Abstract

The authors regret to inform that a mistake was found in the Life Cycle Inventory (LCI) of the study [1]. Consequently, the identified error has implications on the results reported in the original publication. The amount of crude extract from the biorefinery needed in the film fabrication step was underestimated. More specifically, in the original article 1.223 L of crude were reported to produce 3.75 kg of bioplastic, and the corrected amount is 9.058 L for a kilogram of bioplastic. For that reason, the contribution in the Global Warming impact of the biorefinery, offshore farm and hatchery stages respectively is higher than in the original article, and the recirculation of mannitol shows lower impact compared than the base scenario. Besides these differences all other main conclusions of the study remain unchanged: the highest contributor to the global warming impact remains the film fabrication stage due to the use of glycerol; recirculation of cellulose still does not allow for impact reduction, and consistently across all scenarios the composting end-of-life option has still the lowest impact. The updated results are provided in the following.
