The authors make their point persuasively: Opportunities to increase profits by saving resources and/or reducing pollution abound, especially in old industries or in facilities designed before the first OPEC embargo. Innovation, ingenuity, and leadership have enabled the firms in these case studies to take advantage of these opportunities. Their competitive economy, based on efficiency and profit maximization, can and does promote the values of energy conservation, resource efficiency, and pollution reduction needed to build a sustainable world. While too dry for bedside reading, and while not detailed at all in the sense of engineering design, this book tells an important story. With increased competition from overseas, and with a need to manage all their resources even more carefully, they need success stories to spread the philosophy and the methods of making profits from pollution prevention.
