Second-generation technology (2G) is currently the industrial route that is being developed with the potential to meet the demand for biofuels and bioproducts. The technology studied in the present work is based on the non-food processing of sugarcane straw, which is unlike the bagasse processing route (a lignocellulosic residue) that is commonly used in boilers for steam and electricity generation. In the last years, cellulosic ethanol plants worldwide include the utilisation of corn stover, sugarcane bagasse, wood waste and plant residues. Therefore, a communication based on industrial aspects using sugarcane straw is important in order to expand the knowledge regarding this promising technology. The main objective of this work included listing the results obtained in a cellulosic-ethanol production industry using sugarcane straw, located in the Northeast region of Brazil and taking into account the efficiency of pre-treatment, enzymatic hydrolysis and fermentation processes and comparing these results with data found in the literature regarding studies with similar efficiency. It was possible to observe that the production of ethanol from sugarcane straw at an industrial scale achieved a productivity of 200 l of ethanol per tonne of biomass, exhibiting 90, 70 and 85% of pre-treatment, hydrolysis and fermentation efficiency, respectively.

第二代技术（2G）是目前正在开发的工业路线，具有满足生物燃料和生物产品需求的潜力。当前工作中研究的技术基于甘蔗秸秆的非食品加工，这与通常用于蒸汽和发电锅炉的甘蔗渣加工路线（木质纤维素残留物）不同。近年来，全世界的纤维素乙醇工厂包括利用玉米秸秆，甘蔗渣，木材废料和植物残渣。因此，使用甘蔗秸秆进行基于工业方面的交流非常重要，以扩大有关这一有前途技术的知识。这项工作的主要目的包括列出使用甘蔗秸秆在纤维素乙醇生产行业中获得的结果，设在巴西东北地区，并考虑到预处理，酶水解和发酵过程的效率，并将这些结果与文献中有关效率相似的文献中的数据进行比较。可以观察到，以工业规模从甘蔗秸秆生产乙醇可实现每吨生物质200升乙醇的生产率，分别具有90％，70％和85％的预处理，水解和发酵效率。
