What is claimed: 1. A method for decomposing a composition comprising a petroleum-based material, comprising: subjecting said composition to microwave radiation for a time sufficient to at least partially decompose said composition, wherein said microwave radiation comprises at least one frequency
What is claimed: 1. A method for decomposing a composition comprising a petroleum-based material, comprising: subjecting said composition to microwave radiation for a time sufficient to at least partially decompose said composition, wherein said microwave radiation comprises at least one frequency component in the range of from about 4 GHz to about 18 GHz; and recovering decomposed petroleum-based material at a pressure less than one atmosphere, wherein said composition is derived from a tire. 2. The method of claim 1, wherein said composition is decomposed to form at least one of oil, gas, steel, sulfur, and carbon black. 3. A method for decomposing a composition comprising a petroleum-based material, comprising: subjecting said composition to microwave radiation for a time sufficient to at least partially decompose said composition, wherein said microwave radiation comprises at least one frequency component in the range of from about 4 GHz to about 18 GHz; and recovering decomposed petroleum-based material at a pressure less than one atmosphere, wherein said composition comprises plastic. 4. The method of claim 3, wherein said plastic comprises ethylene (co)polymer, propylene (co)polymer, styrene (co)polymer, butadiene (co)polymer, polyvinyl chloride, polyvinyl acetate, polycarbonate, polyethylene terephthalate, (meth)acrylic (co)polymer, or a mixture thereof. 5. The method of claim 3, wherein said composition is decomposed to form at least one monomer. 6. A method for decomposing a composition comprising a petroleum-based material, comprising: subjecting said composition to microwave radiation for a time sufficient to at least partially decompose said composition, wherein the temperature of said composition does not exceed about 700° F.; wherein said microwave radiation comprises at least one frequency component in the range of from about 4 GHz to about 18 GHz; and recovering decomposed petroleum-based material at a pressure less than one atmosphere. 7. The method of claim 6, wherein said composition is exposed to less than about 12% oxygen. 8. The method of claim 6, wherein said composition is exposed to less than about 8% oxygen. 9. The method of claim 6, wherein said composition is exposed to an inert gas atmosphere. 10. The method of claim 6, wherein said microwave radiation comprises at least one frequency component in the range of from 4.0 GHz to about 12 GHz. 11. The method of claim 6, wherein said composition is exposed to less than atmospheric pressure. 12. The method of claim 6, wherein said composition is exposed to a pressure of less than about 40 Torr. 13. The method of claim 6, wherein said composition is exposed to a pressure of less than 20 Torr. 14. The method of claim 6, wherein said composition is exposed to a pressure of less than 5 Torr. 15. The method of claim 6, wherein the temperature of said composition does not exceed about 500° F. 16. The method of claim 6, wherein the temperature of said composition does not exceed about 465° F. 17. The method of claim 6, wherein said microwave radiation comprises one or more pre-selected microwave radiation frequencies. 18. The method of claim 17, wherein said one or more pre-selected microwave radiation frequencies is in the range of from about 4.0 and about 7.2 GHz. 19. The method of claim 17, wherein said one or more pre-selected microwave radiation frequencies is in the range of from about 4.0 and about 6.0 GHz. 20. The method of claim 6, wherein said microwave radiation comprises a sweeping range of microwave radiation frequencies. 21. The method of claim 20, wherein the range of microwave radiation frequencies comprises a bandwidth of about 4 GHz. 22. The method of claim 20, wherein the range of frequencies of said radiation is in the C-Band frequency range. 23. The method of claim 20, wherein the range of frequencies of said radiation is in the X-Band frequency range. 24. The method of claim 20, wherein the frequencies of said radiation is in the range of from about 5.8 GHz to about 7.0 GHz. 25. The method of claim 20, wherein the frequencies of said radiation is in the range of from about 7.9 GHz to about 8.7 GHz. 26. The method of claim 20, wherein the sweeping range of microwave radiation frequencies encompasses one or more pre-selected microwave radiation frequencies. 27. The method of claim 26, wherein the range of microwave radiation frequencies is about +/-2 GHz of the pre-selected microwave radiation frequency.
