Over the last decade, rare earth elements (REEs) have gained international attention due to their multiple usages. Because of their unique properties, the elements play a vital role in electronics, defense, aerospace, transportation, agriculture, and communications technology. They are also critical to the high technology and low carbon economy. These applications drive demand for rare earth products and promote the steady development of the rare earth industry. In this paper, we have reviewed the current scenario, applications, challenges, and impacts of REEs from a global perspective. It is seen that China leads in the production of REEs worldwide. Globally, REE production is associated with a range of environmental issues, including mining-related pollution, the generation of radioactive waste, water scarcity, soil contamination, and deforestation, all of which impact both humans and animals. Drawing from global literature, we discussed a comparative scenario of REEs in Bangladesh. In Bangladesh, the rising population has led to increased REE demand, and we utilized secondary sources to deduce REE impacts. We overviewed aspects such as 100% electricity coverage, import opportunities from the other countries, and government initiatives, all contributing to the growing REE demand and e-waste generation in Bangladesh. Currently, there is no recycling process available. Subsequently, we highlighted the situation in Bangladesh regarding REE management, presented suggestions for recycling based on recent global literature, and provided recommendations for the future.
