3.4 Practical Frameworks and Tools

Design for Environment

DfE is an eco-efficiency strategy that allows a company to move beyond end-of-the-pipe and in-the-pipe concepts like pollution control and pollution prevention to a systems-based, strategic, and competitively critical approach to environmental management and protection. It is a proactive approach to environmental protection in which the entire life-cycle environmental impact of a product is considered during its design. DfE is intended to be a subset of the Design for X system, where X may be assembly, compliance, environment, manufacturability, material logistics, and component applicability, orderability, reliability, safety and liability prevention, serviceability, and testability.Thomas E. Graedel and Braden R. Allenby, Industrial Ecology (Englewood Cliffs, NJ: Prentice Hall, 1995), 186–87. Design for an end goal allows properties necessary to achieve that goal to be integrated most efficiently into a product's life cycle. Hence DfE, like concurrent engineering, becomes a critical tool for realizing many aspirations of frameworks, such as cradle-to-cradle, or other tools, such as green supply chains.

Within the domain of DfE are such concepts as design for disassembly, refurbishment, component recyclability, and materials recyclability. These concepts apply to reverse logistics, which allow materials to be collected, sorted, and reintegrated into the manufacturing supply stream to reduce waste. Reverse logistics become especially important for green supply chains.

DfE originated in 1992, mostly through the efforts of a few electronics firms, and is described by Joseph Fiksel as "the design of safe and eco-efficient products". These products should minimize environmental impact, be safe, and meet or exceed all applicable regulations; be designed to be reused or recycled; reduce material and energy consumption to optimal levels; and ultimately be environmentally safe when disposed. In accomplishing this, the products should also provide a competitive advantage for a company.
