Engineers are problem solvers, and chemical engineers over the last century have been instrumental in development of smaller, faster computer chips...innovations in recycling, treating disease, cleaning water, and generating energy...the processes and products that chemical engineers have helped create touch every aspect of our lives. They believe this role in everyday life contributes to the success of chemical engineers in general, who tend to excel in the private sector because of their solutions-based skills training for problems with uncertainty and limited knowledge.
