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.

Recycling performance of softwood and hardwood unbleached kraft pulps for packaging papers, TAPPI Journal February 2023
ABSTRACT: The scope of this work is to evaluate the recyclability potential of hardwood and softwood unbleached kraft pulps, leading to a sound basis for comparison and even to support a decision about fibers accord-ing to the performance achieved. The influence of successive recycling cycles (up to 10 cycles) on the fiber morphol-ogy, pulp suspension drainability, water retention capacity, and handsheet mechanical properties were studied for Eucalyptus globulus and Pinus sylvestris unbleached kraft pulps. The performance of these pulps as linerboard and corrugating medium for packaging was also evaluated. The requirements for brown kraftliner and for high perfor-mance recycled fluting grades is preserved for E. globulus pulp during all 10 recycling cycles, evidenced by the mod-erate decrease of burst index and crush resistance index and by the short-span compression index, whereas the P. sylvestris pulp loses this rating after the second cycle. These results strongly support the higher performance of E. globulus pulp for recycling as compared with softwood kraft pulp from the perspective of packaging papers.

A fast and non-destructive alternative to the burnout method for paperboard quality inspections using phase-contrast X-ray imaging, TAPPI Journal February 2023
ABSTRACT: An X-ray based quality inspection method for paperboard was implemented and tested as a fast and non-destructive alternative to the burnout method. An argument against X-ray imaging for inspection of paper and paperboard has been that X-ray absorption is low in paper. To overcome this limitation, we used phase-contrast X-ray imaging (PCXI), which gives higher contrast than conventional attenuation-based imaging for low-absorbing materials such as paper. The suggested PCXI method was applied to previously prepared and quality rated samples using the burnout method. A strong similarity between the burnout images and the PCXI images was observed. In conclusion, further development of the phase-contrast X-ray method would provide an interesting option for replacing or complementing the standard burnout method.
