Editorial: ”Didn’t know we knew that” • Rediscovering the fundamentals, TAPPI Journal April 2022

ABSTRACT: Access to today’s extensive electronic information archives is certainly an amazing feat of technology. Nonetheless, it can sometimes be difficult to find pulp and paper industry process-specific resources that are easily digestible and tailored to help us in our day-to-day work.

Real-time monitoring of bubble size distribution in a foam forming process, TAPPI JOURNAL August 2019

ABSTRACT: Foam forming is an intricate option to lessen fiber flocculation and to get better energy and water efficiency when making fiber-based products. Developed during the 1970s, this approach has recently received renewed attention, mainly because it also offers possibilities to widen the fiber-based product portfolios with novel and more valuable products. In addition to air content, bubble size is the most important property of foam. Foam quality control is essential for building real-world foam forming processes. In this work, we show how bubble size can be monitored with direct optical imaging in real time in real process conditions, and how such analysis helps adjust foam quality and discover process faults in foam forming.

Fundamental molecular characterization and comparison of the O, D0, and E stage effluents from hardwood pulp bleaching, TAPPI Journal 2019

ABSTRACT: The present study characterized effluents from the O, D0, and E stages using nuclear magnetic reso-nance (NMR) and gel permeation chromatography (GPC) techniques to better understand the chemical nature of the dissolved organics formed from the bleaching of a high-yield hardwood kraft pulp. Understanding the structures and molecular weight distribution of these organics is the first step in developing methods to mitigate these contam-inates in the discharged effluents. The results indicated that the molecular weight distribution (MWD) of the dis-solved organics from oxygen delignification effluent is broader than those from D0 and E stage effluents. In addition, the O stage filtrate contained considerable amounts of lignin and xylan fragments, which showed its efficiency in removing such materials. The effluent from the D0 stage contained a lower amount of high molecular weight frag-ments and a higher amount of low molecular weight fragments versus the O-stage filtrate. Aromatic structures were nearly absent in the D0 stage filtrate, but the degraded organic material, presumably from oxidized lignin, contained olefinic (C=C) and carbonyl (C=O) functional groups. Furthermore, higher molecular weight fragments were detected in the E-stage effluent, presumably due to the extensive solubilization and removal of the oxidized lignin generated from the D0 pulp.

Guest Editorial: Addressing nanocellulose commercialization needs: R&D collaboration is vital, TAPPI Journal April 2019

This special edition of TAPPI Journal presents demonstrable progress toward the goal of commercial-scale implementation of nanocellulose. Steve Winter of International Paper and I, as co-leads of the Cellulosic Nanomaterials team of the Alliance for Pulp & Paper Technology Innovation (APPTI), see this widespread engagement of the research community in developing innovations as critical to successful commercialization. Congratulations and thanks to TAPPI and to the researchers publishing in this issue and elsewhere.
