Chemical Engineers once qualified, work in a wide range of companies and fields. They produce a wide variety of products ranging from fuels and petrochemicals to inorganic bulk chemicals, food and beverage, household products such as soaps and detergents, pharmaceuticals, polymers and fine chemicals. Their job is to transform efficiently and safely raw materials into useful products with minimum environmental impact. Chemical Engineers with knowledge in environmental engineering also work in waste management, waste treatment, water treatment, agriculture, consulting and renewable energy industries.Chemical engineering with environmental engineering is a branch of engineering which deals with both chemical production and the manufacture of products through chemical processes including the application of environmental engineering to ensure factors related to environmental sustainability are taken into consideration during design and manufacturing. This includes designing equipment, systems and processes for refining raw materials and for mixing, compounding and processing chemicals to make valuable products in a sustainable manner.
