How Can Green Biorefineries Support Turning Irish Green Biomass into Valuable Products? (CABR Research Work Spotlight)
Megan O’Brien, PhD Researcher at the Centre for Applied Bioscience Research (CABR), is investigating how green biorefinery systems can transform Irish biomass into high-value products that support sustainable livestock production.
Megan O’Brien’s PhD research is funded by Research Ireland and BiOrbic and is supervised by Dr Joanna Tierney (CABR, MTU), Prof James Gaffey (CircBio at CABR), Dr Joanna Przyborska (CircBio at CABR) and Dr Helena McMahon (CircBio at CABR)
A key aspect of Megan’s research work involves using pig intestinal cell culture models to evaluate the anti-inflammatory and antimicrobial potential of brown juice. By investigating the bioactive properties of these plant-derived fractions, her research aims to identify sustainable alternatives that can support pig health, particularly during the challenging weaning period.
The project has the potential to reduce reliance on veterinary medicines, improve animal welfare, lower mortality rates and contribute to more sustainable and economically viable farming systems in Ireland.
She recently presented her research at the 2026 ESAI Conference at Dundalk Institute of Technology (DkIT).
