Abstract:
Material life cycle engineering is a frontier interdiscipline based on the infrastructure of materials science, manufacturing science and environment science. It is an eco-design oriented applied engineering, in the purpose of meeting performance requirement, saving resource and protecting environment by means of hazardous substance substitution, green process planning, cleaner production, resource recycle, et al. throughout the whole industrial supply chain to achieve a systematic optimization for material products during the whole life cycle. In this article, the author reviewed the development and application status of material life cycle engineering, performed a comprehensive analysis of the fundamental technology to explain the linkage among life cycle engineering, eco-design and other critical techniques, so as to point out that eco-design is the key elements to deploy life cycle engineering theory. This article also proposed the framework and well as implementation procedure of eco-design for the specific situation of Chinese material industry. Moreover, the quantitative assessment method for materials performance, resource consumption and environment impact have been established based on performance – requirement matrix, Exergy analysis model and life cycle assessment, respectively, which forms a material product oriented eco-design methodology with a full metrics. In sum, this article provides further theoretic foundation to the eco-material development and application.
