Abstract: Persimmon tree pruning waste (PTPW) was subjected to different fractionation methods and bioconversion conditions to obtain lignin nanoparticles and cellulosic ethanol. Lignins were converted into manometric structures (Ø = 150–250 nm) with a high degree of uniformity, spherical or nearly spherical conformation, homogeneous dispersion and colloidal stability, with yields ranging from 16 % to 30 % by weight. Separate hydrolysis and fermentation of the pre-treated biomass indicated that the condition of slow acid addition followed by alkaline treatment provided a biomass more susceptible to enzymatic hydrolysis, with fermentable sugar yields above 60 % and an ethanol yield of 0.37 (g g−1). Thus, the use of PTPW to obtain lignin nanoparticles and cellulosic ethanol is feasible and results in value-added products; this study is the first in the literature to promote the use of PTPW.
