A process for producing a flexible foam includes introducing a polymer into an autoclave chamber or mold cavity, pressurizing the autoclave chamber or mold cavity to an elevated pressure using a supercritical fluid, maintaining the elevated pressure within the autoclave chamber or mold cavity for a sufficient time to infuse the supercritical fluid into the polymer, reducing the pressure within the autoclave chamber or mold cavity to cause the infused supercritical fluid to form cell nuclei throughout the polymer, and allowing the cell nuclei to expand to form a foam from the polymer within the autoclave chamber or mold cavity. The polymer is composed of one or more non-cross-linked thermoplastic polymers that are recyclable and/or biodegradable. The polymer may be introduced into the autoclave chamber of mold cavity as a solid sheet or block, or the polymer may be dissolved in a solvent.
