Innovation award “Cellulose Fibre Innovation of the Year 2025”..
1st place: SA-Dynamics (DE): Cellulose Aerogel Textiles – Next-Generation Insulation Materials
Cellulose Aerogel Textiles are revolutionary insulation materials made from 100 % biodegradable cellulose aerogel fibres. These combine the flexibility and ease of processing of traditional fabrics with the superior thermal insulation properties of aerogels by utilising a novel aerogel fibre process. Lightweight, highly efficient, and compatible with conventional textile machinery, they provide a sustainable alternative to fossil-based and animal-derived insulation materials. Fully recyclable and free from microplastic emissions, Cellulose Aerogel Textiles set a new benchmark for circular economy solutions in the textile and construction industries. Initial functional demonstrators were developed through two projects, funded by Biotexfuture and RWTH Innovation, respectively. sa-dynamics.com
2nd place: Releaf Paper France (FR): Releaf Fiber – Eco-Friendly Paper from Urban Fallen Leaves
Releaf Paper France transforms urban fallen leaves into sustainable cellulose fibres, offering an eco-friendly alternative to traditional hardwood pulp. Using proprietary low-temperature extraction, high-quality fibres with excellent paper-forming properties are isolated. With a cellulose content of 32-48 % and properties similar to hardwood, RELEAF fibres are ideal for packaging materials like corrugated paper, boxes, and bags. This innovative process, which requires minimal water and non-aggressive solvents, aligns with circular economy principles, repurposing millions of tons of urban leaf waste annually and supporting global brands in achieving sustainable packaging solutions. releaf-paper.com
3rd place: Uluu (AU): Replacing plastic in textiles with natural, seaweed-derived materials
Uluu is an Australian start-up set to replace plastics with natural polymers called PHAs. Uluu materials are made from a regenerative feedstock: farmed seaweed, thus ending reliance on fossil fuels and land crops. Uluu, in partnership with Deakin University, is developing textiles that perform like synthetic polyester but are truly biodegradable and biocompatible, thus eliminating persistent microplastic pollution in fashion. Importantly, Uluu materials are reusable, recyclable, and most importantly, compostable. They are naturally produced through a unique fermentation process that uses seaweed, saltwater microbes and seawater. Uluu pellets can be directly substituted for plastic (e.g., polyester, nylon) in existing melt spinning equipment, creating yarns that can be knitted or woven into textiles. In addition to fibre-grade pellets, Uluu is also producing other grades of pellets to replace plastics used in e.g., buttons, sunglasses, hair clips and packaging. uluu.com.au
