Hydro announced Alunorte has issued a force majeure notice following orders from federal, state and local authorities to cut alumina production by 50 per cent. Alunorte has also declared force majeure due to lack of clarity into what measures it would take to return Alunorte to normal operations.

“Contingency plans are being implemented, and Alunorte is doing its utmost to reduce the potential negative effect on customers and suppliers. Hydro, as the largest offtaker of alumina from Alunorte, is taking and assessing a range of possible mitigating actions to minimize the negative effect for its customers,” Hydro said.
“The force majeure notice comes after a period of extraordinary rainfall led to flooding in Barcarena, where Alunorte is situated. Due to concerns over possible water contamination from Alunorte during this flooding, authorities have taken several measures against the alumina refinery, including orders to cut alumina production and halt operations at its DRS2 bauxite residue deposit.”
Alunorte is the world’s largest alumina refinery, and has a nameplate capacity of an annual 6.3 million tonnes. On average, 14 per cent of its production goes to the domestic market and the other 86% is exported.
