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.

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: Progress continues in recovery cycle optimization, TAPPI Journal March 2023
ABSTRACT: Travel came to a halt just before the 2020 International Chemical Recovery Conference (ICRC) was to take place in Brazil. The ICRC was to be co-hosted in 2021 with TAPPI PEERS, but PEERS was eventually cancelled for that year as travel for many had not resumed. In early 2022, The University of Toronto hosted an online meeting in order to bring together the community of researchers and industrial engineers for an ICRC event. At this event, 19 research papers were presented.

The winding mechanics of laminate webs, TAPPI Journal February 2020
ABSTRACT: Models that describe the residual stresses due to winding single-layer webs at the end of roll-to-roll manufacturing machines are mature. These models have been used to reduce or avoid defects that are due to winding. Many laminated products exist where two or more webs have been joined to form a thicker composite web. The properties of the web layers provide a unique functionality to the product being manufactured. No laminate winding models exist in the literature. This paper will focus on the development of a laminate winding model and laboratory test verification of the model.
