Disclosed is a portable cooler device comprised of recyclable materials. Some embodiments of the device comprise components constructed entirely of, or substantially of, cellulose. Other embodiments may be comprised of recyclable materials not classified as cellulose such as, but not limited to, cotton, bamboo, hemp, or other natural fibers. The specific percentages of recycled and/or recyclable content are not limiting factors for the invention; however, most embodiments have consistent materials of construction such that the entire device may be recycled in a single recycling process without the need for deconstruction. Further, if not recycled, embodiments are operable to biodegrade within a reasonable amount of time when exposed to the elements in a landfill. Typical embodiments are comprised of an inner shell, an outer shell having an integrally hinged lid, and pressed cellulose insulating boards sandwiched between the shells.
