Conteúdo: 	In this study, four fillers from forest-based wastes were studied using thermogravimetry and contact angle measurements, and their compatibility with polyurethane were investigated by infrared spectroscopy performed in induced reaction mixtures, wherein the fillers were tested in the presence of excess isocyanate and catalyst. The fillers were then incorporated into rigid bio-based polyurethane foams (RPUFs), which were characterized using thermal and combustion analyses. Wood presented higher compatibility with the polyurethane system, leading to a copolymer formation comprised by urethane groups during its polymerization. Filled RPUF reached increased thermal and dimensional stabilities, and similar thermal conductivities and flammabilities compared with the neat RPUF.
