In fact, many materials used to make solar panels can still be recycled. For example, the core material crystalline silicon can be reused in the heavy metal industry, glass panels can be sent to the glass manufacturing industry, and aluminum frames can be sent to aluminum refineries. After the cables and connectors are crushed, they can be reused in the form of copper beads, and waste plastics can be used as fuel... So as long as they are handled properly, there is no need to worry too much about the impact on the environment after the solar panels are scrapped. Bring new pollution, or cause waste of resources, so how should we deal with the scrapped solar panels?
The first is to strengthen the research on the recycling and processing technology of waste photovoltaic modules. Increase research on recycling technologies for new types of components, such as flexible components, MWT components (involving the recycling of components without solder strips), and heterojunction components (involving the recycling of indium compounds).
The second is to strengthen the research on recycling and processing technology of production raw materials. In addition to the recycling of waste components, in the production process of photovoltaic products, a certain proportion of materials such as film, backplane, frame, glass, etc. will also be scrapped. It is also necessary to strengthen the research on the recycling and processing technology of scrap materials.
The third is to improve the green development level of recycling work. Promote energy saving and consumption reduction and green emission reduction in the industrialized treatment of waste components, and realize harmless treatment. The fourth is to strengthen the green design of photovoltaic products. From the material selection and product design side, consider the follow-up recycling issues, such as developing packaging materials that are more conducive to the separation of film, backplane, glass, etc., developing and promoting flexible component products (there is no problem of glass and frame recycling), etc.
