本研究应用物质流成本会计（MFCA），以确定材料和能源损失的成本，以及技术改进的机会，以提高淀粉和乙醇的生产率在泰国。结果表明，由于乙醇生产涉及多个转化过程，其损失成本高于淀粉生产。对技术改进方案进行了评估，并将其扩大到全国范围，以评估增加木薯原料以实现AEDP目标的可能性。结果表明，超重力（VHG）和同步糖化发酵（SSF）工艺可以提高工厂的生产能力和效率。从木薯浆中生产乙醇也可以在满足可再生和替代能源发展计划（AEDP）和利用淀粉加工副产品方面发挥重要作用，增加其价值并抵消淀粉生产厂的损失成本。该场景中的这些改进选项可以帮助减少生产乙醇以实现AEDP目标所需的木薯原料量。提高产量可以满足原料需求，而不需要土地用于种植园扩张，减少木薯出口和分配更多的糖蜜用于乙醇生产。(C)2015爱思唯尔有限公司版权所有。
This research applied Material Flow Cost Accounting (MFCA) to identify the costs of material and energy loss, as well as the opportunity for technology improvement to increase productivity in starch and ethanol productivity in Thailand. The results showed that ethanol production incurred more loss cost than starch production because it entails several conversion processes. Scenario for technology improvement was evaluated and expanded to the broader scale of the whole country to assess the possibility of increasing cassava feedstock in order to meet the AEDP target. The result shows that the Very High Gravity (VHG) and Simultaneous Saccharification and Fermentation (SSF) processes can increase plant capacity and efficiency. Ethanol production from cassava pulp can also play an important role in meeting the Renewable and Alternative Energy Development Plan (AEDP) and utilizing by-product from starch processing, increasing its value and offsetting loss cost from starch production plant. Those improved options in the scenario can help to reduce cassava feedstock amount required to produce ethanol for the AEDP target. Yield improvement can satisfy feedstock requirement without the need of land for plantation expansion, reduce cassava export and allocation of more molasses for ethanol production.
