New insights into sustainable lignocellulosic aerogels
Yuanyuan Li, KTH Royal Institute of Technology, Sweden
With low density and high specific surface area, aerogels are attractive in various applications ranging from aerospace to thermal insulation and energy storage. The mechanical brittleness and sustainability requirements of mainstream SO2 aerogel drive the investigation of biomass-based aerogels.
Lignocellulosic materials are of increasing interest, given the carbon neutrality due to CO2 storage during biosynthesis and superior mechanical property of nanocellulose. Wood is one of the main sources of cellulose. Lignocellulosic aerogels are often obtained through a bottom-up approach, disintegrating wood into nano building blocks (e.g. nanocellulose) followed by reassembling into aerogels. The complex processing and high energy consumption are challenges. Top-down approach is an alternative by directly using wood while the nanostructured wood cell wall is in-situ modified. The step of nano building blocks extraction is eliminated which is beneficial for scalable fabrication.
In this context, wood aerogels, a highly nano porous structure with cellulosic nanofibril network filling the empty wood channels, are fabricated through cell wall partial dissolution and regeneration. The development of wood processing to achieve wood aerogels structures will be explained. The structure understanding of the aerogels will be presented. Relative applications benefit from the structural design will be demonstrated including thermal insulation and hydrovoltaic energy harvesting.

Twisted cellulose-based structures
Maria Helena Godinho, NOVA Science of School and Technology, Portugal
Cellulose, the main structural component of plants, forms twisted architectures across scales—from molecular to macro. These structures contribute to vibrant coloration, mechanical strength, and movement [1, 2]. This seminar explores twisted forms in cellulose-based systems, focusing on cellulose nanocrystals, their interaction with water, and color generation under non-equilibrium conditions. Examples at the micro and millimetre scales, such as leaf petioles [3] and Erodium fruit awns [1, 2], illustrate diverse helicities and adaptive behaviours. The findings highlight opportunities in out-of-equilibrium systems and the potential of bioinspired materials with unique optical and mechanical functions.

From biomass to functional polymer composites– the role of nanocellulose
Gilberto Siqueira, EMPA, Switzerland
The Cellulose & Wood Materials laboratory at Empa has over 20 years of experience in producing nanocelluloses (CNC and CNF) from a wide range of biomass sources, including wood, wheat straw, recycled newspaper, algae, bacterial cellulose, and food residues such as carrot, broccoli, apple peel, and brewery spent grains.
These nanocelluloses have been explored for applications in packaging, polymer reinforcement, biomedical scaffolds, and for the preparation of inks used in 3D printing of functional materials, such as sensors.
To enable 3D printing of nanocellulose-based composites, we have developed several strategies that allow the homogeneous dispersion of nanocelluloses into various polymer matrices, including polyhydroxyalkanoates, silicone, sodium alginate, hyaluronic acid, and pluronic, among others.
The ability to homogeneously disperse high concentrations of nanocellulose in these inks enables precise tuning of rheological properties and reinforces the printed structures without the need for additional rheological modifiers.
Among the functional materials developed by our group, we highlight the creation of a 3D printing platform for fabricating fully 3D-printed soft electronic devices, such as shoe insoles, for health monitoring. Additionally, we have encapsulated microalgae (e.g., diatoms and dinoflagellates) to develop engineered living materials for sensing water quality, as well as mechanoluminescent living objects for potential applications in soft robotics.

Lithium-ion batteries (LIBs) are a key enabling technology for the electrification of transport and the transition to renewable energy systems. However, their large-scale production and end-of-life management raise significant environmental and social concerns. This lecture explores strategies to enhance the sustainability of LIBs across their life cycle, from raw material selection to recycling and second life.
We will begin by examining the environmental impact of critical materials such as cobalt, nickel, and lithium, and the need to develop alternative chemistries and components with lower environmental footprints. Particular attention will be given to the use of bio-based and biodegradable polymers, such as lignin and cellulose derivatives, for electrodes, binders, and separators—highlighting recent advances and their integration into scalable battery designs.
The session will also cover sustainable process innovations within gigafactories, including solvent-free electrode manufacturing, water-based formulations, and energy-efficient drying techniques. Finally, we will address circular economy approaches such as direct recycling, materials recovery, and repurposing of end-of-life cells in second-life applications.
Through case studies and recent research findings, participants will gain a comprehensive understanding of how materials science, green chemistry, and process engineering converge to enable next-generation sustainable energy storage solutions.
