Abstract: A method of producing a polyurethane based foam that includes providing a ground crop residue having an average particle size of less than 10 mm and that is prepared by grinding crop residues, providing a polyurethane system that includes an isocyanate component and an isocyanate-reactive component, of which the polyurethane system has an isocyanate index from 70 to 350, forming a modified polyurethane system by adding the ground crop residue to the polyurethane system in a range from 1.0 wt % to 20.0 wt %, based on a total weight of the modified polyurethane system, and forming the polyurethane based foam so as to have an applied density from 30 kg/m3 to 75 kg/m3, according to ASTM D-1622, and to have the ground crop residue embedded within polyurethane polymers that are a reaction product of the isocyanate component and the isocyanate-reactive component of the polyurethane system.
