Chemical engineering combines science with engineering practice and design. Biotechnology uses knowledge at the molecular level of living systems to devise strategies to solve important practical problems like controlling disease and making the environment safer. Chemical engineers inculcate biotechnology to make production on a larger scale. These integrated skills can be applied to environmental management, agriculture and natural resource management, as well as a range of biological-based products and processes. Chemical engineers can promote processing industries using minimal energy to produce less waste and maximize environmental safety. This degree helps student to gain skills in better management of the environment; preventing, diagnosing and curing disease; improving crop plants and livestock; detecting pollutants and contaminants; and using organisms to produce chemicals, including drugs and food, and agrichemicals.
