The bagasse of guayule, obtained after extraction of natural rubber and resins, can be used to produce 2nd generation fermentable sugars and lignin. For this purpose, four pretreatment technologies were applied to deconstruct the guayule bagasse: diluted acid (DA), steam explosion (SE), organosolv (OS), and the steam explosion followed by alkaline washing (AW). The obtained lignocellulosic pulp underwent enzymatic hydrolysis (EH) to produce glucose. The conditions that gave the highest hydrolysis yield were assessed. A mass balance was elaborated for all processes which were compared on the basis of sugars yield, water and chemical consumption, and energy expenditure footprint. The greatest amount of glucose (133 g kg⁻¹ of dry guayule bagasse, corresponding to 71% enzymatic hydrolysis yield) was obtained using SE followed by AW, whereas SE and OS had lower yields (104 g and 106 g kg⁻¹, respectively). The highest overall monomeric sugars yield, including xylose, was obtained by DA (317 g kg⁻¹) followed by OS (243 g kg⁻¹) pretreatment, although the sugar streams must be purified in both processes by removing the acid and the solvent, respectively. SE is a process with a limited requirement of chemicals and energy input, which are significantly higher for AW and for OS, respectively.

银胶菊的甘蔗渣是从天然橡胶和树脂中提取出来的，可用于生产第二代可发酵糖和木质素。为此，采用了四种预处理技术来解构银菊蔗渣：稀酸（DA）、蒸汽爆破（SE）、有机溶剂（OS）和蒸汽爆破后碱洗（AW）。获得的木质纤维素纸浆经过酶水解 (EH) 以产生葡萄糖。评估了产生最高水解产率的条件。在糖产量、水和化学品消耗以及能源消耗足迹的基础上对所有过程进行了详细的质量平衡。最大葡萄糖量（133 g kg ^-1干银胶菊蔗渣，对应于71％的酶水解产率）使用SE，然后是AW，而SE和OS的产率较低（分别为104 g和106 g kg ^-1）。通过 DA (317 g kg ^-1 ) 和 OS (243 g kg ^-1 ) 预处理获得最高的总单糖产量，包括木糖，尽管糖流必须在两个过程中通过去除酸和溶剂进行纯化， 分别。SE 是一个对化学物质和能量输入的要求有限的过程，AW 和 OS 的要求分别显着更高。
