Environmental protection at the Pori site

The Aurubis Finland production site is located in the western part of Finland in the town of Pori next to the Kokemäenjoki River. The copper foundry and rolling mill are in a copper industrial park along with other companies that work with copper. The site comprises an area of about 78,000 m².

The rolling mill in Pori with 325 employees is a state-of-the-art hot and cold rolling mill, and it is fully integrated from casting to finishing. In 2025, we produced around 50,000 t of strip, sheet, plate and circles as well as around 60,000 t of shapes, more than half of which for internal use. The selection of high-quality products covers a wide range of copper and copper alloys. Copper scrap is the main input for production, and recycling materials account for around 65 % of the raw materials used in the foundry. In 2025 Pori started to use totally CO2 free electricity, and we installed an own solar power plant as one source of electricity. The waste heat that arises in the foundry is sold to local power plant Pori Energia. The waste heat produced when heating the cakes during the hot rolling process in the walking beam furnace is reused to preheat the incoming combustion air for the furnace. The excess waste heat is collected in waste heat batteries for later heating use. Emissions of dust and volatile organic compounds (VOCs) are reduced to a minimum using afterburning and filters in the foundry. Cooling water in the smelting process circulates in a closed system. Cooling and process water from the rolling mill is treated by an external service company, including the removal of copper and oil residues. In 2025, around € 180,000 was invested in measures to improve our environmental performance.
