Book excerpt: This third volume in a four-volume set offers new theories and applications for the diagnosis and treatment of mental disorders. Having laid the groundwork in the first two volumes, the authors now embark on significant, real-life scenarios that apply their philosophy to mental disorder treatments. The goal of the project is to take the industry toward sustainability, not just in terms of the chemical engineering used to create medicines, but also environmentally, economically, and personally. Their unique approach uses a more holistic and philosophically cohesive method for treating mental disorders, making the industry "greener" and the patient healthier. The four volumes in "The Greening of Pharmaceutical Engineering" are: Volume 1: Practice, Analysis, and Methodology Volume 2: Theories and Solutions Volume 3: Applications for Mental Disorder Treatments Volume 4: Applications for Physical Disorder Treatments This ground-breaking set of books is a unique and state-of-the-art study that only appears here, within these pages. A fascinating study for the engineer, scientist, and pharmacist working in the pharmaceutical industry and interested in sustainability, it is also a valuable textbook for students and faculty studying these subjects.
