The pharmaceutical industry is expected to meet the needs of patients around the world at a cost they can afford while minimizing the environmental footprint. Merck is deeply committed to supporting the development of sustainable and environmentally benign processes for its commercialized products. We strive to develop synthetic processes according to the 12 principles of Green chemistry and engineering. Development of commercial processes that follow the Green by Design guidelines are encouraged and recognized by our senior management. The key to success in conserving resources and reducing costs is the ability to develop and leverage innovative science. Several examples from different programs in our pipeline, demonstrating Merck ’s commitment to sustainable and benign processes, will be discussed.
