Industrial symbiosis (IS) activities within an industrial complex can enhance environmental and economic efficiencies. This study proposed a simplified life cycle assessment (LCA) methodology as an effective tool with which to evaluatethe reduction of environmental impact of IS activities. In this method, the variation of resources and energy consumptionsbefore and after IS activities are proposed to simply evaluate its lifecycle environmental impacts. The simplified LCAwas applied to an IS case between an industrial waste incineration plant and a steam production plant of a paper millfirm in the metropolitan city Ulsan. The system boundary and inventory were set for this IS, and an environmental impactassessment was carried out by standard and proposed LCA methods. The results showed that the environmental impactsafter IS decreased in all impact categories with regard to the consumption reduction of boiler fuel used at the paper mill. Furthermore, the performance of environmental improvement activities such as IS can be simply evaluated by onlyconsidering the input and output changes in the environmental improvement activities. In this IS case study, theenvironmental impact was decreased by 11.7% (weighted impact base). This was due to the utilization of waste heatgenerated from an incineration plant in the process of the paper mill firm.
