Foamit

What Foamit does

Foamit, operating through parent entity Foamit Oyj (listed on Nasdaq First North Growth Market Finland, formerly Partnera Oyj), is a Nordic circular-economy industrial platform that recycles glass waste into foam glass aggregate and supplies cleaned glass cullet to the glass industry. The company operates four foam glass production plants across three countries through wholly-owned subsidiaries: Uusioaines Oy (Forssa, Finland), Hasopor AB (Hammar, Sweden), and Glasopor AS with two sites in Norway (Onsøy and Skjåk). Its core proprietary process grinds recycled glass to sub-0.1 mm powder, mixes it with a foaming agent, and heats the mix to approximately 900°C, producing an aggregate that is roughly 92% air and 8% glass by volume — one-fifth the weight of conventional fill while replacing multiple construction layers (lightweight fill, frost insulation, capillary break, drainage) with a single material. Manufacturing uses up to 99% recycled glass content, with verified carbon footprint disclosure (EPD) showing 46.3 kg CO2e/m³ at the Forssa plant.

Revenue is generated through three streams: (1) Foamit foam glass aggregate (Foamit 60/30/20/10/3) sold via Finnish hardware store retailers for SMB/consumer purchases and via dedicated B2B account managers for enterprise infrastructure and building construction projects, plus direct factory pickup for bulk orders over 20 m³; (2) cleaned, color-sorted glass cullet sold to European container glass, glass wool, and float glass manufacturers (approximately half exported); (3) emerging products such as Foamit Katelaatta roof tiles and AKOwall prefabricated elements developed through partner integrations. Primary customer segments are Nordic infrastructure (roads, embankments, sports fields, pipelines) and building construction (foundations, rooftops, courtyards), with secondary demand from the glass industry for cullet raw material. The company's 2025–2028 growth strategy targets EUR 100 million in revenue while extending foam glass applications into new product areas and beyond its current Nordic footprint.

Others

• Carbonaide Oy: Finnish VTT-spinout developing CO2 utilization and sequestration technology for concrete, co-developing Foamit Katelaatta with Foamit and Rakennusbetoni. Ecosystem partner rather than direct competitor, but adjacent in low-carbon construction materials.

Broad incumbents

• Argex S.A. Portuguese/Belgian producer of expanded clay aggregate for lightweight construction applications. Provides an alternative lightweight fill material to Foamit's foam glass in construction markets across Southern Europe.
• Laterlite S.p.A. Italian manufacturer of expanded clay lightweight aggregate (Laterlite, Leca) used as lightweight fill and insulation in construction. Competes with Foamit in lightweight construction aggregate but uses clay rather than glass as feedstock.
