Value Chain Analysis

The isosorbide value chain starts with carbohydrate feedstocks (corn, wheat, sugarcane, and other sugars), followed by hydrolysis to glucose and hydrogenation to sorbitol. From there, isosorbide is produced through acid-catalyzed dehydration of sorbitol, then further purified to polymer-grade and pharmaceutical-grade specifications for sale to resin producers, compounders, and pharmaceutical manufacturers.

Control points across the chain cluster around sorbitol availability, dehydration reactor design, and purification economics. Producers with integrated starch-to-polyol assets and established dehydration capacity, such as Roquette (POLYSORB isosorbide, anchored by its Lestrem, France operations), can maintain more consistent input quality and reduce logistics exposure. On the technology side, the supply chain continues moving away from mineral acids toward heterogeneous solid acid catalysts and continuous-flow processing, supporting higher selectivity, improved safety, and high-purity output for performance polymer (including optical-grade polycarbonate) and regulated pharmaceutical uses.
