1. A thermoplastic acrylonitrile-butadiene-styrene copolymer/lignin blend comprising:
(i) an amount of lignin, wherein the lignin is derived from a lignocellulosic feedstock, and wherein the lignin has been isolated from the lignocellulosic feedstock;
(ii) an amount of a first acrylonitrile-butadiene-styrene copolymer; and
(iii) an amount of compatibilizing agent, the compatibilizing agent including a first amount of a second acrylonitrile-butadiene-styrene copolymer having a butadiene content of at least about 50% by weight, which is a different copolymer than the first acrylonitrile-butadiene-styrene copolymer, and a second amount of a monomeric maleic anhydride, wherein the second acrylonitrile-butadiene-styrene copolymer and the monomeric maleic anhydride are separate compounds within the blend,
wherein the lignin is present in an amount of at least 5 wt % by total weight of components (i) and (ii), components (i) and (ii) are present together in an amount from 75 wt % or greater by weight of the total weight of the blend, and the total amount of the compatibilizing agent comprises from about 0.5 to 25% by weight of the total weight of the blend.
