Polyisoprene Production From Raw Sugar Cost Analysis Polyisoprene E31b PDF Download

This report presents a cost analysis of Polylactic Acid (PLA) production starting from raw sugar. The first section of the examined processis similar to Cargill process for lactic acid production, while the second section is similar to the NatureWorks process for polymerization of lactic acid. In this process, raw sugar (sucrose) is diluted and sucrose is hydrolyzed into glucose and fructose (invert sugars). The invert sugars are then fermented to produce lactic acid. Lactic Acid recovery from the fermentation broth is done by trialkylamine solvent extraction in the presence of carbon dioxide. An 88 wt% Lactic Acid solution in water is generated and further polymerized to form Polylactic Acid.
