چکیده :

Iran possesses a significant potential for the production of bioethanol from lignocellulosic residues of agricultural and horticultural products. This study, conducted using crop production data published by the Iranian Ministry of Agriculture and global FAO statistics, examines the past, present, and future challenges and prospects in bioethanol production. It particularly focuses on the production of bioethanol from non-food parts of crops, considered as waste materials, including peels, bagasse, straw, husks, and wood. The study revealed that in 2021, a total of 7.3 billion tons of lignocellulosic residues, comprising 5.3 billion tons of on-farm residues and 2 billion tons of post-process residues, were produced worldwide. This quantity of lignocellulosic residues had the potential to produce 4.2 billion tons (3,069 billion liters) of bioethanol in 2021. In the same year, Iran produced 30.7 million tons of lignocellulosic residues, with the potential to generate 11 million tons (14 billion liters) of bioethanol, accounting for 0.4% of the global potential. The highest residue density was observed in Region 4, including the eastern provinces of Iran, followed by Region 1, encompassing the northern provinces, in 2021. Among on-farm residues, corn straw, rice straw, and wheat straw ranked first to third, respectively. Among post-process residues, chickpea husks, plum pits, and rice husks had the highest potential in Iran over the nine-year period from 2012 to 2021.
