The transition from a fossil-based economy to a circular bioeconomy is a critical challenge and opportunity in the face of global climate change. Sweden and Finland, with their abundant forest resources and strong commitment to sustainability, are well positioned to lead this transition. The WoodPro project exemplifies this effort by exploring innovative ways to valorize forest residues into high-value products such as 2,3-butanediol (2,3-BDO), biopolymers and hydrochar. This perspective outlines the project's multidisciplinary approach, which integrates advanced bioprocessing technologies with dynamic system analysis to optimize the sustainability and economic feasibility of these biorefining pathways. We highlight the potential of these interconnected processes to reduce greenhouse gas emissions, close nutrient loops and stimulate rural development, while positioning the Nordic countries as global leaders in the circular bioeconomy. The insights gained from this project highlight the importance of holistic, systems-based approaches in achieving carbon neutrality and offer a model for similar transitions worldwide.

The concept of the circular bioeconomy is a carbon neutral, sustainable system with zero waste. One vision for such an economy is based upon lignocellulosic biomass. This lignocellulosic circular bioeconomy requires CO absorption from biomass growth and the efficient deconstruction of recalcitrant biomass into solubilized and fractionated biopolymers which are then used as precursors for the sustainable production of high-quality liquid fuels, chemical bioproducts and bio-based materials.

Electrotechnology has recently emerged as an eco-friendly method for enhancing microalgal processes. Electric fields can be applied to microalgae at different stages to improve their biomass productivity, high-value products (HVPs) content, harvesting efficiency, and cell disruption for biomolecule recovery. Incorporating them into microalgal processes can significantly contribute to achieving a circular bioeconomy.

Colloidal Lignin Particles (CLPs), with their polyphenolic structure, are promising sustainable alternatives to chemical UV filters. This study investigates the photochemical behavior of CLPs under ultraviolet irradiation synthetized from five different technical raw lignins (Alkali, Organosolv, two Enzymatic Hydrolyzed and Softwood Kraft Lignin) via solvent-shift procedure. The suspensions were irradiated using a self-developed UV-pen set-up and a commercially available UV chamber, enabling controlled UV exposure over time.

This study investigated the valorisation of seawater desalination brine (61 g L1) by cultivating the halotolerant microalga Prymnesium parvum in 10-L bubble column photobioreactors, previously acclimated to a broad salinity range (5-61 g L1). Under optimized nutrients and irradiance, brine-based cultures achieved biomass yields (1.9 gL1) comparable to seawater controls.

Pomegranate processing generates large quantities of pomace and mesocarp, yet their carbohydrate composition remains largely unexplored. Here, we applied comprehensive mass spectrometry-based profiling to characterize monosaccharides, oligosaccharides, and polysaccharides from these side streams. Fructose and glucose dominated the free sugar fraction in both tissues.
