Production of antimicrobial paper using nanosilver, nanocellulose, and chitosan from a coronavirus perspective, TAPPI Journal July 2021
ABSTRACT: The pulp and paper industry has an opportunity to play a vital role in breaking the spread of the COVID-19 pandemic through production that supports widespread use of antimicrobial paper. This paper provides a brief review of paper and paper-related industries, such as those producing relevant additives, and R&D organizations that are actively engaged in developing antimicrobial papers. The focus here is on the potential of three nano-additives for use in production of antimicrobial papers that combat coronavirus: nanosilver, nanocellulose, and chitosan. Various recent developments in relevant areas and concepts underlining the fight against coronavirus are also covered, as are related terms and concepts.

Guest Editorial: Research and development in the post COVID-19 era, TAPPI Journal June 2021
Science and technology occupy prominent roles in solving global problems. The ongoing COVID-19 pandemic has reinforced the importance of science regarding decision-making, saving lives, and safeguarding the environment. While information technology (IT) and IT-based tools have garnered much needed attention in the past few decades, other areas such as manufacturing engineering, biotechnology, and pharmaceuticals are finding their right places in gaining public and political support and attention--thanks to COVID-19! Such public attention has highlighted vulnerabilities due to lack of investments in manufacturing and materials engineering, as well as the need for strategic investments in these areas.

Determining operating variables that impact internal fiber bonding using Wedge statistical analysis methods, TAPPI Journal November 2021
ABSTRACT: In this study, Wedge statistical analysis tools were used to collect, collate, clean up, plot, and analyze several years of operational data from a commercial paper machine. The z-direction tensile (ZDT) and Scott Bond tests were chosen as representative of fiber bond strength. After analyzing thousands of operational parameters, the ones with the most significant impact upon ZDT involved starch application method, starch penetration, and the amount of starch applied. Scott bond was found to be significantly impacted by formation and refining. Final calendering of the paper web has also shown an impact on internal fiber bonding.

Editorial: Innovation: How useful is it?, TAPPI Journal February 2022
ABSTRACT: Innovation has become a genuine buzz word to promote one’s product or company, to highlight its strength, and to enhance its visibility. The use of words like novel, innovative, etc., help with market-ability, enhance economic strength, and elevate initial public offering (IPO) status. Genuine innovation helps with improving lifestyles, health, the environment, and the economy.

Considerations in managing wastewater odor at pulp and paper operations, TAPPI Journal March 2022
ABSTRACT: Many pulp and paper mills are, at least periodically, faced with the release of odors that can migrate offsite and be considered a nuisance by nearby residents. At chemical pulp mills, perceptible odors associated with reduced sulfur compounds (RSCs) are common, many of which are highly perceptible owing to their low odor thresholds. As releases of RSCs and other odorous substances from production processes are progressively controlled, the proportional contribution from wastewater treatment systems to areal odors can increase. This review paper summarizes important fundamentals of odor generation, source identification, and control. Common odorous substances are identified, and mechanisms for their generation are summarized. Approaches for measuring odorous substances are detailed to enable more effective management, and various odor control strategies are discussed.

Editorial: Unlock the gates! TAPPI Journal moves to fully Open Access research for all, TAPPI Journal March 2022
TAPPI and the TAPPI Journal (TJ) Editorial board and staff are pleased to announce that TJ’s content is now immediately open access (OA), with no embargoes. In 2020, the journal had adopted a hybrid OA model wherein its peer-reviewed research was free to TAPPI members for one year and then became free to all on the one-year anniversary of a research paper’s publishing date. Now, research is immediately accessible to all, increasing visibility and engagement for authors and providing an unobstructed view for researchers, students, and other interested parties.

Effects of metal surface morphology on deposition behavior of microstickies from papermaking white water, TAPPI Journal July 2023
ABSTRACT: Deposition of small adhesive particles, called microstickies, onto pulp processing equipment and paper machines causes quality and operational problems for recycling mills. The factors that control deposition of microstickies onto surfaces of metal parts remain unclear. In this work, aluminum surfaces with a range of surface roughness were exposed to slurries containing microstickies. The deposition results showed that flat surfaces promote the aggregation and deposition of microstickies particles. Uneven surfaces tended to favor deposition of smaller microstickies, 0.2•1 µm, which may be related to greater contact area presented by the rougher surface. This work provides insights into the deposition of microstickies.

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.
