Natural Antioxidants for the Development of Recyclable Packaging with Corrosion Inhibitors for Metal Parts

Abstract

This study explores sustainable alternatives to protect metal parts during transportation and storage in an effort to reduce the environmental impact of conventional plastic packaging. The purpose of this work is to develop and evaluate recyclable packaging with the addition of natural antioxidants to act as corrosion inhibitors to protect metal parts from corrosion and mitigate the environmental impact of conventional packaging. The effectiveness of natural antioxidants extracted from papaya seeds (Carica papaya L.) as corrosion inhibitors in recyclable packaging was evaluated. Corrosion and inhibitor efficiency tests were performed in different media (acid, neutral, and alkaline) to determine the capacity of these packages to protect metal surfaces from degradation. The results indicated that the natural antioxidants in papaya seed extract provide significant protection, especially in acidic environments, in addition to substantially reducing environmental impact. It was concluded that using natural antioxidants in recyclable packaging is a viable and promising solution for the effective protection of metals and the promotion of more sustainable industrial practices.
