What Liasa does
LIASA (Ligas de Alumínio S.A.) is a privately held Brazilian metallurgical company founded in 1966 by José Patrus de Sousa in Pirapora, Minas Gerais, and is the largest silicon metal manufacturer in South America. The company produces silicon metal, ferro silicon, and silica fume using submerged arc electric furnaces operating above 3,000°C, with a proprietary process that pioneered the use of charcoal as a bioreducer — a method now central to its 'Green Silicon' ESG-branded product line launched in 2022. The company holds more than 16 industrial patents across processing, mechanical engineering, and electrical systems filed with Brazil's INPI.
LIASA operates a vertically integrated group structure spanning silicon metal manufacturing (LIASA), forestry and bioreducer supply (LIASA Florestas), energy trading (COMEL), stakes in three solar energy complexes providing near-100% renewable electricity, and a North American sales subsidiary (LNA). It serves industrial customers across aluminum, silicone, polysilicone, semiconductor, electronics, solar/photovoltaic, and EV battery end-markets on every continent, with primary manufacturing in Pirapora and administrative headquarters in Belo Horizonte. The company is privately held with 501-1,000 employees and has not disclosed external investors, funding rounds, or revenue figures. Revenue derives from one-time B2B sales contracts of industrial silicon products at negotiated pricing, with no subscription or recurring software-style monetization model.
