GREEN CHEMISTRY: AN UNIQUE RELATIONSHIP BETWEEN WASTE AND RECYCLING

ABSTRACT Green chemistry consists of chemicals and chemical processes designed to reduce or eliminate negative environmental impacts. The usage and re-production of the chemicals produces reduced waste products, non-toxic components and improved quality. Green chemistry is a highly effective motivation in pollution prevention because it applies innovative scientific approaches in real-world environmental situations. Chemical products and processes should be designed to the highest level of this phenomenon and be cost-competitive as well as cost-effective in the world market. Green Chemistry applications: Source of Reduction & Prevention of Chemical Hazards, Design of chemical products which are less hazardous to human health and the environment, Use of feedstocks and reagents that are less hazardous to human health and the environment, Design of syntheses and other processes to be of less energy consumption and materials intensive with high atom economy & low E-factor), Use of feedstocks derived from annually renewable resources or from abundant waste, Design of chemical products for increased, more facile reuse or recycling, Reuse or Recycle of Chemicals, Treatment of Chemicals to make them less hazardous, Disposal of Chemicals Properly including radioactive wastes. The chemicals that are less hazardous to human health and the environment are less toxic to organisms and ecosystems, not persistent or bio-accumulative in organisms or the environment and inherently safer with respect to handling and use to make green ecosystem.
