“…A credit was applied for sugar sales for both modeled processes, as well as for lignin and lignosulfonate sales for the SEW‐M scenario. Lignosulfonate has a small existing market as it is a by‐product of sulfite pulping 55 . The native lignin stream is considered only for its heat value, though higher value uses are possible in the future.…”

A new forest biorefining model is emerging in which high‐value materials would be produced alongside a cellulosic sugar by‐product in facilities scaled to match fiber availability in northern forests. As these emerging biorefining technologies are being developed by private entities, the economics associated with them are little known. The goal of this study is to use publicly available information to carry out an initial techno‐economic assessment for two emerging biorefining technologies: one that produces sugar and hydrolysis lignin (H‐lignin) from thermomechanical pulping (TMP) and another that produces sugar, lignosulfonate, and nanocellulose. The break‐even price for H‐lignin and nanocellulose is estimated for the respective technology and a credit is applied for cellulosic sugar and other co‐product sales based on current market value. It was found that the minimum product selling price (MPSP) for H‐lignin was within the range of high purity lignin but not enough is known about the properties of H‐lignin to determine if this is a reasonable value for prospective end uses. The estimated MPSP of nanocellulose was found to be considerably lower than for more conventional nanocellulose‐producing methods that use Kraft or dissolving pulp as a starting point. The nanocellulose produced through the second process modeled has different properties than conventional nanocellulose, which need to be further explored. Having a sense of the cost to produce these novel materials will help to direct research on viable end uses. The methodology presented, using only publicly available information, can also be replicated for other emerging technologies. © 2021 Society of Chemical Industry and John Wiley & Sons, Ltd
