Sai Life Sciences Sustainability Report 2020

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
