The project is a collaboration between Chalmers, KTH, BillerudKorsnäs and TetraPak. The aim of the project is to develop a closed or semi-closed techno-economical feasible process for production of Dialdehyde cellulose, DAC and its derivatives with a target to replace plastic materials in different applications such as thermoforming, extrusion and moulding. The project will have

Nanocellulose in the form of fibrils (CNF) from wood is a new building-block for complex nanocomposites. Both the new materials and CNF itself are of major scientific and technical interest, with strong industrial potential. The use of colloidal systems makes it possible to mix CNF with for instance montmorillonite clay (MTM) or graphene oxide (GO)

This project addresses the challenges of producing high-deformable paper for 3D forming applications using the in-plane compaction process. Enabling 3D forming of advanced paper structures paves the way for complete elimination of plastic based packaging or partial replacement of plastic in multi-material packages, which aligns with current international strategies for a sustainable development of the

Projektets mål är karakterisering och kvantifiering av deformations- och skademekanismer i kartong under komplexa belastningsfall. Sådana är praktiskta viktiga vid konvertering av kartong i allmänhet, men speciellt betydelsefulla vid 3D-formning av geometriskt avancerade strukturer. För att nå målet ska experimentella 4D datortomografiundersökningar kombineras med matematisk modellering.
This project is focused on SAXS measurements to study structuring of fibrilar systems under flow, such as 3D printing, electro spinning and fibre spinning. The project is in the framework of the feasibility study on the ForMAX beamline at MAX IV. Controlled alignment of for example cellulose nanofibrils is of high interest, since their mechanical

Layer-by-layer coating technique has been shown their considerable advantages including fast and mild process, flexibility and easy to scale up comes to the surface functionalizations. One of the most pronounced functionalities is the antimicrobial approach. We are aiming at developing non-complicated methods for antibacterial properties on different substrates mainly cellulose-based materials using alternative cationic polyelectrolytes,
The project focuses on synthetic pathways to modify lignin to introduce chemical groups suitable for cross-linking reactions and elaboration on the mechanical properties of the formed materials. The main focus is allylation, introducing an allyl ether functionallity selectively on phenols, and thiol-ene reactions for cross-linking of the thermoset resin. This is performed on technical lignin
