1. A wood plastic composite comprising a blend of:
a) a thermoplastic resin; b) a cellulosic filler selected from the group consisting of wood fiber, rice hull, bamboo, soy hull, switchgrass, rice straw, sugar beet pulp, sugar cane bagasse, dry rosemary, corn stover, delipidated cake from soybean, canola, cottonseed, sunflower, jatropha seeds, paper pulp and waste paper; c) oleaginous microbial cells extracted of triglycerides yielding de-fatted biomass; d) optionally wood product composite lubricant; wherein the wood plastic composite comprises a reduced or eliminated amount of the wood product composite lubricant and maintains an equivalent appearance profile as compared to a wood plastic composite containing the wood product composite lubricant but lacking the biomass.
