E-Factors across the chemical Industry Mass Intensity = mass of all materials used excluding water/mass of product kg (kg product) Solvent Intensity = mass of all solvent used excluding water/mass of product k g (kg product) % Solvent Intensity = mass of all solvent/mass intensity kg (kg product) Water Intensity = mass of all water used/mass of product = kg (kg product) E factor = Total mass of waste produced/Total mass of product produced
Green Chemistry • Green chemistry is the design of chemical products and processes that reduce or eliminate the use and generation of hazardous substances. • Application: to advance the implementation of green chemistry and engineering principles into all aspects of the chemical enterprise • Education and Research • Education • Industrial Implementation
Green Chemistry = Pharmaceutical Hazard & Pollution Free • “Green chemistry is the science that introduces new substances into the world and we have a responsibility for their impact in the world.”
Fundamentals of Green Chemistry • Increase awareness and understanding of green chemistry principles, alternatives, practices and benefits. • Integrate the principles of Green Chemistry & Green Engineering into the curricula. • Equip chemists to meet tomorrow’s scientific challenges. • Risk = f(Hazard*Exposure)

Importance of Green Chemistry in Nanotechnology In recent years, the development of efficient green chemistry methods for synthesis of nanoparticles has become a major focus of researchers. An eco-friendly technique for production of well-characterized nanoparticles. Production of metal nanoparticles using organisms ( living or dead) Plants seem to be the best candidates and they are suitable for large- scale biosynthesis of nanoparticles. Nanoparticles produced by plants are more stable and the rate of synthesis is faster than in the case of microorganisms.
Conclusion • The Unique Green Chemistry Applications: • Non-toxic manufacture of metallic nanoparticles • Solvent Consumption Reduction • Safer Environment • Cost Reduction
