Criteria for Evaluation for Eco-Material and the Case Study in Japan
Criteria for evaluation for eco-material and the case study in Japan. An environmental performance of the material is described clearly from the viewpoint of international mutual agreement with the environmental label of ISO. The eco-material is evaluated with Law on Promoting Green Purchasing and the ISO environmental label, etc. in Japan. However, the doubt is caused in the validity of the united evaluation of all materials by the same functional processing module. However, enough inventory data doesn't exist to evaluate the material and the product under the present situation. Moreover, the difficulty of what the life time of the product uniformly defines is pointed out. Then, it is necessary to choose the proper procedure from social and a scientific viewpoint to make the criteria of the eco-material. The validity of the criteria is referred in the this study, and the note to make a fairer criteria is presented. The relation to the general person's recognition to the criteria and this was shown by using the method of Analytical Hierarchy Process(AHP). In addition, we introduce the evaluation scheme of the eco-material based on the LCA technique of the Ministry of Land, Infrastructure and Transport.
