Life Cycle Assessment Estimation for Eco-Management of Co-Generation Systems

摘要

A LCA (life cycle assessment) scheme for any industrial activity system is introduced to estimate the quantitative load on the environment with the aid of the NETS (numerical environment total standard) method proposed by the authors as a numerical measure. Two kinds of environmental loads respecting fossil fuel depletion as input resources to the System and global warming due to CO_2 emission as output are taken into account in the Present eco-criterion, in which the total eco-load (EcL) value is calculated from the Summation of respective environmental load factors on the whole process in a life cycle of The system.
