Cellulosic Pulp Productions

Altri acquires AeoniQ™ to accelerate sustainable textile innovation using biodegradable materials. AeoniQ™, a cleantech spin-off from HeiQ Materials AG in Switzerland, has developed the world’s first climate-positive, cellulosic filament yarn. Designed to replace polyester and nylon, this plastic-free fiber matches the performance of synthetics while offering a fully circular, eco-friendly alternative.

To scale production, Altri will build the first industrial AeoniQ™ plant at its Caima pulp mill in Portugal, with construction beginning in 2026 and an initial capacity of 1,750 tons per year. In addition, a pre-industrial plant will open in early 2026 to support prototyping, brand partnerships, and capsule collections. This new facility builds on AeoniQ™’s pilot lines in Austria and marks a major step toward reducing the textile industry's carbon footprint. Together, Altri and AeoniQ™ aim to lead the shift toward climate-conscious, next-generation fibers.
