According to increase in a waste scrap, a process is noticed in which a waste scraps is consumed for sheet steel production within severe restriction of impurities concentration. In this study, evaluation of the effect on environmental load decline by LCA is applied to this new recycling technology.<BR>Target of this study is not for closed loop recycling system like aluminum can for drink but for open loop recycling system in which many industries are concerned. Authors suggest taking the interindustry-relations table for open loop recycling system. Evaluation made in this research is based on it. By setting up I/O boundary, though increase of environmental load is predicted to be high comparing to those which are assumed as non-open recycling system, still there is a sufficient effect for it. As the result of the analysis, curtailment was estimated that energy consumption and CO<SUB>2</SUB> emission are 16.8 GJ per ton waste scrap and 1.2 t per ton waste scrap, respectively.
