Scale-up of sustainable production of dialdehyde cellulose and dialcohol cellulose
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 […]
The effect of compaction parameters on the properties of high-deformable paper
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 […]
Adsorption av funktionella polymerer tillcellulosa i blekningssteget – ett sätt att utöka fibrernas egenskaper
The purpose of this proposed project is to suggest new pathways for the adsorption reactions to cellulose fibers in the bleaching step in the kraft pulp process. The long-term aim is to develop a flexible knowledge platform that can be used for designing functionalized surfaces of the cellulose fibers in the bleaching step, using by […]
Lignosulfonate composited with electronic polymers for large scale energy storage applications
A renewable resource from existing forest industry is the black liquor that mainly goes to combustion. The dominating biopolymer in black liquor is a derivative of lignin. At LiU we have shown how lignin and lignosulfonate (LS) can be used to store charge into biopolymer electrodes, and built supercapacitors/supercabatteries of such electrodes. In these electrodes, […]
Process-adapted biobased assortments through novel development of the steam explosion process
The aim of the project is to, from softwood bark, develop and provide semi-manufactured industrial commodities with the following properties: a) Low content of process-disturbing/inhibitory substances during steam pretreatment b) Enhanced enzymatic digestibility c) High density and manageable properties for storage and transport Project partners: Swedish University of Agricultural Sciences, Valmet, Bio4Energy
Biocomposites-Materials modification to increase the processabilty at high fiber content
The current application aims at facilitating a substantial increase in the content of renewable lignocellulosic fibers in fiber reinforced wood fiber polymer composites (WFPL). The target is to enable production of WFPL’s with a fiber content >> 60%. For the forest based industries, this will create new market segments within construction, automotive and industrial goods, […]
Wallenberg Wood Science Center
Wallenberg Wood Science Center is a research center with a focus on new materials from trees. The center creates knowledge and builds competence that has the potential to form the basis for an innovative and sustainable future value creation from forest raw materials. WWSC is a joint research center between KTH Royal Institute of Technology, […]
Green wood adhesives based on side-streams from the pulp industry
In this project we propose to explore the use of side-streams originating from the pulp industry as adhesive binders for wood-based materials. The proposed project, aiming at developing novel, formaldehyde-free, adhesives from renewable resources, brings together experts in polymer/adhesive/wood chemistry with experts on forest/wood products and has the ability to gain novel, fundamental knowledge while […]
