Chemical engineering thereby plays the most important role in shaping our world by applying principles of chemistry and physics, combined with a little mathematics and biology, to produce processes that convert raw materials into valuable products. The spectrum ranges from drug chemicals to energy solutions, thus being an indispensable sector in the era of modern industry.
It lies at the heart of studying chemical processes and reactions, which engineers design to optimize and scale up with regards to efficiency, safety, and environmental friendliness- for example, designing the production of biofuels from waste material in ways that minimize our dependence on fossil fuel use while reducing the amount of waste streams.
This field also focuses on innovation. Recent developments in nanotechnology and material science have made new routes for the design of materials with tailored properties for certain applications open to the world. Envision lightweight yet strong materials for aerospace applications or catalysts that would speed up reactions, thus making chemical production much more effective.
Outside of traditional chemical manufacturing, the chemical engineer has become a core participant in inter-disciplinary projects solving important problems in every sphere of this world's lives. Whether it is providing a better water-treatment technology so that clear, fresh water may be obtained, or whether it is designing new materials for clean renewable energy technologies, their expertise will be vital for creating sustainable solutions.
