Chemical and Biological Engineering is a branch of engineering that combines principles from chemistry, biology, physics, and mathematics to develop processes and products. This field focuses on transforming raw materials into valuable products, such as fuels, pharmaceuticals, and food, while ensuring safety and sustainability. Professionals in this field design and optimize processes for large-scale production, often using equipment like reactors and separators. They also work on environmental issues, such as waste treatment and pollution control, to minimize the impact of industrial activities on the environment. Key topics include thermodynamics, reaction engineering, and bioprocessing.
