Abstract: Design for Environment (DfE) optimizes the relationship and
interaction of the economic system and the environmental system, and strives to
produce a sustainable development and enterprise integration. The driving force
behind DfE includes customers, international agencies, and governmental
agencies, who are all stake holders in the environmental well being. The
methodologies and tools of DfE generally fall under three loose categories,
namely, decision making, design support, and material flow. In DfE, there are a
number of enablers for decision making, examples of which include end-of-life
strategies and Life Cycle Assessment (LCA). With the development of DfE,
sophisticated design support methodologies and tools are necessary for the
early stage of design regarding the environmental impact, working as guidance
to the design engineers. The three main design support constituents, discussed
in this paper, include LCA, Design for Disassembly, and Expert Systems.
Environmental impact resulting from modern industry has spurred interest in the
material and energy flows of industry systems. These flows are viewed not only
to be fundamental to environmental problems, but also as agents of financial
success. The scope of DfE has three elements, namely, strategy, guidelines and
procedures, and application. It is noted that the next frontier of DfE is the
incorporation of society models that include technology, government, customers,
recyclers, and their respective interaction. This paper presents recent
developments and current activities of DfE, specifically, the areas of
decision-making, design support, material flow analysis and application.
Additionally, a brief discussion of future trends is presented and observations
are made on how to further realize DfE in industry and in the entire society
while protecting the environment.
