Germanium, this rare and precious metal element, plays a pivotal role in numerous high-tech fields due to its unique physical and chemical properties. However, the limited reserves of germanium and its uneven distribution globally have made the protection and rational utilization of germanium resources a pressing issue that needs to be addressed. In the face of this challenge, the recycling of germanium-containing waste is particularly important. It is not only an effective way to conserve germanium resources and extend their service life but also a crucial measure to reduce environmental pollution and protect the ecological environment.Firstly, from the perspective of resource conservation, the recycling of germanium-containing waste is of great significance in alleviating the shortage of germanium resources. Due to the limited reserves and the difficulty of mining germanium, recycling germanium from waste electronic products, photovoltaic cells, and other germanium-containing waste can achieve the circular utilization of resources, reducing the demand for mining new germanium ore, thereby effectively protecting the limited germanium resources. At the same time, recycling can extend the service life of germanium, allowing it to contribute to economic and social development for a longer period.Secondly, the recycling of germanium-containing waste has far-reaching significance for environmental protection. If these wastes are not recycled, the harmful substances they contain may seep into the soil, contaminate water sources, and even pollute the air, posing a serious threat to the ecological environment. However, through recycling, these harmful substances can be treated harmlessly or utilized as resources, thereby reducing environmental pollution and protecting the ecological environment we depend on. This is not only the protection of the current environment but also a manifestation of responsibility towards future generations.In addition, the recycling of germanium-containing waste also brings certain economic benefits. Due to the relatively high price of germanium, recycling these wastes can yield considerable economic returns. Market data shows that the recycling value of germanium waste is usually around ten thousand yuan per kilogram, which is of great significance for reducing production costs and improving corporate economic benefits. Therefore, more and more companies are beginning to pay attention to and engage in the recycling of germanium waste, aiming to achieve a win-win situation in terms of both economic and environmental benefits.
