An omnibus process of pulping and bleaching lignocellulosic materials in which a charge of a lignocellulosic material is biopulped and/or water extracted prior to pulping and bleaching. The lignocellulosic material may be mechanically pulped and bleached in the presence of an enzyme that breaks lignin-carbohydrate complexes. The aqueous extract in embodiments including a water extract step is separated into acetic acid and hemicellulose sugar aqueous solutions.

1. A method of producing a paper product, the method comprising: (a) providing a charge of lignocellulosic material;(b) contacting the charge of lignocellulosic material with water, the water and charge of lignocellulosic material maintained at a temperature in the range of between about 130° C. and
1. A method of producing a paper product, the method comprising: (a) providing a charge of lignocellulosic material;(b) contacting the charge of lignocellulosic material with water, the water and charge of lignocellulosic material maintained at a temperature in the range of between about 130° C. and about 180° C. and lowering the pH to between about 3 and about 6.9 by producing acid from the reaction of the water and lignocellulosic material for a period in the range of between about 10 minutes and about 6 hours, wherein an aqueous extract and extracted lignocellulosic materials are obtained and wherein the acid comprises acetic acid;(c) pulping the extracted lignocellulosic materials to produce a pulp, wherein the pulp has a viscosity of greater than about 30 cP;(d) recovering hydrolyzate from the pulp;(e) contacting the pulp with at least one alkali;(f) mechanically refining the pulp; and(g) forming the paper product using the pulp. 2. The method of claim 1, wherein the paper product is a paperboard product. 3. The method of claim 2, wherein the paperboard product is selected from the group consisting of folding boxboard, kraft board, solid bleached board, container board, corrugated medium, a molded product and linerboard. 4. The method of claim 1, wherein the pulping step (c) is effectuated by a process selected from the group consisting of mechanical pulping, chemical pulping and a combination of mechanical and chemical pulping. 5. The pulp according to claim 1, wherein the pulp has a specific surface area between about 15,000 cm2/g and about 25,000 cm2/g. 6. The pulp according to claim 1, wherein the pulp has a specific volume between about 2.75 cm3/g and about 3.75 cm3/g. 7. The method of claim 1, wherein the water and charge of lignocellulosic material are maintained at a temperature in the range of between about 140° C. and about 180° C. 8. A method of producing a pulp, the method comprising: (a) providing a charge of lignocellulosic material;(b) contacting the charge of lignocellulosic material with water, the water and charge of lignocellulosic material maintained at a temperature in the range of between about 130° C. and about 180° C. and lowering the pH to between about 3 and about 6.9 by producing acid from the reaction of the water and lignocellulosic material for a period in the range of between about 10 minutes and about 6 hours, wherein an aqueous extract and extracted lignocellulosic materials are obtained and wherein the acid comprises acetic acid; and(c) pulping the extracted lignocellulosic materials to produce the pulp, wherein the pulp has a viscosity of greater than about 30 cP. 9. The pulp according to claim 8, wherein the pulp has a specific surface area between about 15,000 cm2/g and about 25,000 cm2/g. 10. The pulp according to claim 8, wherein the pulp has a specific volume between about 2.75 cm3/g and about 3.75 cm3/g. 11. The method of claim 8, wherein the water and charge of lignocellulosic material are maintained at a temperature in the range of between about 140° C. and about 180° C. 12. A method of producing a pulp, the method comprising: (a) providing a charge of lignocellulosic material;(b) contacting the charge of lignocellulosic material with water, the water and charge of lignocellulosic material maintained at a temperature in the range of between about 130° C. and about 180° C. and lowering the pH to between about 3 and about 6.9 by producing acid from the reaction of the water and lignocellulosic material for a period in the range of between about 10 minutes and about 6 hours, wherein an aqueous extract and extracted lignocellulosic materials are obtained and wherein the acid comprises acetic acid;(c) pulping the extracted lignocellulosic materials to produce the pulp; and(d) refining the pulp, wherein the pulp has a viscosity of greater than about 30 cP. 13. The method of claim 12, further comprising a step of forming a paper product with the pulp. 14. The method of claim 12, wherein the paper product is a paperboard product. 15. The method of claim 14, wherein the paperboard product is selected from the group consisting of folding boxboard, kraft board, solid bleached board, solid unbleached board, container board, corrugated medium, a molded product and linerboard. 16. The method of claim 12, wherein the pulping step (c) is effectuated by a process selected from the group consisting of mechanical pulping, chemical pulping and a combination of mechanical and chemical pulping. 17. The pulp according to claim 12, wherein the pulp has a specific surface area between about 15,000 cm2/g and about 25,000 cm2/g. 18. The pulp according to claim 12, wherein the pulp has a specific volume between about 2.75 cm3/g and about 3.75 cm3/g. 19. The method of claim 12, wherein the water and charge of lignocellulosic material are maintained at a temperature in the range of between about 140° C. and about 180° C.
