Abstract

A method of dissolving lignocellulosic biomass waste includes obtaining raw lignocellulosic biomass waste, reducing a size of the biomass waste to provide a biomass particle size of less than about 200 μm; using dimethyl sulfoxide (DMSO), sodium hydroxide (NaOH) and trifluoroacetic acid (TFA) solvents to dissolve the biomass particles and achieve a dissolved lignocellulose solution. The present method dissolves at least about 94% of the lignocellulose fraction in the waste biomass. In an embodiment, the biomass particle size can be about 180 μm.
