泰国是稻米生产和出口的主要国家之一；因此，现在有大量的稻草留在田里，通常被焚烧，以便于快速种植下一季作物。该研究评估了泰国使用稻草生产生物二甲醚的生命周期温室气体(GHG)排放。分析了稻草生物二甲醚利用的两种方案，即作为柴油发动机的车用燃料和作为家用液化石油气的补充。结果表明，与柴油和液化石油气替代燃料相比，稻草生物二甲醚在两种方案下的温室气体排放量分别可减少约14-70%和2-66%。如果稻草被认为是水稻种植的副产品，稻草种植将是温室气体排放的主要来源，占稻草生物二甲醚生产温室气体排放总量的50%左右。讨论了影响稻草生物二甲醚生产温室气体性能的几个因素，并提出了提高稻草生物二甲醚生产和利用温室气体性能的措施。
Thailand is one of the leading countries in rice production and export; an abundance of rice straw, therefore, is left in the field nowadays and is commonly burnt to facilitate quick planting of the next crop. The study assesses the life cycle greenhouse gas (GHG) emissions of using rice straw for bio-DME production in Thailand. The analysis is divided into two scenarios of rice straw bio-DME utilization i.e. used as automotive fuel for diesel engines and used as LPG supplement for household application. The results reveal that that utilization of rice straw for bio-DME in the two scenarios could help reduce GHG emissions by around 14–70% and 2–66%, respectively as compared to the diesel fuel and LPG substituted. In case rice straw is considered as a by-product of rice cultivation, the cultivation of rice straw will be the major source of GHG emission contributing around 50% of the total GHG emissions of rice straw bio-DME production. Several factors that can affect the GHG performance of rice straw bio-DME production are discussed along with measures to enhance GHG performance of rice straw bio-DME production and utilization.
