An Assessment Model of Green Design Analysis For Photocatalyst Products of Environmental Protection

Photocatalyst utilizes light to induce strong oxygenation on a catalyzer, which decomposes the attached dirt and organic matter into water and carbon dioxide. It has functions of disinfection, antiseptic, self-clean, deodorization and is non-pollutant and safe. There are more and more new environmental protection products on the market applying photocatalyst techniques. Therefore, the purpose of this study is to establish an assessment model of green design analysis for photocatalyst products of environmental protection. The results of this study can serve as a reference and basis for industrial designers who are working on the development of Photocatalyst products of environmental protection. It can also increase consumers´ acceptance and reliability toward this new item so as to improve the success of new products launches. The methodology of this study adopts related literature review, deep interview from experts and a case study of the photocatalyst air cleaner. Through the processes of MET matrix analysis, green design checking list and LiDS green design strategy wheel analysis of product life cycle, the result clearly appears the changes of photocatalyst products of environmental protection. As a result, it can become the important rules for photocatalyst product development of environmental protection in the future. Meanwhile, the result of the study indicates that the catalyst reacting in the course does not waste any energy and thus the application of photocatalyst will advance and expand the functions and advantages of the products.
