Chemical engineers are professionals who apply principles of chemistry, physics, and mathematics to solve problems related to the production and use of chemicals. They design processes for large-scale manufacturing, develop new materials, and improve existing products. Their work often involves creating safe and efficient methods for producing chemicals, fuels, and pharmaceuticals. In addition to designing processes, chemical engineers also focus on environmental sustainability. They work on projects that reduce waste and energy consumption, ensuring that industrial processes are safe for both people and the planet. Their expertise is crucial in industries such as petroleum, food processing, and biotechnology.
