Recent developments done in the scope of the biorefinery concept have emerged as alternatives to remove economic obstacles, thus making production of chemicals from ligno-cellulosic feedstocks become a reality. Biomass conversions employing pretreatments of hemicellulose and lignin, and acid hydrolysis of cellulose were carried out to break the polymeric structures. The saccharide components obtained produced reaction media that could be processed into value added polyols by subsequent hydrogenations.
