Environmental evaluation of railway material changes using LCA

Abstract

As means of the reduction of the environmental load, the change of the materials of the product is thought about. In order to grasp the load quantitatively, life cycle assessment is performed. In this report, the matter that we should pay attention to about environmental load of the materials of the railway is explained. In addition, as examples of evaluation of CO2 reduction effect, geo-polymer concrete production and the maintenance reduction effect resulting from the use of carbon contact strips on pantograph head are shown.
