Harjavalta Metal Works
The Harjavalta Metal Works in southwestern Finland is one of the most significant centers of the European non-ferrous metal industry. The site's history dates back to 1944, when Outokumpu's war-critical production facilities were relocated here from Karelia. Today, the industrial zone houses major complexes of Boliden Harjavalta, which processes copper and nickel, as well as a refinery operated by Nornickel. The plant is renowned for its highly efficient smelting processes, which recover valuable by-products such as sulfuric acid and district heat for the town. Located by the Kokemäenjoki River, the works have a stable water supply and are well-connected to the nearby ports of Pori. Harjavalta plays a key role in the battery materials value chain, giving the site new strategic importance in the era of modern electromobility. Continuous modernization of filtration systems has drastically reduced environmental impacts over the past few decades. As the region's largest employer, the facility secures local prosperity and Finland's leading technological position in metallurgy.
