To provide a method for producing a biodegradable molded product, capable of adding a biodegradable binder resin into a biodegradable molding material without using any organic solvent, so that the binder resin is uniformly dispersed into the molding material and retained, when the molded product is produced by integrating the molding material and the binder resin.
This method for producing the biodegradable molded product comprises a process in which an aqueous dispersion of the biodegradable binder resin is added to the biodegradable molding material, another process in which an aqueous dispersion medium is removed from the molding material and the molding material retaining the aqueous dispersion is heated to such an extent that the binder resin is molten, a third process in which the heated molding material is pressed, and the other process in which the pressed molding material is cooled. The aqueous dispersion reduces an environmental load when the molded product is produced, and prevents a tendency of uneven distribution of the biodegradable binder resin caused by conventional methods.
