Kore Metals Sàrl is a Luxembourg-based sustainable metals company specializing in the production of high-purity silicon metal. Formerly known as Maana Green Silicon Sàrl, it was spun out from Maana Electric in 2025 and is backed by InnoEnergy.
The company employs a patent-pending molten salt electrolysis (MSE) process, using renewable electricity to convert low-value silica feedstocks like sand into silicon, eliminating coal-based carbothermal reduction. This fully electrified, low-temperature method achieves up to five times lower CO₂ emissions compared to traditional processes, while delivering higher purity and cost competitiveness.
High-purity metallurgical silicon from Kore Metals serves critical applications in the chemical industry, solar photovoltaics, semiconductors, aluminum alloys, batteries, and electronics. Operating from Foetz, Luxembourg, the firm is scaling production with a pilot line planned for 2027 to support Europe's clean energy and digital supply chains.
Also known as Maana Green Silicon Sàrl.
