54 Process development and technology We have increasingly adopted green chemistry principles during the process development of every mid-late phase project that we work on, with the objective of identifying opportunities for environmental protection and conservation. Green chemistry principles help us to understand resource consumption, generation of waste and the efficiency of processes. The indicators that contribute to the greenness of a process are tracked and monitored by process development teams and are also included as part of our technical package. We have continued to recognize best practices and recognize teams that develop better processes through the Green Process of the Year Award. Environment friendly execution of batches in Unit 3 Our aim is to continuously improve the manufacturing process to minimize environmental impact and improve workplace safety. The R&D team undertook laboratory scale investigations, followed by quality assurance. After completing the critical steps, we utilized a systematic approach to gain customer approval, complete change control documentation and then scale-up for commercial quantities. The process now uses 43% less water, solid waste to the landfill has been cut by approximately 45% and we have eliminated usage of n-heptane solvent. The environmentally-friendly process is well established with the completion of 13 batches producing the desired quality and yield. Green Process of the Year 2021 • 85% reduction in specific water consumption • 82% reduction in specific solvent consumption • Avoided use of dichloromethane
