An Introduction

In order to attain sustainability, the area of "green chemistry," which is still in its early stages of development, works on a molecular basis. The topic has attracted a lot of attention in the last ten years because it can use chemical inventions to concurrently achieve both economic and ecological targets. Current primary themes in green chemistry comprise decreasing global dependence on non-renewable energy sources, lowering commercial carbon footprints, collapsing waste production, and utilising vast materials (garbage) that nobody needs, like carbon dioxide using these assets in novel ways. A destructive greenhouse gas which is speeding up global warming is carbon dioxide, which has a well-deserved reputation for being one. Green chemistry has played a key role in developing strategies for using CO2 as a source rather than letting it accumulate as trash in our atmosphere.


Definition of Green Chemistry

The definition of green chemistry is the utilisation of a collection of guidelines to lessen or completely stop the usage of hazardous materials in the development, production, and usage of chemical products.


According to the concept of green chemistry, the alternative tool, novel chemical reactivities and reaction settings must be developed in order to potentially benefit chemical synthesis in the areas of resource efficiency, energy efficiency, product selection, operational simplification, and environmental and health protection.


Principles of Green Chemistry

Twelve fundamental principles in green chemistry can indeed be divided into two categories: "Reducing Hazard" and “Reducing the Global Footprint”. They are:

  • Prevention

  • Atom economy

  • Less hazard

  • Generating safer chemicals

  • Safer solvents

  • Design of Energy efficiency

  • Usage of renewable feedstock

  • Reduce derivatives

  • Catalysis

  • Plan of degradation

  • Real-time analysis for pollution prevention

  • Toxic and Accident prevention


Uses and Examples of Green Chemistry

Uses of Green Chemistry are popular in many sectors, including pharma, firms, and even homes, to reduce the usage of dangerous or toxic materials. Following are a few examples of green chemistry:

  • Environmentally safe green solvents, like water, alcohol, and others, are employed in chemical production as effective alternatives to hydrocarbon solvents.

  • Kerosene or gasoline was formerly utilised for dry cleaning; however, nowadays, chlorinated liquids are utilised instead, which is a further incredibly helpful development of green chemistry.

  • The manufacture of nylon frequently involves the usage of adipic acid. However, the benzene used to make this adipic acid is toxic. As a result, researchers created genetic modifications of bacteria to serve as a catalyst in the production of adipic acid from glucose.

  • Since it burns less easily than diesel and gasoline, biodiesel, which is made from renewable sources, is less harmful.

  • In the therapy of type-2 diabetes, novel biocatalysts are created utilising an enzymatic method that has the same capability as existing medications in terms of garbage reduction, yield improvement, and safety. This does away with the need for a metallic catalyst.

  • The creation of olefin metathesis is among the most trustworthy scientific breakthroughs.


Significance of Green Chemistry

Green Chemistry adopts a life cycle strategy, taking into account waste creation, safety, energy usage, and toxicity in the initial phases of chemical development and manufacturing to lessen the influence of the development phase, its usage, and its removal.


Developing green chemistry is a key strategy for creating a model for sustainable economic development. As is well known, hazardous substances are poisonous to people, plants, and animals, as well as contribute to a number of atmospheric problems such as ozone layer depletion, global warming, smog production, pollution, etc. The promotion of eco-friendly chemical production processes and green chemistry is absolutely necessary.


Interesting Facts

  • The father of green chemistry is recognised as Anastas. In order to reduce pollution, green chemistry was created in the 1990s.

  • The ground-breaking book Green Chemistry: Theory and Practice was then co-authored by Paul Anastas and John C. Warner in 1998.

  • Robert Grubbs, Richard Schrock, and Yves Chauvin—shared the 2005 Nobel Prize in Chemistry for olefin metathesis development.

  • According to the present green chemistry, researchers from all around the world are working to create sustainable methods. The government and businesses are also keen on this area, which could aid in the sustainable expansion of our economy.


Key Features to Remember

  • Green chemistry is an extremely creative technique to create non-toxic, non-hazardous compounds while also preserving the planet. Green chemistry is crucial to the sustainability of our planet.

  • Green Chemistry plans to take into account the entire chemical life cycle.

  • Green chemistry aims to eliminate the underlying risk of chemical goods and operations by designing them from the ground up.

  • Green Chemistry functions as a coherent set of guiding principles or planning standards.

FAQs on Green Chemistry The Alternative Tool

1. Explain a novel emerging field in green chemistry?

A relatively emerging field of generating innovative green chemistry is microwave-assisted reactions in water. Their benefits include ease of handling, quick reaction times, and excellent energy economy. Unfortunately, for the technique to be genuinely useful, big microwave reactor growth is required.

2. Where is green chemistry used?

In the chemical sector, green chemistry is employed in procedures including treating wastewater, electrolysis, drying of products, and distillation. Currently, the majority of the energy utilised by the chemical industry comes from fossil fuels, but there are a number of methods for reducing the consumption of these non-renewable power sources.

3. What is the common problem when water is used as a solvent?

Low solubility of the reactant, reagents, or products is a common problem for reactions in water. A new technology, like combined microwave and ultrasonic irradiation, might be able to resolve this.
