In the journey of exploring natural resources, germanium, an element that plays an important role in the high-tech field, has undoubtedly become the focus of our attention in terms of waste recycling and reuse. The source of germanium waste is like a complex network covering multiple high-tech industries, among which the semiconductor industry is undoubtedly the "big fish" in this network.

The semiconductor industry, as the cornerstone of modern electronic technology, is the main "export destination" for germanium waste. Here, high-end materials such as polycrystalline silicon germanium and monocrystalline silicon germanium may generate waste containing germanium at every stage of production, processing, transportation, storage, and even recycling. Especially polycrystalline silicon germanium, due to its wide application and large-scale production, occupies the vast majority of germanium waste. The residual germanium in these waste materials, although seemingly insignificant, actually contains enormous value.

However, the sources of germanium waste are far more than that. In the production process of high-speed rail germanium alloy, a certain amount of germanium waste will also be generated. These alloys have a wide range of applications in aerospace, high-speed railway and other fields due to their unique physical and chemical properties, and germanium, as a key component, has significant importance in the recycling of waste materials.

In addition, industries such as high-efficiency glass, optical optoelectronics, and solar cells are also important sources of germanium waste. With the rapid development of these industries, the demand for germanium is constantly increasing, and the amount of germanium waste generated during the production process is also increasing. If the germanium in these waste materials can be effectively recycled and reused, it will have a positive impact on alleviating germanium resource shortages, reducing production costs, and promoting sustainable development.

It is worth mentioning that the current recycling value of pure germanium is quite considerable. According to the latest market trend, the recycling price of pure germanium has exceeded the threshold of tens of thousands of yuan per kilogram. This price not only reflects the scarcity and importance of germanium resources, but also reflects the high recognition of the market for the recycling and reuse of germanium waste.
