From biorefineries to bioproducts: conversion of pretreated pulp from biorefining streams to lignocellullose nanofibers, TAPPI Journal April 2019
ABSTRACT: This study investigates the use of pretreatment and enzymatic hydrolysis side streams and conver-sion to lignocellulose nanofibers. We used a steam-exploded and partial enzymatic hydrolyzed hardwood pulp and an organosolv pretreated softwood pulp to prepare lignocellulose nanofibers (LCNF) via microfluidization. The ener-gies applied on fibrillation were estimated to examine the energy consumption levels of LCNF production. The ener-gy consumptions of the fibrillation processes of the hardwood LCNF production and the softwood LCNF production were about 7040-14080 kWh/ton and 4640 kWh/ton on a dry material basis, respectively. The morphology and dimension of developed hardwood and softwood LCNFs and the stability and rheological behavior of their suspen-sions were investigated and are discussed.

Editorial: Foam forming: Technology of many opportunities, TAPPI JOURNAL August 2019
ABSTRACT: Over the past ten years, the forest sector has faced big changes due to the decreased demand of printing papers and the fast growth in packaging and tissue products. Weekly news on the marine waste problem and global warming have raised public awareness and stimulated increased interest in bio-based materials, chemicals, and fuels.

Measurement of the dynamics of fluid sorption for tissue papers, TAPPI Journal July 2019
ABSTRACT: Liquid absorption ability belongs to the most important features of tissue papers. Due to non-homo-geneous internal and superficial structures, precise and fast evaluation of this property is challenging. The main aim of the presented research was to design an experimental device dedicated to the measurement of the kinetics of wetting phenomenon for tissue papers. The second aim was to evaluate whether it was possible to use image analysis for more precise characterization of liquid absorption properties of tissue paper. The obtained results showed that the method used, based on image analysis supported by gravimetric methods, proved to efficiently and quantitatively characterize the dynamics of liquid absorption for tissue papers. Supplementary parameters such as absorption anisotropy and in-plane velocity were obtained. Different experi-mental results were obtained for various tissue paper grades. Furthermore, water absorption capacity calculated from image analysis data correlated with results obtained according to the standard method EN ISO 12625-8:2010 “Tissue paper and tissue products—Part 8: Water-absorption time and water-absorption capacity, basket-immersion test method.” Hence, the presented device quantitatively characterizes and discriminates water absorption phenom-enon for tissue papers.

Evaluating hardness and the S-test, TAPPI Journal March 2019
ABSTRACT: The corrugated industry typically quantifies crush resistance using the Concora corrugated medium test (CMT) on fluted medium or flat crush on combined board. These tests compress the materials until the point of complete failure of the flutes. Combined board elastically resists crushing forces until a certain point, the hardness of the structure, while additional load causes permanent damage and deformation. This study investigates how hardness can be measured directly from a load curve collected during CMT (or flat crush) testing and how it varies throughout the North American paper supply. It also explores how hardness corre-lates with the values obtained from the newly developed S-test. This new test method deserves further study as a potentially more appropriate specification for crush resistance of corrugated medium.

Editorial: Nanocellulose: What's next?
Many of the researchers in this field in the late 1990s and early 2000s were challenged in terms of translation research issues due to the limited production capacity of nanocellulosics on a global stage. To address this call, several pilot-plant production plants have been developed and can now deliver NC on multikilo/ton scale as these issues are gradually being resolved.
