Increasing awareness about sustainability has compelled the recent researchers to explore different methods for evaluation. Conventionally the sustainability of a process was majorly dependent on the economics feasibility. Recently need of incorporation of environmental and social concerns in overall sustainability assessment has been realized. Authors in their prior work has published a framework for performing sustainability assessment of biomass processing enterprises. The present work is on selection of sugarcane valorization pathways based on the sustainability index using the same framework. Six alternative routes are compared based on their economic, environment and social criteria. Life cycle assessment of each process is performed as per ISO 14040/44 to evaluate the environmental criteria. Integrated method of value function (MIVES) is used for consolidation of different indicators and criteria. Amongst the process alternatives considered for assessment, 1G2G ethanol route is observed to have highest sustainability index (0.864) owing to relatively lower environmental impact whereas first generation butanol production route (1GRS) had the least sustainability index of 0.090 on account of decreased yield and less products. Sensitivity analysis performed on the model showed no significant change in the ranking of the alternatives.

甘蔗增值：基于可持续性指数的工艺路线选择
对可持续性的认识不断提高，迫使最近的研究人员探索不同的评估方法。传统上，一个过程的可持续性主要取决于经济可行性。最近已经意识到需要将环境和社会问题纳入整体可持续性评估。作者在他们之前的工作中发布了一个对生物质加工企业进行可持续性评估的框架。目前的工作是基于使用相同框架的可持续性指数选择甘蔗增值途径。根据经济、环境和社会标准比较了六种替代路线。根据 ISO 14040/44 对每个过程进行生命周期评估，以评估环境标准。价值函数的综合方法（MIVES）用于合并不同的指标和标准。在考虑进行评估的工艺替代方案中，观察到 1G2G 乙醇路线的可持续性指数最高（0.864），因为环境影响相对较低，而第一代丁醇生产路线（1GRS）的可持续性指数最低，为 0.090，原因是产量下降和更少产品。对模型进行的敏感性分析表明，备选方案的排名没有显着变化。864），因为对环境的影响相对较低，而第一代丁醇生产路线（1GRS）由于产量下降和产品减少，可持续性指数最低，为 0.090。对模型进行的敏感性分析表明，备选方案的排名没有显着变化。864），因为对环境的影响相对较低，而第一代丁醇生产路线（1GRS）由于产量下降和产品减少，可持续性指数最低，为 0.090。对模型进行的敏感性分析表明，备选方案的排名没有显着变化。
