Waste acid and alkali solutions are discharged the most from printed circuit board, surface treatment and metalworking companies in the Banwol-Sihwa EIP, South Korea. However, most of companies are sold to consignment enterprises instead of self-recycling because they are composed of uncompetitive small companies, which then becomes the main cause of environmental pollutions and costs increase. This paper aims to evaluate economic value of recycled waste acid and alkali solutions by applying Life cycle cost (LCC) methodology. As a result, it proves that this recycling network has high and stable income potential. Furthermore, for exact economic evaluation, copper price trend prediction was evaluated by correlation and regression analysis about copper price variability of the most sensitive factor coming up with sensitivity analysis.<br>
