Retraction to: Durability Enhancement of Sustainable Concrete Composites Comprising Waste Metalized Film Food Packaging Fibers and Palm Oil Fuel Ash (Sustainability, (2022), 14, 9, (5253), 10.3390/su14095253)

The Journal retracts the article “Durability Enhancement of Sustainable Concrete Composites Comprising Waste Metalized Film Food Packaging Fibers and Palm Oil Fuel Ash” [1] cited above. Following publication, concerns were raised to the Editorial Office relating to overlapping images and the overall validity of this study’s results. Adhering to our complaint procedure, an investigation was conducted by the Editorial Office and Editorial Board that confirmed the overlap between Figure 11 [1] and figures previously published in [2,3]. While the authors cooperated with the Editorial Office during the investigation, they were unable to satisfactorily explain the overlap of figures. Consequently, the Editorial Board and Editor-in-Chief were unable to confirm the reliability of the findings and subsequently decided to retract this paper. This retraction was approved by the Editor-in-Chief of the journal Sustainability. The authors did not agree to this retraction.
