PhD Project: Production of Nanocellulose & Lignin-Based Biomaterials from Woody Biomass (UrbanBio)

Woody biomass, which is rich in lignocellulosic material, represents a widely available yet underutilised resource within the bioeconomy. In Ireland and across the EU, substantial volumes of forestry residues and wood-processing by-products are either discarded or diverted to low-value energy recovery. This project aligns with the European Green Deal and Ireland’s Climate Action Plan by aiming to valorise these lignocellulosic residues into high-value bio-based materials, thereby promoting circularity and resource efficiency. The research focuses on the extraction and functionalisation of nanocellulose and lignin from woody biomass to develop innovative biomaterials for real-world applications, particularly in bio-based adhesives and water purification systems. A central innovation of this project lies in the application of advanced, environmentally friendly extraction methods, such as ultrasound-assisted extraction and subcritical water treatment, as well as other green solvent-based processes, to isolate nanocellulose and lignin fractions with tailored physicochemical properties. These techniques will be optimised for yield, structural integrity, and sustainability, ensuring minimal environmental impact in terms of chemical waste and energy consumption. The project’s downstream focus is application-oriented, targeting the formulation and validation of functional composites and material systems. Nanocellulose- and lignin-based materials will be tested in pressure-sensitive and structural adhesives, assessing bonding strength, thermal stability, and biodegradability. Simultaneously, porous and reactive matrices will be developed for contaminant adsorption and antimicrobial action in water purification setups, including membrane coatings and filter prototypes. By integrating principles of material science, green chemistry, and biorefinery engineering, this project will deliver scalable, sustainable solutions for industrial adhesives and clean water technologies.

Student Requirements for this Project Applications are invited from graduates holding a first-class or upper second-class honours degree (or equivalent) or a Master’s degree in a relevant discipline such as Polymer Chemistry, Materials Science, Chemistry, Chemical Engineering, or a related field. The ideal candidate will have a strong interest in sustainable biomaterials, biorefinery processes, and circular bioeconomy applications. Prior experience working with adhesive systems or water purification technologies using bio-based or lignocellulosic-derived materials will be an advantage. The successful applicant should be self-motivated, practically minded, and capable of working both independently and collaboratively within an interdisciplinary research team.
