ABSTRACT The increasing use of wood and wood‐based composites in construction reflects a global shift toward renewable materials that support sustainable development objectives, including carbon reduction and responsible resource use. While wood offers substantial environmental benefits compared to conventional materials such as concrete and steel, its

The limits of delignification in kraft cooking [Elektronisk resurs] [PDF]
The perspective of the article is to explore kraft cooking at the limits of delignification, i.e. what degree of delignification is needed to obtain fibre liberation and what is the maximum degree of delignification possible in the kraft pulping stage ...

Microwave‐conditioned olive pomace was fractionated with deep eutectic solvents (DESs) spanning acidic, neutral, alkaline, and chemo‐enzymatic regimes. The alkaline DES provided the best balance between delignification and carbohydrate preservation, yielding a fermentable glucose/xylose stream suitable for Haloferax mediterranei fermentation and poly(3‐

Autonomous and Continuous Atmospheric Water Harvesting Using Modified Wood
A rigid, hydroxyl‐rich wood skeleton with graded channels is used as a multifunctional host to co‐incorporate a PNipam/PAA network and LiCl, creating a high‐performance sorbent for atmospheric water harvesting. The composite achieves rapid sorption, efficient low‐temperature desorption, and stable cycling, enabling a solar‐powered device with a high ...

Fractionation of Pinus radiata wood by combination of steam explosion and organosolv delignification
This work proposes a sequential combination of steam explosion and organosolv delignification for Pinus radiata fractionation. An efficient pretreatment to fully optimize the use of lignocellulosic materials is the key to make a biorefinery profitable ...
