INTRODUCTION
Green chemistry, defined as the development of chemical products and processes that reduce or eliminate the use and production of hazardous substances, represents a transformative approach to sustainability.
Emerging in the early 1990s with the Pollution Prevention Act and the 12 principles established by Paul Anastas and John Warner, green chemistry integrates ecological considerations into the core of chemical research and industry.
In order to lower the hazards to the environment and public health, green chemistry uses renewable feedstocks, energy efficiency, waste control, and atom economy.
The impact of this sector has spread to a number of industries, including consumer goods, energy, agriculture, and pharmaceuticals.
By reducing manufacturing costs and increasing process efficiency, green chemistry not only reduces the environmental impact of chemical processes but also opens up new business prospects.
Green chemistry combines tools and procedures that enable chemical engineers' study into the synthesis of chemical compounds and methods to limit or eliminate the usage of harmful chemicals in order to create more G.

environmentally friendly, efficient products with less waste.
It will now have a significant impact on the fertilizer and chemical industries .
Aim of AuGreen ChemistryAy to make prolonged molecular existence.
Given this goal, it is hardly surprising that it has been used in a variety of business sectors.
Green chemistry is the part of environmental chemistry synthesis that have ecological approaches and it involves decreasing or eliminating the use of hazardous and toxic substances to make hazardous chemical compounds.
Establishment of molecular sustainability is the main ambition of green chemistry method.
It is hardly unexpected that it has been used in various industrial areas given this objective from agriculture to the fields of aircraft, automobiles, cosmetics, electronics, energy, home goods, and pharmaceuticals .
As a result, green chemistry provides risk-free production of a variety of compounds.
It is very difficult for industries and research to develop non-hazardous products under green chemistry.
A novel approach to produce, process, and using chemicals called "green chemistry" goal to decrease the chances to danger for both human health and the ecosystem, such as .
o The Environmentally Benign Chemistry o The clean Chemistry o The Atom Economy What is Green chemistry? Green or Sustainable Chemistry is a term that refers to the creation of chemical products and processes that reduce or eliminate the use and production of harmful substances.
The practice of chemistry in a manner that maximizes its benefits while eliminating or at least greatly reducing its adverse impacts has come to be known as green chemistry.
As a new branch of chemistry with ecological approaches it involves reducing or eliminating the use of harmful substances in chemical processes as well as reducing harmful and toxic intermediates and products.
To be called "green," each reaction should have three green components: solvent, reagent /catalyst and energy Another aspect of the definition of Green Chemistry is found in the phrase Auuse and generationAy.
Basic Principles of Green Chemistry The processes of green chemistry developed to date primarily cover all areas of chemistry, including organic, inorganic, biochemical, polymeric, toxicological, environmental, physical, and technological, among Green chemistry is founded on twelve principles that can be used to create or recreate molecules, materials, reactions, and processes that are safer for human health and the environment.
Green chemistry is a Hippocratic oath for chemists, and a new generation of scientists and technologists is emerging that economically examines the materials and processes utilized in development and production in order to protect the environment and natural There is no risk if no hazardous materials are utilized or produced, hence there is no need to be concerned about eliminating hazardous materials from the environment or restricting exposure.
Green chemistry is a Hippocratic oath for chemists, and a new generation of scientists and technologists is emerging that economically examines the materials and processes utilized in development and production to protect the environment and natural resources.
"Green chemistry is about reducing waste, raw materials, risks, energy, environmental impact, and cost.
" If no hazardous compounds are utilized or created, there is no risk and no need to concern about removing them from the environment or restricting exposure to them.
Principles of green chemistry are Waste Prevention (G-.
: Try to develop such conditions in the process that produces very less waste .
ide produc.
Atom Economy (G-.
: A synthetic approach used to be designed to increase the formation of all input substance into finished output.
Therefore, such synthetic techniques should be used to transform as many reactant atoms as possible into manufactured goods.
Safe Chemical Synthesis (G-.
: This synthetic approach should be planned to utilize and industrialized substances that have low toxicity impact to human being and animal as well as environment.
Designing Safer Chemicals (G-.
: It is necessary to develop chemical compounds that affect their essential functions while reducing and eliminating their toxicity.
Safer Solvents and Auxiliaries (G-.
: In processes, auxiliary substances like solvents and partition agents should be avoided.
however, if they are used, they should be nontoxic materials.
In processes, auxiliary substances like solvents and separation agents should be escape.
however, if it is used, it should be nontoxic materials.
Design for Energy Efficiency (G-.
: In light of the detrimental effects that chemical processes have on the economy and the environment, their energy requirements should be reduced.
The best place to carry out synthetic operations is at atmospheric temperature and pressure.
Use of Renewable Feed stocks (G-.
: When scientifically and financially achievable, a raw material or feedstock should be renewable rather than finite.

Reduce Derivatives (G-.
: Use of blocking groups, protection and temporary modification of physical or chemical processes are undesirable derivatives that should be minimized or avoided whenever possible because they call for additional reagents.
Catalysis (G-.
: Catalytic chemicals should be of better-quality to stoichiometric reagents.
hich are as selective as feasibl.
Design for Degradation (G-.
: The chemical compounds should be produced in such a way that they decompose into harmless elements at the end of their use and do not remain in the environment for long.
Pollution Prevention Real-Time Analysis (G-.
: Analytical methodologies must be further improved to allow real time while during production monitoring and control before to the production of potentially dangerous Inherently Safer Chemistry for Accident Prevention (G-.
: To lessen the possibility of chemical-related events such as explosions, releases, and combustion, the substances and the form of a substance used in a chemical procedure must be identified.
