1. A method of making a composition comprising a thermoplastic polymer and a biomass, wherein the biomass comprises an antioxidant stabilizer comprising lignin, wherein the lignin has an average particle size of from about 2 micrometers to about 8 micrometers, and wherein the composition comprises cellulose and/or hemicellulose in an amount no greater than 20% based on the weight of the biomass, the method comprising the steps of:
(a) obtaining a lignin by exposing a biomass to a fluid having a temperature of from about 340° C. to about 400° C. and a pressure of from about 225 bar to about 250 bar; and
(b) combining the lignin with the thermoplastic polymer.
