Advancements in Green Chemistry: A Comprehensive Study

1. Introduction to Green Chemistry

Green chemistry or sustainable chemistry are chemical products and processes that help to reduce or eliminate the use and generation of hazardous substances. The green chemistry concept was first introduced by Anastas and Warner in 1999 and is referred to as the Twelve Principles of Green Chemistry. The driver behind green chemistry protocols is to recognize pollution prevention through atom utilization and to reduce the adverse effects of industry on the environment and improve sustainability. The present approach is articulated to fall into three different levels of pollution prevention, and green chemistry should encompass all of them. This approach leads to businesses, governments, and communities where green-chemistry processes and principles are integrated and funded on a systematic basis at various stages of discovery, technology, and product/application development with a prospective end.

This essay is about the importance of green chemistry and summarizes the recent advancements in green chemistry for some organic reactions. This essay aims to provide information, particularly for study in chemistry, the 12 principles of green chemistry, and the advancement of green chemistry in recent years. Based on the 2019 year, the United Nations have announced that the world is expecting to have a massive change for the environment and resources, and support the Global Sustainable Development. As a result of environmental health and the depletion of natural resources, the world is demanding more attention to the products’ characteristics, services supportive, and more importantly, they are using eco-friendly products. At the same time, professionals in the field of green chemistry are emphasizing the properties or the importance of green chemistry in university curriculum.

2. Principles and Concepts of Green Chemistry

Introduction Following are some of the concepts and principles of green chemistry: 1. Waste prevention is better than waste treatment or clean-up. 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 practicable, synthetic methodologies should be manufactured so that the production and use of chemicals are done in a manner that reduces the hazard to humans and the environment. 4. Designing safer chemicals: Chemical products should be designed to affect their desired function while minimizing their 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 should be acknowledged that generate the least waste and the minimum emissions. In some processes, it may be essential to use a solvent. However, if a protocol uses a solvent, it may be greener to adopt a solvent that is able to be recycled or reused. Green chemistry originators Paul Anastas and John C. Warner developed twelve guiding principles as a framework for incorporating sustainability into the research and design of new chemical products and processes. Each tenet is summarized below.

3. Applications of Green Chemistry in Various Industries

5. Degradable Fiber: Ecospun is the first degradable fiber available in the American textile market. Cotton fiber is established and is an ecopatent.

4. Electronics Industry: Green chemistry principles can be applied to the electronics industry by using renewable resources, incorporating biological processes, using non-corrosive and low-energy chemical processes, and avoiding chemicals that have potential environmental effects. Green bio-compatible implantable electrodes can be used for cochlear implants and pacemakers. The computer industry reuses old computer parts by remanufacturing their original functions. They also make computer enclosures and other products that directly compete with steel and wood. The parts of the computer are reusable. It is a non-profitable company. Green chemistry activities are a priority in the industry.

3. Energy Production: In the field of fuel production (alternative sources of energy), the principles of green chemistry are implemented to reduce the use of petrochemicals. For example, bio-ethanol is used as a fuel. Natural resources like air, water, ethanol, and sunlight are utilized for the production of hydrogen gas. The Heliocentris 9 student kit is designed to teach the principles of green hydrogen energy.

2. Agriculture Industry: Nitrogen-fixing plants like Alfalfa are used as a cheap and easy source of nitrogen nutrients. Green fertilizers like nitrogen-fixing plants are used in the agriculture industry as an alternative to commercial fertilizers.

1. Pharmaceutical Industry: The pharmaceutical industry implements the principles of green chemistry to improve manufacturing processes and reduce pollution. For example, ibuprofen is synthesized by reducing waste production. West Pharmaceutical Services has manufactured a stopper rubber that requires fewer petrochemicals to produce.

The applications of green chemistry across various industries include the following.

4. Challenges and Future Directions in Green Chemistry

In order to reduce heat and power loss for vehicle cooling, heating, and air conditioning, experimental studies are required to characterize and assess in detail how different insulating materials and hose system configurations affect the thermal efficiency of an automobile. A change in the baseline brake system’s design can be implemented to optimize a regenerative braking system that captures and stores part of the kinetic energy dissipated in the form of heat during the braking process. Auxiliary gasoline-powered engines are promising alternative approaches when drive range extender technology is combined with pure electric vehicles. Finally, the rear wing control effect of a single-seater formula car is considered to understand the aerodynamic drag force, which affects the vehicle’s overall energy consumption and impacts fuel consumption efficiency. Clearly, future trends and trends will continue to focus on different advances in low-emission energy technologies such as solar energy, natural fuel, and bioenergy production, development, and storage.

All over the world, researchers are working in green areas. There are already some advances and limitations of the green revolution. The novice paradigm of ultrafast photodetectors, semiconductor devices, green batteries, energy storage, powerful antimicrobes, non-viral gene delivery strategies, famous catalyst materials, and many industrial applications significantly improved by reducing the influence of green chemistry by other people. For example, preparation of 0D, 1D, and 2D PbI2 nanostructures for dielectric applications, preparation of MnO2/MPA NPs changed from organic synthesis agent capping synthesis by solvents can be used in many chemical reactions with low pollution. These nanoparticles can reduce waste generation and replace substances. Research areas still need to constantly improve to meet the needs of increasing society, and encouraging progress in these areas is above all human thinking and understanding.
