What are the 5 principles of green chemistry?

Abstract

  • Prevention of waste/by-products.
  • Maximum incorporation of the reactants (starting materials and reagents) into the final product.
  • Prevention or minimization of hazardous products.
  • Designing of safer chemicals.
  • Energy requirement for any synthesis should be minimum.
  • Selecting the most appropriate solvent.

What is the strategy of green chemistry?

Green chemistry aims to design and produce cost-competitive chemical products and processes that attain the highest level of the pollution-prevention hierarchy by reducing pollution at its source. *Chemicals that are less hazardous to human health and the environment are: Less toxic to organisms.

What is Reach Annex XVII?

The Annex XVII of REACH regulation contains the list of restrictions of certain hazardous substances, mixtures and articles for their marketing and use on the European market.
