Editorial: The state of cellulosic nanotechnology: June conference captures current and emerging trends, TAPPI Journal July 2023
ABSTRACT: From June 12-16, 253 participants from 18 countries gathered in Vancouver, BC, Canada, for TAPPI’s 2023 International Conference on Nanotechnology for Renewable Materials. Representatives from academia, industry, and federal research institutes could choose from among 140 technical presentations on production, characterization, applications, and functionalization of renewable nanomaterials.

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.

Multifunctional starch-based barrier materials, TAPPI Journal August 2021
ABSTRACT: Natural and renewable polymer-based barrier materials play an inevitable role in a sustainable economy. Most commercially available barrier materials are either based on multiple layers of synthetic polymers or petroleum-based chemicals. Tremendous amounts of research are being done in academia and industry to replace these synthetic barrier materials with natural and environmentally friendly materials. The current work summarizes the application of starch-based materials for various barrier applications, such as water vapor, oxygen, liquid water, oil, and grease. Also, exotic starch-based barrier materials for the application of sound, ultraviolet, and thermal barrier applications are reviewed. The potential of starch-based materials to offer antimicrobial and antiviral properties is discussed. Finally, commercially available starch-based barrier materials have been summarized.

Continuous digester rapid thinning, TAPPI Journal June 2024
ABSTRACT: Carbon steel continuous digesters built after the early 1980s are fully stress relieved, so stress corrosion cracking has been less of a concern. However, these newer digesters were designed to run modified cooking processes that have turned out to be much more corrosive than those running with conventional cooking. This corrosion is mainly associated with softwood digesters and appears to be flow related. Average corrosion rates of 40 mil/year are possible on the exposed shell between the wash and extraction screens. The corrosion patterns are visually distinct from surfaces in the upper digester and below the wash screens. This paper goes into practical detail on where it occurs, the causes, visual identification, inspection planning and results evaluation, and finally, how to mitigate this damage, which consists of applying a corrosion resistant barrier. Some discussion on dealing with general corrosion throughout the digester is included.

Editorial: Special coating issue contains highlighted works from TAPPICon 2023, TAPPI Journal November 2023
ABSTRACT: Did you know that TAPPI’s Coating and Graphic Arts Division has changed its name to Coating, Printing, and Surface Enhancement (CPSE) Division? This change occurred mid-year, as our members realized that the new name fits much better with the day-to-day workings of the Division, as well as the broader activities to functionalize and add value to paper and paperboard that continue to expand into new arenas.

Editorial: The innovation engine and the forest products industry value chain, TAPPI Journal October 2023
ABSTRACT: The forest products industry (FPI • pulp, paper, paperboard, building products, allied products, and byproducts) has been continuously innovating as it manufactures and delivers value-added products to consumers worldwide. Integrated pulp and paper mills produce pulp, paper, paperboard, and byproducts like turpentine, tall oil, methanol, lignin, and other chemicals.

Editorial: Transform presentations to TAPPI Journal research papers by following basic steps, TAPPI Journal August 2024
ABSTRACT: Very often, important research findings are communicated in presentation form at industry conferences like those TAPPI holds. While this is a great way to highlight your work, it has some limitations when compared to a peer-reviewed TAPPI Journal paper. Presentations are limited to a specific event, while publishing papers in a peer-reviewed journal means that your work becomes part of scientific literature that is available to a broader audience. Also, a research paper allows for a more detailed explanation of the methods, data, and conclusions than the time-constrained format of a presentation.

Editorial: Special issue showcases new additive approaches for a lignocellulose-based future, TAPPI Journal January 2024
ABSTRACT: Lignocellulose-derived materials are inherently renewable and are of benefit not only through their recyclability and biodegradability, but also from carbon sequestration during the production of the base raw material. With regulatory agencies tightening restrictions and consumer habits slowly shifting, the paper industry is well positioned to fill a market need for renewable bio-based materials. Although the inherent benefits of lignocellulose-based products are many, all too often, the end-product does not meet the required performance or cost in use desired by end-users. This creates obstacles for a more renewable economy that relies less on petroleum-derived products.

Editorial: Surface energy in printing is the focus of runner-up, TAPPI Journal May 2024
ABSTRACT: The runner-up to the 2023 TAPPI Journal Best Re-search Paper was “Surface energy considerations for offset printing of coated paper and pa-perboard,” co-authored by Janet Pres-ton, Andrew Findlay, Jonathan Keen, and Eli Gaskin of Imerys Minerals in Par, England, UK. Their research appeared in the November 2023 special coating issue organized by TAPPI Journal Editorial Board Members Steve Ottone, Gregg Reed, and Greg Welsch.
