Abstract: Biodiesel is one of the most promising alternative fels for transportation in Thailand. It is a very good candidate for substituting petroleum-diesel in engines because of its similar properties. Biodiesel can be produced from various vegetable or animal oils and palm oil is found to be a good suitable raw material for biodiesel production in Thailand. The aim of this study was to analyze the energy performance and evaluate greenhouse gas emission of palm biodiesel production in Thailand. The biodiesel production system was divided into four stages: the oil palm plantation, crude palm oil production, palm oil refinery, and biodiesel production which separated into two different processes; the production of biodiesel from crude palm oil (CPO) and palm stearin as raw material. The transportation activity was also included in this study: transportation of fresh fruit bunch (FFB) to milling factory, transportation of CPO to refinery plant, transportation of palm stearin to biodiesel production plant, and transportation of biodiesel to point of use. For each stage, the material and energy flows are presented and discussed. The greenhouse gas emissions are inventoried. The production of biodiesel from CPO, the net energy balance (NEB) and net energy ratio (NER) of biodiesel and co-products are 49734.68 MJ/ton biodiesel and 5.04, respectively. The NEB and NER of biodiesel (without co-product) are 25770.17 MJ/ton biodiesel and 3.1 0, respectively. The biodiesel production from palm stearin, the NEB and NER of biodiesel and its co-product are 114313.73 MJ/ton biodiesel and 5.58, respectively. The NEB and NER of biodiesel (without co-product) are 13135.80 MJ/ton biodiesel and 1.53, respectively. The life cycle GHG emissions from production of biodiesel were found 1.26 kg C02-eg per kg biodiesel for biodiesel production from crude palm oil and 51.3 kg C02-eg per kg biodiesel for biodiesel production from palm stearin.
