He was an engineering department head at Crawford Russel, an adjunct professor at Yale University, and a course director at the Center for Professional Advancement. In 1995 he was invited to teach as a Fulbright Scholar. He was a book reviewer for American Scientist, received the Control Hall of Fame Award in 2001 and the Life Time Achievement Award of ISA in 2005. Today, he is the president of the consulting firm Liptak Associates P.C. His work includes the design and optimization of industrial processes, energy conservation, pollution prevention, and safety-related projects. 

Section I provides an introduction to green chemistry and green engineering. Section II provides examples of pollution prevention heuristics for chemical processes. Heuristics of the two most important unit operations, reactors and separators, are covered. Section III introduces readers to the concept of environmental fate and transport and prediction of environmental fate properties. Understanding of environmental fate and transport is important for exposure assessment and also is essential for evaluating environmental performance of processes and products during process development and design. 

A hazard is anything that will produce an adverse effect on human health and the environment. In environmental risk assessment, the hazard component generally refers to toxicity. Exposure is the quantitative or qualitative assessment of contact to the skin or orifices of the body by a chemical. Traditional pollution prevention techniques focus on reducing waste as much as possible however, risk assessment methods used in pollution prevention can help quantify the degree of environmental impact for individual chemicals. This approach provides a powerful tool that enables engineers to better design processes and products by focusing on the most beneficial methods to minimize all aspects of risk.
