Selective hemicellulose hydrolysis of Scots pine sawdust

Abstract: The depletion of fossil resources is driving forward the search for new and alternative renewable feedstocks in the production of renewable chemicals, which could replace the petroleum-based ones. One such feedstock is pine (Pinus sylvestris) sawdust, which is generated enormous amounts in Finnish sawmills yearly. However, prior to the utilization in high-value applications, it needs to be fractionated into its constituents. In this work, the objective was to produce monomeric hemicellulose sugars from pine sa… Show more

“…Similarly, to other biomass residues, the pinewood sawdust consists not only of lignin but also of cellulose, hemicellulose, pectins, sugars and other minor compounds [ 29 , 37 ]. Often, during the fractionation process, the extracted lignin is contaminated with other compounds, particularly if the method used is poorly selective.…”

“…Hemicellulose and cellulose structural polysaccharides can be hydrolyzed into valuable products of monomeric sugar mixture units and be further converted into platform chemicals [ 22 , 23 ]. Chemical process has impact on the end-product quality [ 22 , 23 ], but also raw material characteristics determine its usability in various chemical applications.…”

“…As the extraction conditions are determinant for a successful fractionation process, it was intended to initially study the effect of the extraction time and temperature on the extraction yield, by systematically varying these two parameters for a fixed LA:FA solvent ratio of 1:1 (v/v) ( Figure 2). Two striking observations can be made from the analysis of Similarly, to other biomass residues, the pinewood sawdust consists not only of lignin but also of cellulose, hemicellulose, pectins, sugars and other minor compounds [28,35]. Often, during the fractionation process, the extracted lignin is contaminated with other compounds, particularly if the method used is poorly selective.…”
