Correction: Bandarra et al. A Study on the Classification of a Mirror Entry in the European List of Waste: Incineration Bottom Ash from Municipal Solid Waste. Sustainability 2022, 14, 10352

The authors would like to make the following corrections to the published paper [1]. The changes are as follows:

Council Regulation (EU) 2017/997 was followed when evaluating the ecotoxicity of IBA (samples A4–A6) from a chemical point of view. According to Annex VI of CLP, Zn dust is classified into Aquatic Acute Toxicity Category 1 and Aquatic Chronic Toxicity Category 1. Considering the “worst-case scenario”, some of the compounds that could be found are ZnO, ZnSO₄ or zinc chloride, which are all classified as Aquatic Acute Toxicity 1 and Aquatic Chronic Toxicity 1. For copper, one could find CuO and copper (I) oxide, both also classified with Aquatic Acute Toxicity 1 and Aquatic Chronic Toxicity 1. Lead compounds not specified elsewhere in Annex VI of CLP are also classified as Aquatic Acute Toxicity Category 1 and Aquatic Chronic Toxicity Category 1. The limit value of 25% for the sum of all the substances present in IBA classified as toxic to the aquatic environment was exceeded, according to the calculation formulas from Council Regulation (EU) 2017/997. Nevertheless, Commission Decision 2014/955/UE indicates that when a hazardous property has been assessed via a test and using the concentrations of hazardous substances, the results of the test shall prevail. The possible combined effect of the substances was verified through an ecotoxicity test with Daphnia magna. An EC₅₀ value > 160,000 mg/L was obtained via the test. Regulation (EC) 1272/2008 establishes that EC₅₀ < 100 mg/L demonstrates ecotoxicity. Thus, the results of the test indicate low acute toxicity for the environment, and the waste was not classified with HP 14 for any of the samples.
