Resistance of thermo-hygro-mechanically (THM) densified wood to degradation by white rot fungi [PDF]

, 2017
Colonisation and degradation by the white rot fungi, Trametes versicolor and T. pubescens, were studied in wood of Norway spruce and beech subjected to three different treatments: (1) hygro-thermal treatment (160°C and 180°C), (2) mechanical ...

On the nature of the selectivity of oxygen delignification

Nordic Pulp & Paper Research Journal
Abstract This work has focused on oxygen’s role in the delignification process within the context of pulp production. We have investigated the role of oxygen in a complex set of chemical reactions taking place during this process, including both oxidative and non-oxidative reactions.

Valorisation of lignin – Achievements of the LignoValue project [PDF]

Lignocellulosic biorefinery for production of biofuels, materials and chemicals requires valorization of all fractions including lignin. As a consequence of its poly-aromatic structure, lignin potentially serves as a source for aromatic chemicals.

ON THE RECOVERY OF HEMICELLULOSE BEFORE KRAFT PULPING

BioResources, 2012
To assess the feasibility of implementing hemicellulose recovery stages in kraft mills, Eucalyptus globulus wood samples were subjected to aqueous treatments with hot, compressed water (autohydrolysis processing) to achieve partial dissolution of xylan ...

Development of Molded Fibers-Based Packaging from Sugarcane Bagasse for Sustainable Alternatives to Single-Use Plastics

BioResources
Molded fiber-based packaging has recently surged in popularity as a replacement for single-use plastics (SUPs). However, key challenges include the lack of low-cost, high-yield sustainable fibers that provide adequate strength and moldability while ...

ANALYSIS OF STRUCTURAL CHANGES OF MASSON PINE LIGNIN REACTED WITH SUPEROXIDE ANION RADICAL BY NMR SPECTROSCOPIES

BioResources, 2010
Oxygen delignification can be considered to be the most important part of TCF and ECF bleaching sequences because it allows for cleaner production of pulp.

EVALUATION OF PRE-HYDROLYZED SODA-AQ DISSOLVING PULP FROM POPULUS DELTOIDES USING AN ODED BLEACHING SEQUENCE

BioResources, 2012
In the present work, the production of dissolving pulp from fast growing 30-year-old local plantation aspen was investigated. The mill-made chips of aspen (Populus deltoides) after being pre-hydrolyzed with water at 170 ºC, were pulped with a soda-AQ ...
