The aim of this paper is to provide a review of the most promising opportunities for sustainable biofuel generations in Bangladesh. Many researchers provide their opinions with their experimental results, but there has been no overall statistics and potentiality for the sustainable production of biofuel such as bioethanol and biodiesel in Bangladesh. The paper reviews the recent statistical conditions and the potential of biodiesel and bioethanol production in Bangladesh compared to other countries. Basically, the paper focuses on the potentiality of various biofuel feedstocks like as soybean oil, mustard oil, cottonseed oil, sesame oil, coconut oil, algae, rubber seed oil, jatropha, karanja oil, castor, bahera, neem, rice bran oil, pitraj and also different types of residues, crops, fruits, wastes. Among these reviewed papers, it is revealed that Bangladesh can generate annually about 0.16 million tons of edible oil. In addition, Bangladesh has the ability to produce about 1001881 tons of biodiesel from 2387500 tons of non-edible oil. Also, 0.04 million metric tons of biodiesel can be made from rubber seed oil. On the other hand, about 32 metric tons of bioethanol from 65.36 metric tons of agricultural crop residues, and about 143670082.36 gallons of bioethanol from 10.22 million metric tons of potato that is enough to meet the demand of 5% bioethanol blend annually. Furthermore, Bangladesh can produce 31.65 million metric tons of bioethanol from rice residue and 1.34 million metric tons of crude rice bran oil from rice husk of the paddy. It is conjectured that these annual production of various feedstocks can be used as major sources of biofuel and also can meet the demands of biofuel in Bangladesh.
本文旨在综述孟加拉国可持续生物燃料生产最具前景的机遇。许多研究人员结合其实验结果发表了观点，但孟加拉国生物乙醇和生物柴油等生物燃料可持续生产的总体统计数据和潜力尚不明确。本文回顾了孟加拉国与其他国家相比生物柴油和生物乙醇生产的最新统计情况及潜力。基本上，本文聚焦于各种生物燃料原料的潜力，如大豆油、芥菜油、棉籽油、芝麻油、椰子油、藻类、橡胶籽油、麻风树、卡兰贾油、蓖麻、诃子、印楝、米糠油、毗黎勒，以及不同类型的残渣、作物、水果、废弃物。在这些综述论文中，研究表明孟加拉国每年可生产约16万吨食用油。此外，孟加拉国能够利用238.75万吨非食用油生产约1001881吨生物柴油。同时，橡胶籽油可生产4万吨生物柴油。另一方面，65.36吨农作物残渣可生产约32吨生物乙醇，1022万吨马铃薯可生产约143670082.36加仑生物乙醇，足以满足每年5%生物乙醇混合燃料的需求。此外，孟加拉国可利用稻壳残渣生产3165万吨生物乙醇，利用稻谷壳生产134万吨粗米糠油。据推测，这些各种原料的年产量可作为生物燃料的主要来源，也能够满足孟加拉国生物燃料的需求。
