Use advice for data set When using the LCA data for the described chemical treatment process, ensure that it is applied to scenarios involving the recycling of Al, Ag, and Si in the context of PV module manufacturing. Use the data in line with environmental impact assessments and industry reports for the polysilicon and PV sectors in China. If multiple data sources provide inventory information for the same material, utilize the average values to align with the methodological framework outlined in the described process. The inventory data sets should be regularly updated to reflect the latest industry practices and input from multiple photovoltaic enterprises.

General comment The remaining silicon metal and the other dissolved metals in theacid solution are successively treated.The recycling framework is shown in Fig. 5. Glass need to be remelted, EVA (Ethylene Vinyl Acetat) need thermal treatment, and aluminum need remetling and chemical treatment before they may substitute virgin materials in the module assembling process. Meanwhile, chemical treatment is necessary for silicon and silver before recycling in polysilicon production and multi-Si PV cell respectively.

Technical purpose The described process involves the chemical treatment of aluminum (Al), silver (Ag), and silicon (Si) for recycling purposes. The aluminum undergoes remelting and chemical treatment to enable its use as a substitute for virgin materials during the module assembling process in photovoltaic (PV) production. Similarly, chemical treatment is essential for the recycling of silicon in polysilicon production and for silver in the manufacturing of multi-Si PV cells. This process is specifically geared towards PV industry applications, supplying recycled high-purity materials for use in solar module manufacturing.
