Abstract: A biomass-based thermoplastic polyurethane is provided. The biomass-based thermoplastic polyurethane is a reaction product of a composition. The composition includes 1-50 parts by weight of a modified lignin, 50-99 parts by weight of a first polyol, and 40-60 parts by weight of a diisocyanate. The modified lignin has an OH value of less than 3.0 mmol/g. The sum of the modified lignin and the first polyol is 100 parts by weight.
