开发了减少泰国一家湿榨厂生产毛棕榈油产生的温室气体排放量的替代方法。2010年，有生物气捕集的米尔斯厂（4家米尔斯厂）和没有生物气捕集的米尔斯厂（2家）生产1吨粗棕榈油平均产生935千克二氧化碳当量的温室气体排放。有和没有沼气捕获的污水处理厂产生的温室气体排放量分别占温室气体排放总量的64%和47%。其余排放主要来自收购新鲜水果串。建立沼气回收系统必须是减少温室气体排放的第一步。它可以减少温室气体排放量373 kgCO 2 eq/t的CPO。带有生物气收集的米尔斯厂的163 kgCO 2 eq/t CPO的温室气体排放的主要来源是在废水进入生物气回收系统之前用于冷却废水的开放式池塘。减少温室气体排放可以通过以下方式实现：（i）使用废水分散装置进行冷却，（ii）使用有盖池塘，（iii）提高沼气回收系统的性能，以及（iv）将稳定池改为曝气泻湖。通过采用备选办法一至四，可分别减少216、208、92.2和87.6千克二氧化碳当量/吨粗棕榈油的温室气体排放量。
Alternative methodologies for the reduction of greenhouse gas (GHG) emissions from crude palm oil (CPO) production by a wet extraction mill in Thailand were developed. The production of 1 t of CPO from mills with biogas capture (four mills) and without biogas capture (two mills) in 2010 produced GHG emissions of 935 kg carbon dioxide equivalent (CO2eq), on average. Wastewater treatment plants with and without biogas capture produced GHG emissions of 64 and 47% of total GHG emission, respectively. The rest of the emissions mostly originated from the acquisition of fresh fruit bunches. The establishment of a biogas recovery system must be the first step in the reduction of GHG emissions. It could reduce GHG emissions by 373 kgCO2eq/t of CPO. The main source of GHG emission of 163 kgCO2eq/t of CPO from the mills with biogas capture was the open pond used for cooling of wastewater before it enters the biogas recovery system. The reduction of GHG emissions could be accomplished by (i) using a wastewater-dispersed unit for cooling, (ii) using a covered pond, (iii) enhancing the performance of the biogas recovery system, and (iv) changing the stabilization pond to an aerated lagoon. By using options i-iv, reductions of GHG emissions of 216, 208, 92.2, and 87.6 kgCO2eq/t of CPO, respectively, can be achieved.
