Correction: Medici et al. Safety and Health Concerns for the Users of a Playground, Built with Reused Rotor Blades from a Dismantled Wind Turbine. Sustainability 2020, 12, 3626

In a few interviews after the paper’s publication, Superuse Studios declared that it would be appropriate and relevant to specify that they commissioned the initial research from where this research paper derives and that they provided a solution regarding one of the main issues after the commissioned research and before the publication of this research paper. The authors agree with Superuse that integrating such information into the research paper is crucial to provide a comprehensive and clear overview of the project and the research process.

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

(1)

To clearly indicate that the architectural firm Superuse Studios partially commissioned this research, the authors wish to add an explanation, along with two references, in “Section 1. Introduction, Background” in Paragraph 2.

The original version was as follows:

“In summer 2009, some months after the opening of the playgrounds, the caretaker of Wikado applied an additional layer of paint onto the surfaces of the wind turbines.”

The following is the updated version:

“In summer 2009, some months after the opening of the playgrounds, the caretaker of Wikado applied an additional layer of paint onto the surfaces of the wind turbines. In 2011, Superuse Studios (at the time called 2012 Architecten), the designers of the Wikado playground asked Piero Medici to investigate a specific issue occurring uniquely on that project and help to propose a solution. The research was supervised by Césare Peeren, partner of Superuse Studios, and published in two reports [4,5].”

We have also added two references to the citation list, which will cause all references after Reference [3] to be moved down by two numbers both in the text and the References section:

5.

To clearly indicate that, before this paper’s publication, a solution was provided to one of the main playground safety issues, the authors wish to add an explanation in “Section 4. Conclusions” in Paragraph 2.

The original version was as follows:

“Even in this case, to know the exact composition and the potential danger of drops and leaches requires a chemistry laboratory analysis.”

The following is the updated version:

“Even in this case, to know the exact composition and the potential danger of drops and leaches requires a chemistry laboratory analysis. Directly after their discovery, Superuse Studios affirmed that the yellow droplets percolating from the rotor blades’ fibre-reinforced polymer material were related to primer and paint applied by the contractor. Soon after, the rotor blades were cleaned and coated with suitable primer and paint, resulting in the yellow droplets no longer appearing.”

(3)

We have also replaced the sentence in the “Funding” section. The original was as follows:

“This research received no external funding.”

The new version is as follows:

“This research was based on the initial studies, and resulting reports, conducted by Piero Medici and funded by Superuse Studios in 2011 (at the time called 2012 Architecten).”

(4)

We have also replaced the sentence in the “Acknowledgments” section, which was as follows:

“Thanks to Superuse Studios for granting access to the detailed information and the contacts of the stakeholders.”

The new version is as follows:

“The authors want to convey their special appreciation to Superuse Studios, the designers of the Wikado playground, who asked Piero Medici in 2011 to investigate a specific issue occurring uniquely on that project and help to propose a solution. The research was supervised by Césare Peeren, partner of Superuse Studios, and summarized in two reports. Superuse granted access to the detailed information contained in the reports, which were developed into this scientific paper, for which the authors are grateful.”

(5)

We have also replaced the sentence in the “Conflicts of Interest” section, which was as follows:

“Conflicts of Interest: The authors declare no conflict of interest.”

The new version is as follows:

“Conflicts of Interest: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. The authors acknowledge Superuse Studios for granting access to project reports and appreciate their collaboration, but this did not involve financial or competing interests influencing the study.”

The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
