Guest Editorial: Addressing nanocellulose commercialization needs: R&D collaboration is vital, TAPPI Journal April 2019

This special edition of TAPPI Journal presents demonstrable progress toward the goal of commercial-scale implementation of nanocellulose. Steve Winter of International Paper and I, as co-leads of the Cellulosic Nanomaterials team of the Alliance for Pulp & Paper Technology Innovation (APPTI), see this widespread engagement of the research community in developing innovations as critical to successful commercialization. Congratulations and thanks to TAPPI and to the researchers publishing in this issue and elsewhere.

From biorefineries to bioproducts: conversion of pretreated pulp from biorefining streams to lignocellullose nanofibers, TAPPI Journal April 2019

ABSTRACT: This study investigates the use of pretreatment and enzymatic hydrolysis side streams and conver-sion to lignocellulose nanofibers. We used a steam-exploded and partial enzymatic hydrolyzed hardwood pulp and an organosolv pretreated softwood pulp to prepare lignocellulose nanofibers (LCNF) via microfluidization. The ener-gies applied on fibrillation were estimated to examine the energy consumption levels of LCNF production. The ener-gy consumptions of the fibrillation processes of the hardwood LCNF production and the softwood LCNF production were about 7040-14080 kWh/ton and 4640 kWh/ton on a dry material basis, respectively. The morphology and dimension of developed hardwood and softwood LCNFs and the stability and rheological behavior of their suspen-sions were investigated and are discussed.

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.

A new approach for the preparation of cellulose nanocrystals from bamboo pulp through extremely low acid hydrolysis, TAPPI Journal January 2020

ABSTRACT: As a renewable and biodegradable nanomaterial, cellulose nanocrystal (CNC) has a wide range of potential applications, but production of CNC faces significant challenges in capital investment and manufacturing cost. In this work, the one-step preparation of CNC from bleached kraft bamboo pulp by extremely low acid (concen-tration of acid = 0.1 wt%) hydrolysis was demonstrated. The experimental data indicated that the yield of CNC was strongly affected by the operating pressure and concentration of hydrochloric acid (HCl), as well as temperature. Rod-like CNC with a mean particle size of 524 nm was obtained through an extremely low acid (ELA) hydrolysis pro-cess. The yield of CNC can reach to 37.1% by an ELA hydrolysis process at 180°C for 60 min with 0.08 wt% HCl and 20 MPa operating pressure. The Fourier transform-infrared spectroscopy (FTIR) measurements show that the as-pre-pared CNC maintained cellulose structure. Compared with a conventional CNC prepared by strong sulfuric acid (H2SO4) hydrolysis, the CNC prepared by ELA hydrolysis process exhibited much higher thermal stability.
