PhD fellowship in Wood Science
PhD Project in novel grass-based materials
Department of Geosciences and Natural Resource ManagementFaculty of Science
University of Copenhagen
The Department of Geosciences and Natural Resource Management invites applicants for a PhD fellowship in novel grass-based materials, focusing particularly on biobased material components (adhesives and fibres). The project is part of a larger research project called “GrassCO2mposites” on storage of biogenic carbon in the built environment by developing novel, sustainable composite materials from grassland biomass, which is financed by the Innovation Foundation Denmark strategic InnoCCUS programme.
Expected start date is November 1st, 2026 or as soon as possible thereafter.
The project
The built environment has an enormous material and energy footprint. Boosting the understanding and use of sustainable building materials and energy renovation of existing buildings is a central Danish and European priority to bring down carbon emissions.However, general and sensible energy renovation should limit the use of energy-intensive materials based on nonrenewable resources, e.g. mineral wool and plasterboards, to avoid increasing carbon emissions from material production and depletion of non-renewable resources.
Instead, grass composites are expected to be used across all building elements, from floor, ceiling, walls, spatial partitions, window casings, doors, panels, and insulation to acoustic modules.
Grassland biomass is a promising alternative:
- Renewable resources that can be cultivated and harvested multiple times each year with high dry matter yields per hectare, while reducing nutrient leaching and pesticide use, increase soil carbon and improve biodiversity in the agricultural production.
- Capture atmospheric carbon by photosynthesis and embeds it in the material structure.
- Store the carbon as long as the material is not degraded.
- Fibre composite structures enable enormous application fields, from bulk to bespoke building parts.
The hypothesis of the GrassCO2mposites project is that grass-based materials can reduce carbon emissions by substituting conventional, energy-intensive materials and boost carbon storage by creating higher value long-lived building elements in the built environment.
This PhD project is one of three PhD projects in the GrassCO2mposites: another PhD project at Aarhus University will focus on biorefinery of grass biomass for further use as building material components, while the last PhD project at the Royal Danish Academy will focus developing methods for fabricating grass-based composites for building materials and building elements with a focus on thermal performance.
This PhD project will develop novel grass-based material components (adhesives, fibres) for composite material manufacturing. Adhesives will be developed by first chemical characterization of fractionated biomolecules from grass biomass followed by functionalization and formulation of adhesives.Fibres will be characterized in terms of their chemistry and geometry, and the surface chemistry will be functionalized for improved processing and adhesion. Finally, the material properties of developed adhesives and improved fibres will be characterized and validated.
Who are we looking for?
We are looking for candidates within the field(s) of materials science, biotechnology, plant sciences, organic chemistry, wood and science technology, and chemical engineering. Previous experience with relevant biomolecules (e.g. lignin, starch, cellulose), biobased adhesives, biobased materials e.g. for construction, and biological materials science in general is seen as an advantage.Applicants should have laboratory experience, data handling skills, a collaborative approach, and be scientifically curious.
Our group and research - and what do we offer?
Our research group, Bioresource Chemistry and Technology, contributes to both fundamental and applied aspects of the sustainable utilization of biomass for materials, chemicals, and bioenergy by the creation of knowledge and development of technologies within this subject area.This includes a fundamental understanding of the chemistry and physical properties of the cell walls in plants, and how this intricate biocomposite interacts with external factors (e.g. biological agents, chemicals, catalysts, and water) during processing or use.
It also includes studies of molecular level interactions, between plant cell wall polymers and fungi, enzymes, water, and chemical reagents, as well as attention to sustainability aspects, as technologies are transferred from laboratory scale to industrial scale biomass utilization.
The group is imbedded in the section for Forest and Bioresources, and in the Department of Geosciences and Natural Resource Management, Faculty of Science, University of Copenhagen. We are located in Copenhagen. We offer creative and stimulating working conditions in dynamic and international research environment.
