Green and Sustainable Chemistry

Green nanotechnology can affect the proposal of nanomaterials and products by reducing pollution from the production of the nanomaterials, taking a life cycle approach to nanoproducts to estimate and reduce where environmental effects might occur in the product chain, designing toxicity out of nanomaterials and using nanomaterials to treat existing environmental problems. Green nanotechnology has built on the principles of green chemistry and green engineering. Green nanotechnology applications might also involve a clean production process, such as producing nanoparticles with sunlight; the recycling of industrial waste products into nanomaterial.

\r\n Pollution Prevention and Control which aims to monitoring, modeling, risk analysis and preventive measurements of the pollution. It aims to remove ambiguities and discrepancies, ensure clearer environmental benefits, promote cost-effectiveness and encourage technological innovation. It is an action that reduces the amount of contaminants released into the atmosphere. Prevention of pollution conserves natural resources and can also have significant financial benefits in large scale.

The idea of . Green chemistry takes a stride further and builds new concepts for chemistry and engineering to design chemicals, chemical processes and products in a way that circumvents the production of toxic substances and waste generation. New catalytic reaction procedures continue to develop to advance the objectives of Green Chemistry, while methods such as photochemistry, microwave and chemical feedstock’s, solvents, reagents, and products. <span style="\&quot;font-size:" 10pt;="" color:="" rgb(51,="" 51,="" 51);="" text-decoration-line:="" none;\"="">Green chemistry is the design of processes and chemical products that lessening or reduces the generation of hazardous substances.

Reactions play the most major role in synthesis. Green Chemistry appeals for the development of new chemical reactivity’s and reaction conditions that can potentially provide benefits for chemical syntheses in empathies of resource and energy efficiency, operational ease, product selectivity, and health and environmental safety. Some of greener syntheses is the development of tandem and cascade reaction processes that incorporate as many reactions as possible to give the final product in single operation. In biocatalysis where the potential effectiveness of various catalysts such as enzymes, whole cells, and catalytic antibodies for organic synthesis has become more recognized.

Green energy, at times called renewable or sustainable energy comes from natural sources like wind, water, and sunlight. It is more environmentally friendly than other types of energy and doesn’t contribute to climate change or global warming. Green energy is generally defined as the energy that comes from natural sources such as sunlight, rain, plants, wind, waves, algae and geothermal heat. These energy resources are renewable in nature. Renewable energy sources have lesser impact on the environment which produces pollutants such as greenhouse gases as by-product, causative to climate change. Improvements in renewable energy technologies have lowered the cost of solar panels, wind turbines and other sources of green energy. Research into renewable, non-polluting energy sources is progressing at such a fast pace. The most common types of green energy include solar power, wind power, wind power, geothermal energy, biomass and biofuels.

\r\n Green engineering approaches the design, commercialization of products and the use of processes and products in a manner that concurrently reduces the amount of pollution that is generated by a source, reduces exposures to potential hazards, and promotes sustainability as well as protecting human health without effecting the economic viability and efficiency. Fundamental Principles of green engineering comprises engineering processes and products use systems analysis, and assimilate environmental impact assessment tools; minimising the depletion of natural resources; assure that all energy and material inputs and outputs are safe and compassionate as much as possible; Create solutions further than current technologies to improve, innovate, and invent to achieve sustainability.

Green food production often suggests organic farming practices a few centuries ago. This type of farming uses a small area of land for crops and another area for grazing beef, sheep, and goat. Farm entities were almost always independent with no use of pesticides or herbicides and the only fertilizer used was manure. Organic farming wills ensembles the notion of a green technology. Primary, secondary, and tertiary processing techniques are discovered to convert raw produce into value-added foods and ingredients. Primary processing techniques such as cleaning, grading, dehulling, sorting, and milling are used as initial step in processing most of the grains. One of the most promising technological approaches to decrease environmental footprint in food processing is the use of enzymes.  Enzymes speed up reaction rates and results in savings in terms of time, energy, and cost. Food enzymes provide advantages in terms of specificity, sensitivity, their relative non-toxicity, high activity at low concentrations, and ease of inactivation.

Waste management are the activities and actions required to manage waste from its inception to its final disposal. Recycling is the procedure of collecting and processing materials. Recycling includes the three steps mainly those are Collection and processing, Manufacturing, purchasing New products made from Recycled Materials. Many benefits are there by recycling process mainly prevents pollution by reducing the need to collect new raw materials, Saves energy, increases economic security by tapping a domestic source of materials.

As part of a rapidly growing field of study, the applications of ultrasound in green chemistry and environmental applications have a promising future. Compared to conventional methods, ultrasonication can bring various benefits, such as environmental friendliness cost efficiency, and compact, on-site treatment. Ultrasonic technology summarizes the main studies and innovations reported in recent research that has utilized ultrasound methods in environmental analysis, water, and sludge treatment, soil and sediment remediation to air purification.

The green economy is defined as economy that aims at reducing environmental risks and ecological scarcities, and that aims for sustainable development without degrading the environment. An inclusive green economy is an alternative to today's dominant economic model, which exacerbates inequalities, encourages waste, triggers resource scarcities, and generates widespread threats to the environment and human health. The concept of the green economy has emerged as a priority for many governments. By transforming their economies into drivers of sustainability, these countries will be primed to take on the major challenges of the 21st century -from urbanization and resource scarcity to climate change and economic volatility.

The term “green” manufacturing can be looked at in two ways: the manufacturing of “green” products, particularly those used in renewable energy systems and clean technology equipment of all kinds, and the “greening” of manufacturing — reducing pollution and waste by minimizing natural resource use, recycling and reusing what was considered waste, and reducing emissions.

\r\n Natural Products Chemistry is a branch of chemistry which deals with the isolation, identification, structural elucidation, and study of the chemical characteristics of chemical substances produced by living organisms. Natural products are small molecules produced naturally by any organism including primary and secondary metabolites. They include very small molecules, such as urea, and complex structures, such as Texel. They might be isolable in small quantities but having interesting biological activity and chemical structures, natural product synthesis stances an interesting challenge in organic chemistry.

\r\n Nano science and nanotechnology are the study and application of extremely small things which are used across all the other science fields such as chemistry, biology, materials science, physics and engineering. Nano science is the study and manipulation of materials at atomic, molecular and macromolecular scales, where properties differ expressively at a larger scale. Nanotechnology is the characterisation, design, production and application of structures, devices and systems by controlling shape and size at nanometre scale. Understanding of physics and chemistry and processes at the Nano scale is relevant to all scientific disciplines, engineering and medicine, biotechnology, from chemistry and physics to biology, chemistry, automotive systems, aerospace and robotics. Materials chemistry involves the use of chemistry for the design and synthesis of materials with interesting or potentially useful physical characteristics, such as magnetic, optical, structural or catalytic properties

\r\n Environmental chemistry encompasses the study of chemicals and chemical processes within the air, water, and soil. Environmental chemistry is more than just water, air, soil, and chemicals. People in this field use math, biology, genetics, hydrology, engineering, toxicology.  Green Chemistry is nothing but use of chemistry techniques and methods that decrease to eliminate the use or generation of feedstock, solvents, reagents, by-products, etc., that are hazardous to human health or environment. Green Chemistry is an approach to the synthesis, processing and use of chemicals that reduces risk to human health and the environment. Environmentally benign solvents have been one of the important research areas of Green Chemistry with great advances seen in chemical reactions. New catalytic processes continue to develop to advance the goals of Green Chemistry, while techniques such as microwave and ultrasonic synthesis as well as in situ spectroscopic methods has been broadly used, leading to spectacular results.
