The present invention provides integrated bunker storage systems for waste streams based on the composition and characteristics of waste stream. In particular, the present invention provides a process for generating individual waste streams based on a set of material characteristics. According to the system and method of the present invention, individual waste streams from wastes stored in bunkers are mixed in a given feed ratio to generate a food stock that will produce a desired output from a chemical conversion process, e.g., gasification. Optionally, composition data regarding the fed stock can be certified to a third party.

1. A method of producing an engineered feed stock of a desired chemical composition, the method comprising: providing a first bunker of waste constituents of a first type comprising predominately plastic materials separated from a mixed solid waste stream;providing a second bunker of waste constituents of a second type comprising predominately fiber materials separated from the mixed solid waste stream;determining an elemental chemical composition of the waste constituents of the first bunker including at least one of a carbon content (wt %), a hydrogen content (wt %), and oxygen content (wt %);determining an elemental chemical composition of the waste constituents of the second bunker including at least one of a carbon content (wt %), a hydrogen content (wt %), and oxygen content (wt %);determining a quantitative ratio based on at least one of a carbon content (wt %), a hydrogen content (wt %), and oxygen content (wt %), between the waste constituents of the first bunker and the waste constituents of the second bunker that, when the waste constituents of the first bunker and the waste constituents of the second bunker are combined in the quantitative ratio, provides the engineered feed stock of the desired elemental chemical composition; andmixing the waste constituents of the first bunker and the second bunker according to the quantitative ratio based on at least one of a carbon content (wt %), a hydrogen content (wt %), and oxygen content (wt %)to provide the engineered feed stock of the desired elemental chemical composition. 2. The method of claim 1, wherein the mixed solid waste stream comprises municipal solid waste. 3. The method of claim 1, wherein the mixed solid waste stream comprises a source segregated stream. 4. The method of claim 3, wherein the source segregated stream comprises recyclable materials. 5. The method of claim 3, wherein the source segregated stream comprises recycling residue. 6. The method of claim 1, further comprising forming the mixed waste constituents into a densified feed stock. 7. The method of claim 1, wherein at least one of determining a chemical composition of the waste constituents of the first bunker and determining a chemical composition of the waste constituents of the second bunker is based on a collection of chemical composition information associated with waste types commonly occurring in the municipal solid waste stream. 8. The method of claim 7, wherein the collection of chemical composition information associated with waste types occurring in the municipal solid waste stream is a lookup table. 9. The method of claim 7, further comprising collecting data pertaining to a chemical composition of the mixed waste constituents of the first bunker and the second bunker. 10. The method of claim 9, wherein the data is certified for use by a third party. 11. The method of claim 1, further comprising combining the mixed waste constituents with an additive. 12. The method of claim 11, wherein the additive is at least one of a fat, oil, and grease. 13. The method of claim 11, wherein the additive is at least one of yard wastes and sludge. 14. The method of claim 11, wherein the additive is at least one of tires and crumb rubber. 15. The method of claim 11, wherein the additive is petroleum waste. 16. The method of claim 1, wherein the second bunker of waste constituents consists essentially of newsprint materials, the first bunker of waste constituents consists essentially of plastic materials, and the quantitative ratio is about 82 parts of waste constituents of the second bunker to about 18 parts of waste constituents of the first bunker. 17. The method of claim 1, wherein the second bunker of waste constituents consists essentially of magazine materials, the first bunker of waste constituents consists essentially of plastic materials, and the quantitative ratio is about 36 parts of waste constituents of the second bunker to about 64 parts of waste constituents of the first bunker. 18. The method of claim 1, wherein the second bunker of waste constituents consists essentially of paper materials, the first bunker of waste constituents consists essentially of textile materials, and the quantitative ratio is about 24.5 parts of waste constituents of the second bunker to about 75.5 parts of waste constituents of the first bunker. 19. The method of claim 1, wherein the second bunker of waste constituents consists essentially of newsprint materials, the first bunker of waste constituents consists essentially of plastic materials, and the quantitative ratio is about 91.8 parts of waste constituents of the second bunker to about 2.2 parts of waste constituents of the first bunker, and the method further comprising combining the mixed waste constituents with 6.0 parts yard wastes. 20. The method of claim 1, wherein the second bunker of waste constituents consists essentially of paper materials, the first bunker of waste constituents consists essentially of rubber materials, and the quantitative ratio is about 68.0 parts of waste constituents of the second bunker to about 32.0 parts of waste constituents of the first bunker. 21. The method of claim 1, wherein the first bunker of waste constituents consists essentially of rubber materials, the second bunker of waste constituents consists essentially of paper materials, and the quantitative ratio is about 80.0 parts of waste constituents of the first bunker to about 20.0 parts of waste constituents of the second bunker, and the method further comprising combining the mixed waste constituents with 13.0 parts water. 22. The method of claim 1, wherein determining the chemical composition of the waste constituents of the first bunker and/or determining the chemical composition of the waste constituents of the second bunker includes a measurement using thermo gravimetric analysis, prompt gamma neutron activation analysis (PGNAA), and/or dual-energy gamma attenuation.
