Abstract
Map Ta Phut Industrial Estate (MTPIE), located in Rayong province, eastern of Thailand, was developed by the state enterprise, Industrial Estate Authority of Thailand, Ministry of Industry, to serve industries that use natural gas as the main raw material development. This research presents the eco-efficiency evaluation of the petroleum and petrochemical group (PP) in the MTPIE. There are 31 factories in the PP group, which can be divided into three categories: upstream, intermediate, and downstream. The eco-efficiency values of the PP group were evaluated according to the World Business Council for Sustainable Development recommendations. The comparison of eco-efficiency values between three industrial categories in the PP group demonstrates that factories in the downstream category obtained particularly good eco-efficiency results concerning material consumption, water use, and hazardous waste generation. The eco-efficiency trends of the PP group were simply analyzed by snapshot graph. With the availability of the data on environmental indicator, the water use indicator was selected to be an example indicator for analyzing the eco-efficiency trends of the PP group. The eco-efficiency snapshot concerning the net sale and water use during the year of 2003–2005 showed that the eco-efficiency trends of the PP group in the MTPIE shifted from half eco-efficient in 2004 to fully eco-efficient in 2005. This research can provide a basic framework on eco-efficiency evaluation for the industrial sector in Thailand, which will feed into strategic development, and would enable public participation in the discussion on branch developments and contributions to national trends.
