1. A removable adsorbent cartridge for removal of gaseous contaminants comprising: a plurality of parallel, non-wound adsorbent sheets, mechanically spaced so as to allow gas flow between each sheet in the plurality, wherein each adsorbent sheet is formed from a mixture comprising a polymer and an adsorbent, wherein the sheets are spaced by ribs protruding from each sheet and molded directly out of the adsorbent sheet; andone or more fasteners disposed within the adsorbent cartridge, wherein the one or more fasteners secures the plurality of said sheets together; wherein the cartridge does not further comprise a rigid shell encasing the cartridge; and wherein the cartridge is self-supporting without the need for external support or gluing or fusing the sheets together. 2. The adsorbent cartridge of claim 1, wherein the non-wound adsorbent sheets are planar. 3. The adsorbent cartridge of claim 1, wherein the one or more fasteners comprise one or more fasteners independently selected from stakes, staples, wires, rods, cords, plastic bands, elastic bands, and rivets. 4. The adsorbent cartridge of claim 1, wherein the one or more fasteners comprise one or more rigid stakes disposed within the cartridge, entering the cartridge from the top or bottom surface sheet. 5. The adsorbent cartridge of claim 4, wherein the rigid stakes are arranged perpendicular to the gas flow. 6. The adsorbent cartridge of claim 4, wherein the rigid stakes are arranged at an angle to the gas flow. 7. The adsorbent cartridge of claim 4, wherein the one or more fasteners comprise a plurality of rigid stakes arranged within the adsorbent cartridge to fasten the adsorbent sheets such that no additional external mechanical support is required during use when the adsorbent cartridge is subjected to a gas flow. 8. The absorbent cartridge of claim 1, wherein the fasteners secure the absorbent sheets together for transport, but additional mechanical support is required during use when the absorbent cartridge is subjected to gas flow. 9. The adsorbent cartridge of claim 1, further comprising a polymer foam that seals the outer surface of the cartridge along the sides that are not in the inlet or outlet flow stream. 10. The adsorbent cartridge of claim 1, further comprising a polymer sleeve surrounding the outer surface of the cartridge along the sides that are not in the inlet or outlet flow stream. 11. The adsorbent cartridge of claim 1, wherein the cartridge comprises square adsorbent sheets arranged into a cube. 12. The adsorbent cartridge of claim 1, wherein the cartridge comprises rectangular adsorbent sheets arranged into a rectangular stack. 13. The adsorbent cartridge of claim 1, wherein the cartridge comprises round or oval adsorbent sheets arranged into a cylinder. 14. The adsorbent cartridge of claim 1, wherein the cartridge comprises triangular or trapezoidal sheets. 15. The adsorbent cartridge of claim 1, wherein said gaseous contaminant is carbon dioxide. 16. The adsorbent cartridge of claim 1, wherein said gaseous contaminant is carbon monoxide, chemical or biological toxins, volatile organic carbons, moisture, acid gases or other impurities in the feed gas stream. 17. The adsorbent cartridge of claim 1, wherein the adsorbent is selected from the group consisting of calcium hydroxide and lithium hydroxide. 18. The adsorbent cartridge of claim 1, wherein the adsorbent material is molecular sieves, activated carbon, or an oxidation catalyst. 19. The cartridge of claim 1, wherein the sheets are extruded sheets. 20. The cartridge of claim 1, wherein the one or more fasteners are two staples. 21. A gaseous contaminant removal system comprising: (1) a removable adsorbent cartridge comprising:a plurality of parallel, non-wound adsorbent sheets, mechanically spaced so as to allow gas flow between each sheet in the plurality, wherein each adsorbent sheet is formed from a mixture comprising a polymer and an adsorbent, wherein the sheets are spaced by ribs protruding from each sheet and molded directly out of the adsorbent sheet; and one or more fasteners, wherein the one or more fasteners secures the plurality of said sheets together; wherein the cartridge does not further comprise a rigid shell encasing the cartridge; and(2) a canister comprising:an inlet through which gas can flow to contact the adsorbent cartridge;an outlet for gas flow; anda plurality of support structures disposed on the interior walls of the canister, which provide mechanical stability to the adsorbent cartridge by restricting movement of the cartridge within the canister during use;wherein the cartridge is placed in the canister such that the gas flow from the inlet of the canister can flow between the adsorbent surfaces in said cartridge.
