Tannage Résumé : The global demand for renewable and affordable feedstocks, combined with the worldwide targets for reducing carbon emissions, is the driving force behind a breakthrough in resource revolution and GreenTech innovations [1]. Owing to the vast reserves and short growing cycle, utilizing lignocellulosic biomass as an alternative to petroleum and environmentally friendly feedstock to furnish bioenergy and biomaterials is key to building a more sustainable future. Lignocellulose mainly contains three biopolymers, i.e., cellulose, hemicellulose and lignin. Over the centuries, utilization of lignocellulose has crossed its possible molecular scale ranging from 101 m, as the original matrix, to 10−10 m, as a monomeric molecule. Apart from directly using raw lignocellulose beyond the micron-grade scale (e.g., building and furnishing materials), depolymerization and structural modification can endow lignocellulose-derived molecules with smaller molecular dimensions and distinct functional groups, which can be further converted into a broad spectrum of chemicals with diverse industrial applications [2]. However, the selective production of a particular chemical or group of chemicals is very challenging due to the complex original structure of lignocellulosic biomass. Instead, mixed reaction products are produced, requiring complex and costly separation procedures to obtain specific fine chemicals with high purity. In comparison, detaining the biomass depolymerization/fractionation process at the early reaction stages offers new cost-effective opportunities. Notably, utilizing the mixed oligomers with widely distributed molecular sizes produced during partial biomass depolymerization eliminates the separation/purification stages and can be considered one of the most promising opportunities for lignocellulose biorefining at the industrial level. Herein, we discuss the recent applications of oligosaccharide derivatives from lignocellulosic biomass as a mixture for green leather tanning.
