57 Adopting green chemistry We have introduced Green Chemistry principles, through which we measure and monitor the greenness of the process right from the development phase. We developed a ‘Greenness Index, ’ which is a computational model to determine the greenness of a process, in 2019. Adoption of Green Chemistry principles in process development Processes evaluated for greenness index Water Conservation • Specific Water Consumption • Quality of Waste Water Resource Conservation • Atom Economy • Reaction Mass Efficiency • E-Factor • Carbon Efficiency • Chemical Yield Solvent Management • Greenness of Solvent • Specific Solvent Consumption • Number of Solvents Used • Solvent Recovery
