Biochemical Engineering: Overview
Biochemical engineering is a multidisciplinary field that combines principles of biology, chemistry, and engineering to develop processes and technologies involving biological materials. It plays a critical role in industries like pharmaceuticals, food and beverage, biofuels, and environmental management. The focus is on designing, optimizing, and scaling up processes that utilize biological organisms or biomolecules.
Key Areas in Biochemical Engineering
