Abstract

This study aimed to study a process of Vannamei culture in Ongkharak Subdistrict, Bang Pla Ma District, Suphanburi ,to analyze and compare GHGs emission from each process and consequently, to address guidelines for reducing GHGs emission from the process. Life Cycle Analysis was used in this study so as to calculate GHGs emission from raw material e.g. fuel, chemicals, shrimp food used in the process of preparation, transportation, feeding and shrimp distribution. There are fifteen agricultures used in this study.


The results showed that GHGs emission from land preparation accounting for 1,095.1872 kgCO2eq/67 days, or 1.8253 kgCO2eq/kgproducts and that from transportation about for 151.5019 kgCO2eq/67 days, or 0.2525 kgCO2eq/kgproducts. Where as GHGs emission from feeding the shrimp about 1,344.0901 kgCO2eq/67 days, or 2.2401 kgCO2eq/kgproduct and that from the shrimp distribution accounting for 13,865.1076 kgCO2eq/67 days, or 23.1085 kgCO2eq/kgproducts. In total, the GHGs emission from the process of culture is 16,455.8868 kgCO2eq/67 days, or 27.4264 kg-CO2eq/kgproducts. Guidelines for GHGsemission reduction are for instance. 1) Planning sharing and monitoring the use of raw materials e.g. fuel, chemical, shrimp food 2) Controlling quantity of small shrimp in the wheel to not too dense. 3) Cooperation between each agriculture for setting shrimp market and buy shrimp food.
