Lignocellulosic biomass (LCB) is a sustainable energy resource to produce biofuels and biobased chemicals without affecting the global food security. The recalcitrant nature of LCB hinders enzymatic hydrolysis, thus pretreatment is a critical step. Choline chloride:glycerol (ChCl:Gly) is a promising solvent for LCB delignification. The innovation aspect of the project consists of microwave-assisted ChCl:Gly pretreatment to delignify rice straw in conjunction with a sequential cultivation of Candida tropicalis and Saccharomyces cerevisiae to ferment sugars into ethanol with the aim of developing a zero waste biorefinery. The project consists of seven research objectives with overall aim of training the Fellow for academic expertise, professional skills and multidisciplinary collaboration. The project activities are divided into seven work packages (WPs). WP1: obtain overall training and Knowledge Inter-Transfer. WP2: Raw material preprocessing, pretreatment, biomass characterization and process optimization. WP3: ChCl:Gly recycling by applying anti-solvent treatment method. WP4: Lignin recovery and conversion into bio-oil via fast-pyrolysis. WP5: Enzymatic hydrolysis and process optimization. WP6: Studies on microbial stress (osmotic, ethanol and temperature) tolerance by employing flow cytometry, selection of well adapted yeast strains and fermentation. WP7: Techno-economic analysis based on the conceptual model of a cellulosic ethanol plant. Expected outcomes are: The technological development will create industrially accessible zero-waste strategy that can be adopted for the processing of other biomass feedstock (e.g. municipal solid waste and forestry residues). The competition between food and fuel will be avoided, thus protecting the global food security. It will also help to decrease CO2 emissions and combat global warming. This project is well aligned with the European Union biofuels support policy, aimed at lowering CO2 emissions in the transport sector.

木质纤维素生物量（LCB）是一种可持续的能源，可生产生物燃料和生物基化学物质，而不会影响全球粮食安全。 LCB的顽固性质阻碍了酶水解，因此预处理是关键的一步。胆碱氯化物：甘油（CHCL：GLY）是LCB脱节的有前途的溶剂。该项目的创新方面由微波辅助的CHCL：GLY预处理组成，以划定稻草的结合，并连续培养热带念珠菌和酿酒酵母将糖发酵到乙醇中，以开发零废物生物货币。该项目由七个研究目标组成，总体目的是培训该研究员的学术专业知识，专业技能和多学科合作。项目活动分为七个工作包（WPS）。 WP1：获得总体培训和知识间交易。 WP2：原材料预处理，预处理，生物质表征和过程优化。 WP3：CHCL：通过应用抗溶剂治疗方法进行GLY回收。 WP4：木质素恢复并通过快速热解转化为生物油。 WP5：酶水解和过程优化。 WP6：通过使用流式细胞术，适应良好的酵母菌菌株和发酵的微生物应激（渗透，乙醇和温度）耐受性的研究。 WP7：基于纤维素乙醇植物的概念模型的技术经济分析。预期的结果是：技术开发将创建可用于处理其他生物质原料（例如，市政固体废物和林业残留物）的工业可及的零废物策略。将避免食品和燃料之间的竞争，从而保护全球粮食安全。这也将有助于减少二氧化碳排放并打击全球变暖。该项目与欧盟生物燃料支持政策非常一致，旨在降低运输部门的二氧化碳排放。
