Fiber-based characterization of pulp refining, TAPPI Journal September 2022
ABSTRACT: Fiber development in pulp refining can be characterized by three parameters: number of impacts on pulp, N; energy per impact, I, and bar force on fibers, F. These parameters enable comparisons of radically different refining conditions; determination of intensity for hardwoods and softwoods; assessment of effect of bar width on fiber shortening; and predictions of tensile strength increases.

Editorial: The road to sustainable packaging: New research on aqueous barrier coating, TAPPI Journal November 2022
Authors: Joel C. Panek and Peter W. Hart | ABSTRACT: This TAPPI Journal Special Coating Issue looks at hot topic research being done in coatings for paper and paperboard. We can feel the “earth shifting” in paper and paper-board packaging due to the strong call by consumers and brand owners for more sustainable and environmentally friendly options. This is the first TAPPI Journal Special Coating Issue to highlight efforts within the paper coating community to produce more sustainable packaging.

Wheat straw as an alternative pulp fiber, TAPPI Journal January 2020
Author: Peter W. Hart | ABSTRACT: The desire to market sustainable packaging materials has led to an interest in the use of various fiber types as a raw material. It has been suggested that the use of annual crops for partial replacement of wood fiber would result in more sustainable products. Several life cycle analyses (LCA) have been performed to evaluate these claims. These LCAs provided conflicting and contradictory results because of the local conditions and the specific pulping processes investigated. Selected LCAs are reviewed and the underlying reasons for these conflicting results are analyzed.

Guest Editorial: Fifty years with TAPPI: A personal and professional perspective, TAPPI Journal June 2020
ABSTRACT: While reflecting on this being my 50th year in TAPPI, it dwaned on me that my father Murray must also have been a TAPPI member for a similar length of time and that he probably joined TAPPI for the same reasons--we both had just started our first jobs in the pulp and paper industry and wanted to learn ecerything we could about the underlying technology.

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.

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.
