1.Keynote – How could biorefineries integrated in the pulp industry be more sustainable ?
The sixth report of the Intergovernmental Panel on Climate Change emphasizes that the forest-based sector represents an important potential of mitigation actions in the near term, that could enable to limit part of GHG emissions and contribute to reach several Sustainable Development Goals. At the same time, climatic changes have an impact on forests growth, […]
1.Invited – Beta-irradiation (“e-beaming”) of celluloses – just physics or rather chemistry?
beta-Irradiation (“e-beaming”) or swelling in ionic liquids, either process on its own, are common pretreatments for biomass in biorefinery scenarios. A combination of both, as it occurs for instance in beta-irradiation of biomass that has been insufficiently washed and still contains traces of ionic liquids, causes covalent derivatization of the cellulose and covalent incorporation of […]
1.2 Tropical lignocellulosic biomass valorisation towards sustainable materials
Coconut agriculture is considered an economical crop that is commonly cultivated in the tropics. Annually, approximately 300 million tonnes of coconut were produced globally. The coconut husk constitutes about 40% of the entire fruit and is generally incinerated or brought to landfills, which could further emit unwanted greenhouse gases. The main composition of CH comprises […]
1.1 Pulping with Oxygen
To contribute to more sustainable pulp and paper processes, finding alternative processes to liberate the fibers from the wood matrix is crucial and urgent. Oxygen delignification has several benefits to the industry, and recently, its interest has grown exponentially. In this work, a process was developed in which oxygen was directly applied to wood chips […]
1.3 Unlocking the Potential of Biomass: Fibenol’s Integrated Approach to Sustainable Lignin and Microcrystalline Cellulose Production
The transition to a bio-based economy requires innovative technologies that maximize the value extracted from biomass while ensuring sustainability and industrial scalability. Fibenol has developed a novel fractionation technology that enables the efficient production of high-purity lignin and microcrystalline cellulose (MCC), unlocking new application possibilities across multiple industries. This presentation will explore Fibenol’s integrated approach […]
1.4 Unlocking the potential of isolated lignin and cellulose-rich residue obtained during microwave-assisted deep eutectic solvents (MW-DES) fractionation of spruce wood
Maximizing the utilization of all biomass components is essential for ensuring the long-term sustainability of biorefinery. In this presentation, we report the recent investigation of lignin properties obtained during microwave-assisted deep eutectic solvents (MW-DES) fractionation from spruce heartwood (HW) and sapwood (SW) before and after preliminary hot water extraction (HWE), i.e. from residue heartwood (RHW) […]
1.5 Are Wood-Origin Stilbenes Fiberline Hackers or Valuable Bio-ingredients?
The native-form wood extractives have been well understood for decades [1], however knowledge is limited only before entering the fiberline, there has not been enough scientific data to investigate the reaction mechanism behind the secondary-form wood extractives as part of the fiberline process. Extractives are highly reactive and can undergo various reactions during pulping and […]
P1.1 – Unravelling fungal enzymatic degradation strategies for spruce wood in biorefinery applications
By 2050, global roundwood processing is projected to generate over 329 mtons of side-streams per year, including wood chips, particles and residues, with 42 mtons originating from Europe [1] . Due to their molecular complexity, these side streams are highly recalcitrant and are primarily utilised for energy production. However, there is a growing interest in […]
P1.2 – Acidic Treatment of Pulp Increases Swelling Properties and Chemical Reactivity
Cellulose is an excellent raw material for a wide range of products, including cellulose derivatives and regenerated cellulose. Key factors when producing these products are high accessibility to solvents and reagents, and high reactivity. Cellulose with enhanced reactivity could drastically reduce chemical consumption during derivatization, which would be sustainable, and economically beneficial for several industries. […]
P1.3 – From poplar wood wastes to lignocellulosic fibers and MFCs: assessment of a new mild alkaline pulping process and comparison with Kraft pulping
Alkaline pulping processes on different biomasses, used at large scales, have well-known and proven effectiveness. Kraft cooking produces cellulose for paper and dissolving-pulp qualities (case of the PHK process), but its high production unit’s capabilities make it difficult to use them for small biomass quantities, such as biomass wastes. Using such material, our study presents […]
