Environmentally conscious consumers and environmental protection legislation have been driving manufacturers to design, produce, and dispose products in a more environmentally responsible manner. The purpose of environmentally conscious design and manufacturing is to develop methodologies for designing products from \"\"green\"\" principles, from conceptual design through consumer use and ultimately to the end-of-life management. Incorporating environmentally conscious design poses many challenges. The greatest challenge is how to change conventional design and manufacturing and ensure sustainable production systematically and cost effectively. Progress has been made towards many environmentally oriented “Design for X” approaches, which target specific aspects of product life-cycle. One of the limitations of existing methodologies is that most approaches focus on minimizing the reprocessing cost or maximizing the recovery values only at the end-of-life management stage. However, less than one-third of the reprocessing costs depend on optimization of the reprocessing process, while the remaining costs are highly dependent on the early product design phase.
