A true green cover for industrial waste landfills, TAPPI Journal April 2024
ABSTRACT: Greenhouse gas (GHG) emissions in the United States totaled 5,981 million metric tons of carbon dioxide equivalent (MMT CO2eq) in 2020. Of that, GHG emissions by the pulp and paper sector amounted to 35 MMT CO2eq direct emissions and those by industrial waste landfills summed to 7.4 MMT CO2eq direct emissions. Loss of GHG sinks due to change in land use further contributes to the net GHG emissions. Industrial waste landfills are typically required to comply with certain federal and state regulations, including meeting requirements for final cover systems. Conventional final cover systems have included use of soil covers and/or soil-geosynthetic composite covers. An engineered turf cover provides for an excellent “green” alternative final cover system for industrial waste landfills.This paper discusses various sustainability aspects pertaining to use of an engineered turf final cover, including: (i)significantly low carbon footprint associated with the construction of an engineered turf alternative final coverwhen compared to closure using a traditional or prescriptive cover system; (ii) saving valuable soil and land resourc-es; (iii) saving water resources by reduction in its use during and after construction; (iv) reducing impacts associated with borrow areas; and (v) reducing overall carbon footprint. Further, when using an engineered turf cover, opportunities exist for beneficial reuse of land, including development of solar energy. A brief discussion on the potential fordevelopment of solar energy is included.

The Influence of the Fine Structure of Cellulose on the Action of Cellulases, TAPPI Journal June 2022
ABSTRACT: In the hydrolysis of cellulose with enzymes of Aspergillus niger at 47°C., it shown that a great decrease in the rate occurred in the late stage of the reaction, usually with considerable cellulose still reamaining undissolved.

Editorial: Risks and rewards of research during a pandemic, TAPPI Journal August 2020
ABSTRACT: For universities and research institutions, the arrival of Covid-19 last spring halted activities around the world while exposing the need for detailed Public Health Emergency (PHE) plans to cope with a highly-contagious virus in laboratory and classroom settings. As classroom work switched to online platforms like Zoom, the reality set in that long-term plans were needed to safely keep students learning, research flowing, and universities financially stable.

Modeling of the energy of a smelt-water explosion in the recovery boiler dissolving tank, TAPPI Journal August 2020
ABSTRACT: The explosion energy generated as molten smelt droplets interact with water was evaluated as a function of smelt distribution, water temperature, and smelt temperature using a thermodynamic model. The results show that increasing smelt-to-water volume ratio and water temperature significantly increases the explosion energy, converting a larger proportion of the thermal energy of smelt into mechanical work. To reduce the chance of violent smelt-water explosions, it is important to: i) optimize the shatter jet design and operation to uniformly distribute the smelt over a large area in the dissolving tank; ii) avoid high green liquor temperature and ensure adequate liquor mixing; and iii) avoid upsets that may cause heavy smelt runoff or jellyroll smelt.

Nanocellulose in Japan: An industrial perspective, TAPPI Journal April 2019
ABSTRACT: With the maturing of Japan’s economy, domestic demand for paper and paperboard is more likely to level off in the long term. Japanese paper companies are accelerating overseas production, especially in the emerging Asian markets, while strengthening competitiveness of domestic mills and developing new products. In Japan, we have always focused on emerging technologies and driving innovation in the pulp and paper industry. As a business definition, innovation does not equal innovative technology. Innovative technology can become innovation only when it is commercialized and used in industry.
