Abstract—This research measured the eco-efficiency of Thai

growing-fishing pig farms. Eco-efficiency indicators were developed by the previous literatures and field observation contributed for the investigation of the potential environmental impact in a material flow analysis. Eco-Eco-efficiency degrees and trends at economic and environment performances for Thai growing-fishing pig farms during 2010-2012 was calculated. The eco-efficiency degrees and trends were assessed by World Business Council for Sustainable Development recommendation and Snapshot graph plot, respectively. The results showed that the highest and lowest eco-efficiency degrees of Thai growing-fishing pig farms were drug and energy consumptions, respectively. The eco-efficiency of Thai growing-fishing pig farms snapshot showed that most eco-efficiency indicators were located in Fully-Eco-Efficiency. However, only wastewater production indicator was located in Haft-eco-efficiency because the growing-fishing pig farm required the water for cleaning twice a day. Biogas production from the growing-fishing pig farms wastewater should be recommended for enhancing approach of eco-efficiency performance. Index Terms—Eco-efficiency, growing-fishing pig, farm
