SummaryHumans have the ability to reduce air pollution. In this unit, students develop an understanding of modern industrial technologies that help clean up and prevent air pollution, and they have the opportunity to engage in solutions by writing environmental action letters.
Environmental and chemical engineers face the challenge of devising new techniques to prevent air pollution from manufacturing and industry. This challenge is compounded by the potential for added clean-up steps or costs to the manufacturing processes. Engineers must be creative in designing new pollutant recovery methods and industrial technologies that clean up and prevent air pollution that are efficient and cost-effective.
