    Permit agreed for smelter revamp

    Chile’s state-run mining company Enami says that it has received an environmental permit for a new $1.7 billion copper smelter, as part of the modernization of its Hernan Videla Lira smelting facility in the northern Atacama region. The new facility will process up to 850,000 t/a of copper concentrate, and its electrolytic refinery will produce up to 240,000 t/a of copper cathodes for use in electronics, construction and renewable vehicles. Enami says that the modernisation will “ensure profitable and sustainable operations, and practically triple the capacity of the old smelter.”

    OMV takes green methanol from Kasso plant

    Green methanol has begun to be shipped to Austria's OMV from the Solar Park Kasso plant. The plant is operated by a joint venture between Mitsui & Co., Ltd, with a 49% share, and renewable energy company European Energy A/S (51%). The plant, located in Kassø, southern Denmark, was inaugurated on 13 May 2025 and is based on hydrogen derived from solar electricity from the adjacent 304 MW Kassø Solar Park, which is then combined with biogenic CO2 and distilled to 99.9% purity, suitable for combustion engines and plastics production. The plant makes 42,000 t/a of green methanol.
