Foamit Corporation (formerly Partnera Oy) is a Nordic industrial circular economy group specializing in foam glass production and glass recycling. The company, founded in 1882 and headquartered in Oulu, Finland, transforms recycled glass side streams into high-quality foam glass products for construction and infrastructure applications, as well as glass fractions for the packaging and other industries; its core operations are conducted through wholly-owned subsidiary Foamit Group Oy, encompassing Uusioaines Oy in Finland, Hasopor AB in Sweden, and Glasopor AS in Norway, forming one of Europe's leading foam glass producers. Foamit Corporation maintains a minority stake in Nordic Option, a capital investment fund targeting growth-stage companies primarily in Northern Finland, and operates across Finland, Sweden, and Norway with a focus on sustainable development, recycled raw materials, and material technologies. In June 2025, the company acquired the remaining 0.8% stake in Foamit Group Oy from Jarkir Oy for EUR 0.3 million, increasing its ownership to 100%; as part of a strategic transformation into an industrial player centered on foam glass and glass recycling, Foamit Corporation changed its name from Partnera Oy in October 2025.
