A ″cradle-to-wheel" life cycle analysis was carried out to investigate the environmental profile of bioethanol (EtOH) production from lignocellulosic wheat straw (WS) and its use as transport fuel in E10 (10% of EtOH and 90% of gasoline) and E85 (85% of EtOH and 15% of gasoline) vehicles. The aims of this study were: (i) to evaluate the environmental performance of the whole WS-EtOH supply chain and (ii) to identify the best performing feedstock for a prospective bio-refinery network in Campania Region (Southern Italy). A comparison of WS-EtOH system against the fossil counterpart (gasoline passenger car) and similar bio-based production-use chains was conducted to fulfil one of the main goals of EnerBiochem and BioPoliS projects: investigating the environmental profitability of a bio-refinery system in Campania Region. Starting from the use of residual feedstock (wheat straw) or the revaluation of marginal lands (cultivation of dedicated perennial giant reed or annul fiber sorghum), through the investigation of an advanced lignocellulosic conversion processes, this work assesses the environmental feasibility of bio-energy production in Campania Region.

The WS-E10 environmental profile was driven by the gasoline input in the blend, whilst the WS-E85 results showed the relevance of the crop phase. The comparison of the different blends and the gasoline-fuelled car highlighted for E10-blends similar profiles for almost all the impact categories, nearly overlapping with the conventional vehicle. Differently, for E85 vehicles, the differences between the bio-based systems appeared amplified according to the specific impacts of the feedstock supply and the conversion steps. On the whole, Fiber Sorghum-E85 system showed the worst environmental profile whilst WS-E85 entailed the best performance.

进行了“摇篮到轮式”生命周期分析，以研究木质纤维素麦草（WS）生产生物乙醇（EtOH）的环境状况及其在E10中用作运输燃料（10％的EtOH和90％的汽油）的用途。 ）和E85（85％的EtOH和15％的汽油）车辆，这项研究的目的是：（i）评估整个WS-EtOH供应链的环境绩效，以及（ii）找出性能最佳的原料坎帕尼亚地区（意大利南部）的潜在生物精炼网络，将WS-EtOH系统与化石对应物（汽油乘用车）和类似的基于生物的生产使用链进行了比较，以实现EnerBiochem的主要目标之一和BioPoliS项目：调查坎帕尼亚地区生物精炼系统的环境盈利能力。通过研究先进的木质纤维素转化过程，从使用残留的原料（麦草）或对边缘土地进行重估（培育多年生的专用巨型芦苇或年长纤维高粱）开始，这项工作评估了生物能源的环境可行性。在坎帕尼亚地区生产。

WS-E10的环境概况受掺混物中汽油的输入驱动，而WS-E85的结果表明了作物期的相关性。对于E10型混合燃料，将不同混合燃料与汽油燃料汽车进行比较后，得出几乎所有冲击类别的​​相似曲线，与常规车辆几乎重叠。不同的是，对于E85车辆，根据原料供应和转换步骤的特定影响，生物基系统之间的差异似乎会放大。总体而言，Fiber Sorghum-E85系统显示出最差的环境特征，而WS-E85具有最佳性能。
