehyun!

    Thank you for the report about the principles of green chemistry! The principle looks really practical for chemical engineers who are trying to protect the environment. I think to solve the problems related to chemical products, we, the consumers have to try hard to filter the product which is not good for the environment, but also the attention of the chemical engineer is essential! So, your principles look really effective for environmental protection!

    Thank you for the good report!

    Green cheers!
