The accelerating global demand for energy and materials underscores the urgency of transitioning away from fossil‑based resources toward sustainable, renewable alternatives. Biomass is abundant, diverse, and economically accessible, offering significant potential to support this shift. This research explores the valorisation of bio‑based feedstocks into bioenergy, biofuels, and high‑value bioproducts, advancing the foundations of a circular bioeconomy.

Agricultural residues and fast‑growing algae are examined as versatile sources for the production of advanced materials. Lignocellulosic biomass, rich in cellulose, hemicellulose, lignin, and polysaccharides, serves as a central substrate. To fully harness its complexity, my group employs innovative conversion and extraction strategies, including hydrothermal liquefaction, lignin‑first pyrolysis, biphasic extraction, and chemical and thermochemical recovery of polysaccharides.

These processes yield platform molecules and intermediates, such as lignin‑rich bio‑oil, and alginate, with tunable chemical and physical properties. Their subsequent modification enables the fabrication of value‑added materials, including bio‑based polyurethane foams and composite systems.

This presentation will outline integrated biomass‑valorisation pathways and highlight the sustainable materials developed through this research. By transforming undervalued biomass into functional, recyclable products, the work advances green innovation and demonstrates the long‑term potential of bio‑derived materials within circular resource systems.
