Discuss the principles of environmental engineering in the context of chemical processes, focusing on pollution prevention, waste minimization, and sustainable development. Explore the design and operation of treatment technologies for air emissions, wastewater, and solid waste, considering factors such as treatment efficiency, resource recovery, and regulatory compliance. Evaluate the environmental impact of chemical processes, including factors such as greenhouse gas emissions, toxic releases, and ecosystem disruption, and propose strategies for pollution control and environmental remediation. Analyze the role of life cycle assessment and eco$-$efficiency metrics in evaluating the environmental performance of chemical products and processes.
