Sugarcane bagasse (SCB), a major and abundantly available byproduct of sugarcane processing industries is presently being used for energy generation. However, its rich resource content makes it a perfect feedstock for production of various value-added products. In this communication, Microcrystalline Cellulose (MCC), a partially depolymerized cellulose is in vogue due to its versatile physical properties which holds substantial applications in the pharmaceutical industries was produced from the surplus available SCB. Experiments were designed to optimize MCC production from SCB using three different chemical methods namely MCC1, MCC2 and MCC3 by varying chemicals and reaction conditions. Relatively higher yield of cellulose (0.34 g/g SCB) and MCC (0.32 g/g SCB) were observed with MCC2 method, followed by MCC3 (cellulose 0.32 g/g SCB; MCC 0.31 g/g SCB) and MCC1 (cellulose 0.30 g/g SCB; MCC 0.28 g/g SCB). Fourier transform infrared spectroscopy (FT-IR) showed good correlation with commercial grade MCC for the characteristic functional groups. X-ray diffractograms (XRD) showed 79.8%, 84.1% and 87.4% crystallinity for MCC1, MCC2 and MCC3, respectively. The morphological analysis of all the three MCC samples correlated effectively with the standard MCC. EcoScale analysis yielded score greater than 75, in which MCC2 scored the maximum. However, Life cycle analysis depicted the impacts of MCC production methods on various environmental impact categories, where MCC3 method showed relatively less environmental impact in terms of global warming (27% less than MCC2). MCC3 further characterized with X-Ray Photoelectron Spectroscopy, Thermogravimetry analysis (TGA), Differential thermal analysis (DTA) and Differential scanning calorimetry (DSC) depicted its characteristic properties. The sustainability analysis functioned as a valuable tool to assess the environmental impact of the process, prior to scaling up.

甘蔗渣（SCB）是甘蔗加工业的一种主要且大量可得的副产品，目前正用于发电。但是，其丰富的资源含量使其成为生产各种增值产品的理想原料。在这种交流中，部分解聚的纤维素微晶纤维素（MCC）由于具有广泛的物理特性而在流行，它由多余的SCB制成，在制药工业中具有重要的应用。设计了实验，通过使用三种不同的化学方法（MCC1，MCC2和MCC3），通过改变化学药品和反应条件来优化SCB的MCC生产。使用MCC2方法观察到相对较高的纤维素（0.34 g / g SCB）和MCC（0.32 g / g SCB）产量，其次是MCC3（纤维素0.32 g / g SCB; MCC 0）。31 g / g SCB）和MCC1（纤维素0.30 g / g SCB; MCC 0.28 g / g SCB）。傅里叶变换红外光谱（FT-IR）显示与商业级MCC的特征官能团具有良好的相关性。X射线衍射图（XRD）显示MCC1，MCC2和MCC3的结晶度分别为79.8％，84.1％和87.4％。所有三个MCC样品的形态分析均与标准MCC有效相关。EcoScale分析得出的得分大于75，其中MCC2得分最高。但是，生命周期分析描述了MCC生产方法对各种环境影响类别的影响，其中MCC3方法在全球变暖方面显示出相对较小的环境影响（比MCC2低27％）。MCC3进一步通过X射线光电子能谱，热重分析（TGA），差示热分析（DTA）和差示扫描量热法（DSC）描绘了其特性。可持续性分析是在扩大规模之前评估过程对环境的影响的宝贵工具。
