Abstract
The present invention provides, among other things, methods including the steps of providing a cellulosic biomass, associating the cellulosic biomass with an organic liquid to form a mixture, treating the mixture to reduce the moisture content of the mixture to 30% or below (if necessary), and processing the mixture to produce cellulose nanofibrils in a slurry. In some embodiments, provided methods allow for the production of high solids content slurries containing 4% or more cellulosic nanofibrils.
