On November 6, a federal court in Brazil upheld a decision by a state court that forced the world's largest alumina refinery to run at half capacity. Norsk Hydro, the owner of the refinery, was ordered to slash output by half after admitting to making unlicensed emissions of untreated water during heavy rains in February. The court also upheld a ban on the company's use of a second waste deposit area near the plant. For the full story, see https://uk.reuters.com/article/us-brazil-hydro/brazil-court-upholds-par….
