Chemical engineering originated over 100 years ago due to the need for chemical processors during the Industrial Revolution. It grew out of mechanical engineering and involves applying principles of chemistry, physics, biology and math to efficiently and safely convert raw materials into useful products through continuous processing. Modern chemical engineering has expanded beyond process engineering to include developing high-performance materials for applications like aerospace, automotive, biomedical and more through interdisciplinary fields like biomedical engineering. The field of chemical engineering continues to grow as it plays a key role in innovation and mass production across many industries.
