Chemical Engineer

Chemical engineers solve problems associated with the production and use of chemicals and biochemicals. It is based on the principles of chemistry, physics, biology and mathematics and is responsible for the production of chemicals for use in our everyday lives. Chemical engineers strive to create and develop the best possible methods to manufacture useful products and services. They respond to society's growing demands for new innovative products and for improved use of our limited natural resources.

Chemical engineering is a highly transferable skill and there are plenty of opportunities to specialise. Experience and a postgraduate degree will often ensure rapid career progress.

Why it matters?

Chemical engineers play a key role in shaping in our lives, from refining oil, to cleaning water, to developing one of the world’s most popular and widely used stationary products, the Post-it Note. The Post-it Note was developed by Spencer Silver in 1968 who was a chemical engineer working on pressure-sensitive adhesives for the aerospace industry. Spencer accidentally added too much chemical reactant to the experiment and thus became the adhesive used in Post-it Notes.
