木质纤维素废物，即木材、稻草和竹子，代表了用于生产生物燃料和生物材料的丰富的碳中性可再生资源。增加这些资源的使用将减少对环境的影响，如温室气体（如二氧化碳）的排放和化石燃料的消耗，有助于创造一个可持续的环境。遗传学、生物技术、工艺化学和工程学等技术的进步导致了生物精炼的概念。为探索木质纤维素废弃物生物炼制的全过程处理方法，采用蒸汽爆破预处理、水和丙酮萃取的方法，对白色白杨废弃物中木质结构成分进行了有效分离和利用。将纤维素组分转化为纤维素纤维素（CNF），并将木质素组分用作合成环氧树脂的原料。对汽爆产物进行提取，分离出水浸出物、丙酮浸出物和综纤维素。水提取物具有高儿茶素当量，并且以丙酮提取物为原料合成固化环氧树脂。此外，该研究证实了从综纤维素获得的CNF对聚乳酸的显著增强效果。蒸汽爆破、提取和分离方法以及本研究中提出的各种转化方法沿着似乎是将木质纤维素废物转化为生态材料（即CNF、固化木质素环氧树脂等）的一些最有效和环境友好（即产生很少污染物）的方法。
Lignocellulosic waste, i.e. wood, straw, and bamboo, represents abundant carbon-neutral renewable resources that are used to produce biofuels and biomaterials. Increased use of these resources would lower environmental impacts such as the emission of greenhouse gases (e.g. carbon dioxide) and fossil fuel depletion, helping to create a sustainable environment. Advances in technologies such as genetics, biotechnology, process chemistry, and engineering are leading to the concept of biorefining. In order to develop a method for the total biorefinery processing of lignocellulosic waste, this study focused on the efficient separation and utilization of woody structural components from white poplar chopstick waste by using a steam explosion pretreatment followed by water and acetone extractions. The cellulose component was converted into cellulose nanofiber (CNF) and the lignin component was used as a raw material for the synthesis of epoxy resin. The components of the steam-exploded product were extracted and separated into water extract, acetone extract, and holocellulose. The water extract had a high catechin equivalent and the cured epoxy resin was synthesized from acetone extracted as a raw material. Furthermore, the study confirmed the significant reinforcement effect of CNF, obtained from the holocellulose, on polylactic acid. The steam explosion, extraction, and separation methods, along with various conversion processes proposed in this study, appear to be some of the most efficient and environmentally friendly (i.e. generating few pollutants) conversion methods of lignocellulosic waste into eco-materials, i.e. CNF, cured lignin epoxy resin, etc.
