[SMM Aluminum Express News] Alcoa menghadapi tekanan regulasi di kilang alumina Wagerup miliknya di Australia Barat, yang menyoroti risiko terhadap pasokan aluminium hulu. Emisi merkuri yang terkait langsung dengan pemurnian bauksit hampir meningkat dua kali lipat sejak 2022 menjadi ~400 kg pada 2025, didorong oleh peningkatan produksi alumina, kualitas bijih, dan masalah peralatan. Meskipun regulator menyatakan emisi masih dalam batas yang dapat diterima, kelompok lingkungan telah mengajukan banding terhadap izin operasi kilang tersebut, sehingga meningkatkan risiko pengetatan kondisi operasional bagi aset alumina utama ini.
