Altri acquires majority stake in fibre specialist AeoniQ

Acquisition enables scaling of the world’s first industrial production of climate-positive textile yarn.
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.
