It is essential to evaluate the environmental impacts of materials or products properly for improving the global environment. However the typical method called Life Cycle Assessment (LCA) has many problems. Especially, it is crucial that various kinds of environmental impacts cannot be integrated. We present an attempt to use the exergy concept to integrate them. We classified the different types of exergy and analyzed the impact of the life cycle of beverage containers (aluminum can, PET bottle) and generation of electricity as examples, focusing on chemical and nuclear materials.
