A team of researchers has found that volcanic materials from Mount Semeru contain promising amounts of europium (Eu), a rare earth element widely used in green energy technologies and modern industries. This discovery highlights Indonesia’s potential to contribute to sustainable energy and economic growth while supporting global efforts to tackle climate change.
Rare earth elements, like europium, play a crucial role in the production of renewable energy systems, such as wind turbines, electric vehicles, and high-efficiency lighting. By exploring natural sources of these minerals, researchers aim to reduce greenhouse gas emissions, diversify energy resources, and open up new opportunities for economic development.
In this study, volcanic ash, sand, and andesite rocks were collected from four locations around Mount Semeru. Using advanced laboratory techniques, the researchers measured europium content and magnetic susceptibility to determine the quality of the mineral deposits. Results showed that europium levels in the samples ranged between 0.2% and 0.49%, with an average of 0.37%. Moreover, the study confirmed that magnetic susceptibility can serve as a reliable indicator of europium content in volcanic materials.
The findings are more than just numbers—they point to significant benefits aligned with the United Nations Sustainable Development Goals (SDGs):
- SDG 7 (Affordable and Clean Energy): By providing key materials for renewable technologies, europium supports the transition to clean energy.
- SDG 8 (Decent Work and Economic Growth): Sustainable mineral utilization could create new jobs and boost economic diversification.
- SDG 9 (Industry, Innovation, and Infrastructure): Research like this encourages innovation in resource exploration and green industry.
- SDG 13 (Climate Action): Using locally sourced materials for clean energy helps reduce reliance on fossil fuels and lowers carbon emissions.
Mount Semeru’s volcanic legacy, often seen as a natural hazard, may also hold the key to a greener and more sustainable future. With responsible exploration and management, Indonesia could strengthen its role in the global clean energy transition.
