Lactic Acid from Raw Sugar (Conventional Fermentation + Solvent Extraction)
Lactic Acid Operating Costs & Plant Construction Costs
This study provides the economics of Lactic Acid production from raw sugar using a fermentation process in Germany. This process is similar to Corbion process, in which Lactic Acid is recovered by acidification and purified by the use of a solvent.
The report provides a comprehensive study of Lactic Acid production and related Lactic Acid production cost, covering three key aspects: a complete description of the Lactic Acid production process examined; an in-depth analysis of the related Lactic Acid plant capital cost (Capex); and an evaluation of the respective Lactic Acid plant operating costs (Opex).
The Lactic Acid production process description includes a block flow diagram (BFD), an overview of the industrial site installations, detailing both the process unit and the necessary infrastructure, process consumption figures and comprehensive process flow diagrams (PFD). The Lactic Acid plant capital cost analysis breaks down the Capex by plant cost (i.e., ISBL, OSBL and Contingency); owner's cost; working capital; and costs incurred during industrial plant commissioning and start-up. The Lactic Acid plant operating costs analysis covers operating expenses, including variable costs like raw materials and utilities, and fixed costs such as maintenance, labor, and depreciation.

The process under analysis comprises three major sections: (1) Fermentation; (2) Recovery; and (3) Purification.
Fermentation. The raw sugar is mixed with water and fed to the fermenter. It undergoes a continuous bacterial anaerobic fermentation, being converted to lactic acid. Fermentation temperature is controlled by circulating cooling water through internal coils and pH is controlled by calcium carbonate solution addition, which reacts with lactic acid to form calcium lactate.
Recovery. The fermentation broth is decanted and the concentrated solids are filtered, removing mostly biomass. The aqueous solutions from the decanter and from the filter are acidified with sulfuric acid to convert calcium lactate into soluble lactic acid and calcium sulfate, which precipitates. The slurry outlet stream from the acidification vessel is fed to a belt filter for solids removal. The resulting aqueous filtrate is concentrated in an evaporator.
Purification. Concentrated lactic acid is sent to a solvent extraction system. Firstly, it is contacted with an organic extractant solution, forming two phases: a lactic acid-rich organic phase and an aqueous phase containing most of the contaminants. Then, the organic phase is washed with water to remove contaminants. Next, it is contacted with water at 80 ºC to recover the lactic acid into the aqueous phase. The resulting organic phase is washed with a sodium hydroxide solution and then with water to recover the extractant solution, while the lactic acid-rich aqueous solution is sent to an evaporator. The concentrated lactic acid stream is fed to a distillation system where light ends are removed. Heavy ends are hydrolyzed and recycled to the process, and the lactic acid is recovered as a side stream.

Polylactic Acid Production from Lactic Acid
This report presents the economics of Polylactic Acid (PLA) production from lactic acid using a melt process similar to the one proposed by NatureWorks. In this process, lactic acid is first oligomerized and then depolymerized into lactide, a cyclic dimer of lactic acid, which is then polymerized to yield PLA by ring opening polymerization. The economic analysis presented is based on a plant constructed in the USA.
