Norwegian aluminum maker Norsk Hydro's Alunorte alumina refinery in Brazil made unauthorized spills of waste water last month, the company said on Sunday, more than two weeks after local authorities first began to raise questions. Authorities in late February ordered the plant, the world's largest alumina refinery, to cut output in half until it addressed concerns, leading Hydro to declare force majeure with no time set to restart production. A Brazilian government-backed research institute on Friday told Reuters it will soon publish evidence of a waste leak from Alunorte, located in the northern state of Para.
