Global demand brought by the rapid technological growth and increasing industrial population has led industries to increase production to meet the demands of consumers and maximize profit by opting to use more plastic packaging due to its cheap and convenient nature. Plastic can be made quickly and in large quantities, supporting fast- paced manufacturing. To improve product strength and appearance, many industries use polymer-laminated aluminum packaging (PLAP). However, PLAP is hard to recycle and often ends up as waste, causing environmental problems. Environmental concerns have inspired recycling efforts, like turning from cans and foils into valuable materials such as aluminum formate and aluminum-based products like cosmetic products and pigments. Given the high demand for aluminum hydroxide (AH) for its antacid properties, wastewater treatment and its use in research as a reactant, this study focuses on recycling aluminum from PLAP into AH, aiming to make packaging more sustainable. This research utilized PLAP from Kopiko coffee products. The transformation method involved an alkali process where aluminum was recovered as sodium aluminate, which was then used to produce AH. The PLAP and AH produced were characterized using SEM-EDS to determine their crystallographic and elemental compositions. The PLAP exhibited a smooth surface with high aluminum content, while the AH showed a crystallographic structure similar to commercially available AH. Although EDS could not detect hydrogen, it confirmed the presence of aluminum and oxides (specifically Al;O:). The synthesized aluminum hydroxide contained a high amount of oxygen and aluminum of 17.08% and 55.52%, respectively, despite having a relatively low aluminum percent recovery of 35.20%o. Therefore, the synthesis of aluminum hydroxide from the aluminum layer of a PLAP offers a valuable opportunity to recycle aluminum and provides a new avenue for the valorization of single-use plastic-aluminum packaging.
