As the world tries to create new ways of living efficiently and eliminating waste, scientific exploration continues to provide answers to the engineers who construct our homes, generate our fuel, process our food, and build our products. Sustainability is, perhaps, the most important issue facing our society today, with much of the world still turning to coal and oil to fuel its growth, buildings continuing to be built based on antiquated designs, and industry continuing to create environmental hazards and turning natural habitats into unsafe zones. The authors delve into the engineering aspects of sustainability and the principle of zero waste, not just from a philosophical or hypothetical point, but they present detailed methods for eliminating waste in many important areas of engineering, such as civil engineering, agriculture, construction, and energy production. If nature is recyclable and, by its condition, perfect, in the sense that it cannot be wasteful or destructive without renewing itself, and if humans are, by their actions, responsible for the waste and devastation that we see in the world today, it seems that a return to natural pathways would be the logical way to achieve sustainability and zero-waste. The authors explore these issues and questions, offering mathematical models, new processes, and new, sustainable products for achieving this ultimate, desired result: Zero-Waste Engineering.
