Abstract: The present invention is a method to make an environmentally friendly polyurethane molded article (100) comprising at least 20 percent renewable materials and molded articles made therefrom. Specifically, the method provides for molding a polyurethane coated sandwich structure (40) comprising a honey comb core (30) having fiber reinforcing layers (10, 20) to provide an environmentally friendly polyurethane molded article with a desired shape such as an automobile load floor. The polyurethane coating is derived from a polyurethane—forming mixture comprising an isocyanate component and a polyol component. Specifically, the polyol component comprises one or more natural oil based polyol, preferably comprising at least one of a hydroxymethylated fatty acid or a hydroxymethylated fatty acid (methyl) ester.
