Altri, leader in sustainable cellulosic pulp production, has signed an agreement to acquire a majority stake in AeoniQ – marking a decisive leap into sustainable textiles. The Altri investment, including a capital increase, will allow building out commercial-scale AeoniQ production capacity, reinforcing its strategic vision to diversify into high-value, low-impact cellulosic applications.
AeoniQ, a Swiss-based cleantech spin-off of HeiQ Materials AG, has developed the world’s first climate-positive, biodegradable cellulosic filament yarn engineered to replace polyester and nylon. The AeoniQ platform is poised to disrupt the global textile industry by offering a fully circular, plastic-free alternative that mirrors the performance of synthetic fibers – without their environmental toll.
As part of the agreement, the world’s first industrial AeoniQ plant will be constructed at Altri’s Caima pulp mill. Construction is expected to begin in 2026 with an initial capacity of 1,750 tons per year. On top of the already existing pilot lines in Austria, a pre-industrial plant will be launched in 2026 in Portugal to accelerate prototyping, brand partnerships, and capsule collections.
The completion of the acquisition is subject to the fulfilment of closing conditions, as is standard in transactions of this nature. The companies expect the process to be completed in Q3.
Altri is a leading European company in the production of eucalyptus fibers, sustainable forest management and renewable energy production.
