Altri SGPS S.A. is a European producer of cellulosic fibers, headquartered in Porto, Portugal. The company's core business model revolves around the production and sale of bleached eucalyptus kraft pulp (BEKP) and dissolving wood pulp (DWP), which serve as essential raw materials for the manufacturing of tissue, printing and writing papers, and textiles. Altri operates three pulp mills in Portugal—Celbi, Caima, and Celtejo—which are supplied by the company's managed eucalyptus forests.
Pulp sales are the primary driver of the business, accounting for approximately 81% of total revenues. The remaining revenue is largely generated from its renewable energy segment, where the company utilizes forest biomass and black liquor, a byproduct of the pulping process, for industrial cogeneration and electricity production.
Geographically, Altri exports the vast majority of its products. Europe is its largest market, typically accounting for over 60% of sales, followed by the Middle East, North Africa, and Asia. The company's competitive position is supported by its vertically integrated operations, linking forest management directly to pulp and energy production. This integration ensures a stable supply of raw materials and operational efficiency. Altri also engages in complementary activities such as timber commercialization, real estate, and plant nursery operations, though these remain a minor part of the overall business.
