This book offers unparalleled insight into the convergence of sustainability and pharmaceutical product development, with a specific focus on optimization processes. By addressing the urgent demand for more environmentally conscious and efficient strategies in the drug development industry, particularly in an era where the world faces the mounting challenges posed by climate change, the book provides a comprehensive guide for integrating sustainability principles throughout the pharmaceutical product lifecycle, directly contributing to the United Nations Sustainable Development Goals (SDGs), such as SDG 12 (Responsible Consumption and Production) and SDG 13 (Climate Action). The chapters cover key topics, including the application of green chemistry, eco-design principles, sustainable sourcing of raw materials, waste reduction strategies, and the use of renewable energy in pharmaceutical manufacturing processes. Throughout the book, case studies are integrated, offering practical insights and concurrently highlighting the economic and environmental advantages of sustainable practices, thereby addressing skepticism regarding the feasibility and profitability of such initiatives. The book also discusses regulatory considerations, ethical implications, and the challenges and opportunities associated with moving toward more sustainable practices in pharmaceutical development. Importantly, this book seeks to solve the problem of the knowledge gap and lack of practical resources for professionals in the pharmaceutical industry who aspire to implement sustainable and optimized processes. This work consolidates a network of professionals and scholars keenly focused on future sustainability challenges, developing enhancement methodologies, and sharing successful strategies for implementing eco-friendly practices in pharmaceutical sectors worldwide, ultimately contributing to the global effort to achieve the SDGs by 2030. With a focus on pharmaceutical professionals, researchers, academicians, and students, the book serves as a valuable reference for those involved in drug development and process optimization. Policymakers and regulatory bodies might also find it insightful, as it addresses current landscapes, challenges, and future directions in sustainable pharmaceutical product development.
