Abstract
This paper provides an overview of aplicability 12 principles and future trends of 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. They are used exclusively chemicals and chemical processes that do not have negative consequences for the environment. It is based on twelve principles that can be used to initially create or recreate molecules, materials, reactions and processes that are safer for human health and the environment. The processes of the Green Chemistry that have been developed to date include almost all areas of chemistry, including organic, inorganic, biochemistry, polymer, toxicology, environmental, physical, technological, etc. Through the several prevailing trends of the green program such as catalysis, biocatalysis and the use of alternative: renewable feedstock (biomass), reaction media (water, ionic liquids and supercritical fluids), reaction conditions (microwave irradiation) and new synthetic pathways (photocatalytic reaction), the dual goals – environmental protection and economic benefit can be achieved. This article shows examples of the prevailing trends in ways that Green Chemistry reduces the impact of chemical processes and technologies on the environment.
Highlights
Accelerated progress in science and technology in the second half of the twentieth century has led to significant economic development and an increase in living standards in developed parts of the world
The new laws and regulations aim to protect the ecosystem from harmful chemicals, while the chemical community through the processes of green chemistry is geared towards developing new compounds and processes that are less dangerous to human health and the environment
This paper aims to contribute to a better understanding of the principles and processes underlying green chemistry, and through examples and dominant trends to point to the ways in which green chemistry reduces the impact of chemical processes and technology on the environment
Summary
Accelerated progress in science and technology in the second half of the twentieth century has led to significant economic development and an increase in living standards in developed parts of the world. Such economic development has caused considerable environmental degradation, which is manifested by more pronounced climate change, the emergence of ozone holes and the accumulation of non-destructive organic pollutants in all parts of the biosphere. Green or Sustainable Chemistry is a term related to the creation of chemical products and processes that reduce or eliminate the use and production of harmful substances. 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
