Polylactic acid (PLA) is a bio-based polyester and the most utilized degradable bioplastic with its production accounting for 18.9% of the entire bioplastics industry. Its monomer, lactic acid, is currently prepared via the enzymatic fermentation of sugars, under strict temperature (< 313 K) and pH (5-7) conditions, followed by purification through subsequent esterification, distillation and hydrolysis (Fig. ). Although this approach is used by 90% of the lactic acid manufacturers, its low productivity (1-13 g L -1 h -1 ) and high production cost dictate the low annual growth rate for PLA. Perez-Ramirez and coworkers demonstrated an alternative approach where glycerol is first oxidised to dihydroxyacetone (DHA) and, in a separate batch, the DHA convert into lactic acid at 413 K and 25 bar. Glycerol electrolysis to lactic acid could potentially offer a more attractive, continuous route that avoids costs associated with the processing and purification of intermediates (Fig. ).
