This study was conducted to provide an improving direction of K-EIP(Korean Eco-Industrial Park) construction project by company's voluntary participation. For this purpose, we investigated and analyzed the status of domestic eco-industrial park projects from various literatures, foreign EIP cases and FGI(Focus Group Interview). The key issues to construct a voluntary K-EIP are the lack of experts, the difficulties of commercialization financing, and so on. In this study, therefore, the programs to resolve these problems in K-EIP construction project were suggested at the level of government and corporation.

Industrial complexes in Korea have been vigorously established by economic development plan and development policy of industry in 1960s. Recently, Korean government has promoted Eco Industrial Park (EIP) project to recycle by-products and wastes in industrial park In this study, we analyzed the physical and chemical properties for the sludges discharged from A industrial complex. And we investigated the economic feasibility and environmental impact of sludge to energy facilities. The analysis results indicated that the petrochemical industry were 92% in sludge production, the highest treatment amount was landfill, followed by incineration and recycling and then ocean disposal. Wastewater sludge and process sludge samples are collected and analyzed to use as basic data on economic feasibility and environmental impact. Weighted average heating value of sludge samples was 3,891kcal/kg. Based on this data, installation and operation costs, operation returns of operating the drying facility are estimated, compared with cogeneration facility. And this study examines how the payback period of each simulation(total 8 case) with the important parameter changes. As a result, it was found that what needs the shortest payback period is 3years with connection of drying facility and cogeneration facility based on the government's financial subsidy system.
