Hydrolysis with aqueous H2SO4 affords nanocellulose in nanocrystal form. Comprised of cellulose I only, CNC has a low length/diameter “aspect” ratio (10-100), and a tensile strength similar to that of aramid-fiber (10 GPa). Its industrial production has an estimated production cost ranging from $3632/t to $4420/t.22 Feedstock cost and capital investment being the major cost drivers.22 Remarkably, in the same year of these estimates (2017) for large scale production, CNC was reported to be actually sold at $1,000/kg.23
