A Chemical Engineer is a professional who applies principles of chemistry, physics, and mathematics to solve problems related to the production and use of chemicals. They design processes to create materials like plastics, fuels, and pharmaceuticals, ensuring that these processes are efficient, safe, and environmentally friendly. Their work often involves scaling up laboratory experiments to industrial production levels. In addition to designing processes, chemical engineers also focus on improving existing systems. They may work with biotechnology to develop new medicines or with energy companies to create cleaner fuels. Their expertise is crucial in industries such as food production, water treatment, and materials science.
