The life cycle impact assessment (LCIA) results for the Indian chitosan supply chain, as published in the article, contain an error in the BWater use^indicator. While water use during chitin and chitosan manufacturing were accounted for in the inventory analysis (167 L/kg chitin and 250 L/kg chitosan, see section 3.2 in the article), these flows were not covered in the impact assessment calculations, thus leading to an underestimate of the overall water use in the supply chain. In Table 1 and Table 2 below, we provide the corrected values for water use, for both chitin and chitosan. These tables replace the corresponding data for BWater Depletion^in Tables 17 and 18, respectively, in the supplementary material, where the detailed LCIA results are reported for the Indian supply chain.In section 4.1 of the article, the text reads: BIn water use, the water saving is higher than the water use^. Similarly, in section 5, the text reads: BThe use of shrimp shells as raw material affects the market for animal feed, resulting in a credit in many impact indicators, especially in water use, where the net result is a water saving^. In both cases, the statement that producing chitosan leads to a net overall water saving does not hold true anymore after the correction, since the induced water use in the chitosan factory is higher than the water saving associated to the raw material.Below, we provide corrected versions for Figs. 3, 4, and 7. It must be highlighted that compared to the figures in the article, only the water use indicator has been subject to corrections.The online version of the original article can be found at http://dx
