ReLiF – Refolding Lignins into Formaldehyde-Free protein-lignin Adhesives

ReLiF – Refolding Lignins into Formaldehyde-Free protein-lignin Adhesives

Research theme: 1-wood components, 2-biorefinery, 3-material forming, 4-material concepts

Partner(s): Luleå tekniska universitet

Financier(s): Formas

In ReLiF, the natural properties of lignins for adhesive purposes will be fully harnessed by addressing itstendency to aggregate and self-assemble. This will be achieved by using proteins as scaffolds for lignin-proteinbasedadhesives and by exploiting organic solvents and chaotropes agents that regulate lignin and proteinsolubility and disassembly. Ensuring homogenous co-assembly will preserve the adhesive properties of bothlignin and protein until thermal activation (curing) is applied, optimizing the adhesion process.Furthermore, by controlling lignin chromophore arrangements, the project aims to improve color control,enabling visually lighter and more aesthetically appealing adhesive formulations derived from wood and lignin —an advancement over traditionally dark formulations.ReLiF also presents a solution for covalent adhesives by extracting lignin-carbohydrate complexes from Swedishagricultural by-products. These complexes will serve as precursors for naturally occurring aldehyde functionality,enabling the development of strong adhesive formulations.To further refine polymer conformational control—both for the fundamental aspects of ReLiF and for broaderbiopolymer applications—computational models will be developed in correlation with experimental data. Thisapproach bridges fundamental and applied research, positioning ReLiF at the forefront of innovation in bio-basedadhesives and material science.

Research theme: 4-material concepts

Partner(s): Billerud, Karlstads universitet, SLU

Financier(s): Formas

En säker tillgång till hållbara odlingssubstrat är en viktig förutsättning för framtidens skogsbruk. Samtidigt finns ett växande behov av alternativ till torv, vars utvinning medför betydande klimatpåverkan. Projektet RePeat – Från restströmmar till hållbara odlingssubstrat undersöker om skogsindustriella restströmmar kan användas som råvara för nya, hållbara odlingssubstrat för skogsplantor.I projektet utvärderas material som renserigrus, fiberslam och bioslam med avseende på struktur, vattenhållande förmåga, kemisk säkerhet och biologisk funktion. Målet är att identifiera material och materialkombinationer som kan ersätta eller komplettera torv utan att försämra plantornas tillväxt eller odlingsresultat.RePeat bidrar också till en mer cirkulär bioekonomi genom att skapa nya användningsområden för skogsbaserade restströmmar. Projektet kan beskrivas som ett kretslopp från skogen till skogen, där restresurser från skogsindustrin ges nytt värde och används för att stödja produktionen av framtidens skog.Projektet genomförs i samverkan mellan Billerud, Karlstads universitet och SLU och finansieras av Formas inom utlysningen Biosociety Idéprövning 2026.

Lignin-Containing Microfibrillated Cellulose: Structure–Property Insights and Prospects for Energy Storage Applications

Research theme: 1-wood components, 2-biorefinery, 4-material concepts

Partner(s): KTH

Financier(s): F Georg och G Liljenroth Stiftelse

This project focuses on the development of biobased separator materials derived from lignin-rich fibrous resources originating from Swedish forestry industries, including mechanical pulp (MP), thermomechanical pulp (TMP), and high-kappa kraft pulp. By utilizing renewable lignocellulosic materials with high lignin content, the project aims to contribute to circular and sustainable battery technologies aligned with Swedish and European sustainability strategies.

Financier(s): BioGlue-Centre, Vinnova

This project is part of the BioGlue Centre (https://www.slu.se/en/departments/forest-biomaterials-technology/bioglue-centre/), which is a co-operation between three universities and many industries aiming to have a better understanding around adhesives and bonding for wood materials in different sectors, such as furniture, construction, and packaging. This project investigates the interactions between cellulose and adhesives using surface-sensitive techniques to gain a fundamental understanding of interfacial phenomena.

Lignin based fluorescent materials

Research theme: 2-biorefinery, 3-material forming

Partner(s): KTH

Financier(s): China Scholarship Council

Systematic study of the nature of lignin fluorescence mechanisms is still lacking, i.e., the relationship between lignin’s chemical structure/supermolecular structure and fluorescence properties including emission peaks/intensity, wavelength, and lifetime. Rare work is on modulation of lignin’s fluorescence properties through chemical structure modification. Lignin-based fluorescence materials design and application need further exploration.

PHA-based iNnovative agriculTurAl Solutions to deliver bio-based ferTIlisers and plant protection produCts. Agrochemicals have doubled crop yields but have also caused negative impacts. The EU aims to reduce fertiliser losses and pesticide use by 50 % by 2030. Polymer-based delivery systems can help, but they generate plastic pollution. Agricultural plastics like mulch films and growth foams minimise agrochemical use but contribute to non-biodegradable plastic pollution. The EU-funded PHAntastic project aims to reduce agrochemical and plastic pollution by developing biodegradable polymers. Based on these polymers, it will create delivery systems (mulch films and growth foams) that contain active bioproducts and will test them on horticultural crops in Europe. The project aims to contribute to more sustainable and less impactful agriculture. CETEC Biotechnology S.L.

Development and Characterization of High-Solid Cellulose Fiber Foams

Research theme: 3-material forming

Partner(s): KTH

Financier(s): Wallenberg Wood science center

This project focuses on developing bio-based porous foams from cellulose fibers at relatively high fiber concentrations. The aim is to improve fiber dispersion stability and structural homogeneity by using cellulose nanofibrils (CNF) as a stabilizing component.The project will investigate how fiber concentration and CNF content affect the final foam structure, including porosity, shrinkage, density variations, and defect formation. Different characterization methods will be used to evaluate the structure and guide formulation optimization.In the next stage, the fiber–CNF foams will be functionalized with metal–organic frameworks (MOFs) to introduce additional properties, such as adsorption capacity.

TreeGlue: fully wood-based adhesives for sustainable wood composite

Research theme: 1-wood components, 2-biorefinery

Partner(s): Chalmers

Financier(s): Formas

This project aims to develop high-performance bio-based adhesives from lignin, a renewable and abundant biomass resource. The research focuses on developing a green and mild demethylation strategy to convert methoxy groups in lignin into phenolic hydroxyl groups. This modification is expected to significantly enhance the reactivity of lignin, thereby promoting crosslinking reactions and leading to improved bonding performance and durability. In addition, the modified lignin has great potential for the development of high-value polymeric materials.
