This study provides a comprehensive review of recent advancements in aluminum recycling technologies using molten salt electrolysis. It critically assesses the improvements in the process, their impacts, and the industrial challenges faced during implementation. The analysis presented herein demonstrates that the electrolysis process significantly enhances the usability of recycled products. Molten salt electrolysis method is highly effective in waste treatment, enabling the processing of \"dead\" metals and secondary aluminum dross—materials typically excluded from conventional industrial practices. When recycling aluminum dross, the complexity of the dross composition and the sustainability of the recycling process need to be considered. Based on these considerations, we propose two novel strategies for aluminum dross recycling.

The recycling of photovoltaic modules is an important work in the closed-loop development of the new energy industry, and the first step of recycling is decapsulation. Hydrometallurgical decapsulation has been considered an important recovery method due to energy saving and the ability to recover all components of photovoltaic laminates. However, the problems of low decapsulation efficiency and pollutant discharge need to be solved. This article reports a new green linalool solvent employed for decapsulation. The experimental results show that the delamination rate of the glass of the laminates with particle sizes of 0.5, 1, 2, and 3 cm can all reach 100% in 4 hours. Furthermore, we propose a strategy to improve the efficiency of decapsulation by enhancing the bond-breaking tendency of the crosslinking bridge formed by the coupling agent in the EVA-glass interface. It indicates that the Lewis acid properties of Al<sup>3+</sup> and its coordination effect with nitrogen atoms promote the hydrolysis of C<img>N bonds in the amid group. The increase of decapsulation efficiency by adding Al<sup>3+</sup> increases with the decrease of laminate particle size. When the particle size is 0.5 cm and 1 cm, the efficiency is increased nearly two times.
