| Abstract [eng] |
this study explored delamination options for multilayer aluminum-based food packaging to enhance its recyclability. Three delamination solutions were employed: nitric acid, lactic acid, and a lactic acid and choline chloride combination. Results indicated that nitric acid effectively separated layers but caused aluminum dissolution issues. Lactic acid, alone or with choline chloride, showed promise in disassembling aluminum components. However, the polymer layers remained interconnected, and a stubborn saturated residue presented purification challenges. Nitric acid, despite a saturated residue, offered more efficient purification due to its higher water solubility. These findings emphasize the complexity of delaminating such materials and the need for further research to develop effective recycling methods while addressing residue challenges, contributing to sustainable packaging practices. |
