India, second largest producer of pesticides and ranked 12th in pharmaceutical production, is fast emerging among the top 5 players in selected petrochemicals. These facts, in turn, have led to an increased stress on our delicate environmental balance, thus India needs to pursue green chemistry along with progressive chemistry more exhaustively and extensively. Due to large-scale production of pesticides, pharmaceuticals, petrochemicals, and other consumer durables, there is a great potential for green chemistry research in India to refine the existing technologies and also to find more environmentally benign alternatives. Currently, green chemistry research in India is confined mainly to areas of greener synthetic strategies, catalyst development, usage of biocatalysis, usage of nonconventional technologies, and analytical techniques. In developing green synthetic strategies, Indian scientists are mainly concentrating on avoiding environmentally noncompatible reagents, solid-phase syntheses, modification of synthetic routes to decrease the number of steps and increase overall yield, usage of newer catalysts and simplification of classical procedures of reaction. However, what is required is a combined approach for a greener synthesis.

In India, though the concept of green buildings has been around for almost a decade, it is gaining momentum now with more developers showing interest in offering eco-friendly options in residential as well as commercial segments. The construction industry in India is adopting green building solutions and the Indian government has been proactive in making green designs for buildings mandatory in many areas. Please check the website of GRIHA (Green Rating for Integrated Habitat Assessment) and check the details about upcoming net zero campus of the Nalanda University. Since it is the endeavour of the University to develop a sustainable campus which will have a net zero or near zero environmental impact, the first of its kind in the world; special attention was paid to the manner in which each of the schemes addressed the issues of sustainability

Dear Prof. Parisa

Innovative research on the development of alternative sustainable technologies.

Dear Dr. Parisa,

Green chemistry, also known as sustainable chemistry or ecological chemistry, provides for the implementation of principles to reduce and eliminate the use or generation of substances harmful to the environment, by new chemical processes and "clean" ways of synthesis. that is to say, respectful of the environment: from now on, the development of industrial chemistry, derived from hydrocarbon derivatives according to a paradigm inherited from the twentieth century, must integrate the objectives that environmental governance has identified in its economic and social aspects. preservation of human health (growing pathologies1: Alzheimer's disease, cancer, diabetes). One of these issues is to curb the massive production of carcinogenic neurotoxicants such as bisphenol A, phosgene (polycarbonates and polyurethanes), endocrine disruptors and substances classified CMR from petrochemicals. There is also a green alternative chemistry in France for fuels and engines developed by the company SOCCAR France, registered with the French Agency for Sanitary Security (ANSES).

Therefore, we are for the following suggestions:

- encourage the design of products and chemical processes that reduce the use and production of hazardous substances.

- reduce and avoid pollution from its source.

- take care of pollution in an original and innovative way.

- take green chemistry seriously because it aims to avoid environmental problems, due to the release of dangerous substances, even before they happen.

Application of the principles of green chemistry;

-prevention: it is better to produce less waste than to invest in sanitation or waste disposal;

Atomic economy: the syntheses must be designed with the aim of maximizing the incorporation of the materials used during the process into the final product;

where possible, synthetic methods should be designed to use and create substances that are low or non-toxic to humans and have no environmental impact;

-the chemicals must be designed to fulfill their primary function while minimizing their toxicity;

-where possible, the use of auxiliary substances (solvents, separating agents, etc.) or the use of harmless substances should be abolished. Unconventional methods of activation may be used: use of water as a solvent, supercritical fluids, microwave heating, replacement with ionic liquids, etc. ;

-the energy needs of chemical processes have economic and environmental implications that must be taken into account and minimized. Synthetic methods must be developed under ambient temperature and pressure conditions;

- where technology and financial means permit, the raw materials used must be renewable rather than non-renewable;

-where possible, any unnecessary deviation from the synthesis scheme (use of blocking agents, protection / deprotection, temporary modification of the physical / chemical process) must be reduced or eliminated;

catalytic reagents are more effective than stoichiometric reagents. The most selective catalytic reagents should be favored;

-the chemicals must be designed so that they can dissociate into non-harmful degradation products at the end of their useful life, in order to avoid their persistence in the environment;

-analytical methodologies must be developed to enable real-time and in-process monitoring and control before hazardous substances occur;

-the substances and form of the substances used in a chemical process should be chosen to minimize the risk of chemical accidents, including releases, explosions and fires.

with my best wishes

To keep environment safe and secure we follow few instructions that make sense in improving ecological environment.

For that we sincerely apply few principles to reduce increase in substances that harmful to Greenery and their aspects

I suggest that GREEN CHEMISTRY should be the optimum substitute of CHEMICAL TREATMENT STRATEGIES in the environment. We must apply SUSTAINABILITY to protect our environment and to reach economical resources also, without the control of Monopolistic Companies. Regards

Green chemistry is the design of chemical products and processes that reduce or eliminate the use and generation of hazardous substances throughout their lifecycles: design; manufacture; use; and end of life.

Green chemistry builds on conventional chemistry and engineering by applying 12 fundamental principles that guide the molecular design of sustainable chemical products and processes. Adhering to these principles prevents pollution and waste, leads to synthesis of chemicals in less hazardous and more efficient ways, promotes the use of renewable feedstocks and leads to the design of safer chemicals.

https://www.greenbiz.com/article/5-strategies-accelerate-green-chemistry

Designing chemical processes and products so as to reduce or eliminate the use and generation of hazardous substances throughout their lifecycles is overall aim of Green Chemistry. As approximately 90% of manufactured goods are in some way linked to the chemical industry. Therefore strict adherence of green (ecofriendly) approaches at designing, manufacturing, use, and disposal is the essential part of green chemistry.

• Designing of sustainable chemical products and processes
• Compliance of environmental norms to prevents pollution and waste
• Synthesis of chemicals in less hazardous and more efficient ways
• Use of renewable feedstocks and leads to the design of safer chemicals
• Sensible and responsible research, development and business involving all concerned at various levels.

Green projects are a very good idea because we have to think not only today but also for future generations. The bad thing is that sometimes good ideas lie in bad thoughts and backstage thin accounts.

I do not agree with the merger because green chemistry must have a curriculum related to this science only so that the details can be studied with high accuracy.

Green Chemistry encourages thinking out of the box and implement novel ideas in a ways to replace hazardous and eco-unfriendly materials that have been used in a particular chemical process for decades. Such breakthroughs are paving the way to creativity and resourcefulness in chemistry. Applying the concepts of Green Chemistry reduce use of unnecessary chemicals, fewer synthetic steps, lesser amount of waste and end of the pipe treatment, allow for higher yields, faster manufacturing and increased capacity, resulting in lower costs and higher profits.
