| 20110088858 | FIBROUS STRUCTURES COMPRISING NON-NATURALLY OCCURRING HARDWOOD PULP FIBERS - Fibrous structures employing non-naturally occurring hardwood pulp fibers, and more particularly, sanitary tissue products employing non-naturally occurring hardwood pulp fibers and methods for making same are provided. | 04-21-2011 |
| 20130213592 | MODIFICATION OF PLANT LIGNIN CONTENT - DNA constructs comprising a first DNA segment that corresponds to at least a portion of a gene in the monolignol biosynthetic pathway, a spacer DNA segment, and a second DNA segment that is complementary to the first DNA segment can be used to reduce or modulate the lignin content in plants. In some embodiments, DNA constructs comprise at a least a portion of a gene for 4CL, C3H, CCR, C4H or CCoAOMT. Vascular-preferred and constitutive promoters can be used to drive expression of the constructs. | 08-22-2013 |
| 162094000 | Bamboo | 1 |
| 20120180964 | COMPOSITIONS AND METHODS FOR BAMBOO PULPING - Disclosed herein are compositions, methods and systems for bamboo pulping. Bamboo biomass materials that are exclusively or largely uniform are used for bamboo pulping. In some embodiments, the bamboo biomass materials are derived from a pure stand or monoculture of bamboo. In some embodiments, the bamboo pure stand or monoculture is generated by micropropagation comprising meta-topolin or an analogue thereof and/or thidiazuron or an analogue thereof. | 07-19-2012 |

| 20090020246 | MANUFACTURING METHOD OF MECHANICAL PULP FROM CORNSTALK CELLULOSE - The present invention relates to a manufacturing method of mechanical pulp from stalks of corn, an annual plant, by adding a digesting agent and, prior to, during or following addition of the digesting agent, completely separating fibrous material from the cornstalks by mechanical refining. The method of the present invention comprises: (1) a first digesting process of adding 0.5-5 parts by weight of a digesting agent selected from caustic soda, sodium carbonate, sodium sulfite, sodium bisulfite, sodium sulfide, sodium oxide and sodium sulfate, or a digesting agent selected from a mixture of more than one of each to 100 parts by weight of crushed cornstalks, and of separating and digesting the solid substance after impregnating of the mixture; (2) a second digesting process of adding 5-10 parts by weight of more digesting agent to the digested solid substance obtained from the first digesting process, and of separating and digesting the solid substance after impregnating of the mixture; and a refining process of separating the solid substance to be digested and refining it mechanically, which is performed prior to, during or following the second digesting process. | 01-22-2009 |
| 20150041085 | PULP COMPOSITION - One aspect of the invention relates to a pulp composition made from agricultural renewable fibers (ARF) having low Kappa number with unexpected quality sufficient for papermaking (e.g., high strength parameters and high freeness). Another aspect of the invention relates to an ARF pulp having ISO brightness of 60% or higher, and unexpected quality sufficient for papermaking (e.g. high strength parameters and high freeness). Another aspect of the invention relates to a pulp composition made from a pulping process comprising using a high concentration of anthraquinone (AQ). The pulping process can use wood or nonwood fibers (e.g., bagasse and corn stover) to provide pulp having good paper-making quality. | 02-12-2015 |
| 162099000 | Non-wood | 3 |
| 20120152473 | FIBRE FURNISH - Fibre furnish for use in the manufacture of paper and paper-based products, the fibre furnish consisting essentially of plant petiole tissue, wherein substantially longitudinally aligned petiole fibres have been cut generally laterally to form fibres with a fibre length distribution such that at least 95% of the fibres have substantially the same predetermined fibre length. | 06-21-2012 |
| 20120247696 | PULPING PROCESS - The present invention relates to a process for forming a pulp mixture, the process comprising the steps of: a) providing a wood material and a first liquor, b) treating the wood material in the first liquor in order to release wood fibers, c1) introducing an agricultural crop/residue before or during the treatment of the wood material, and during the treatment deriving a first fraction comprising hemicellulose from the agricultural crop/residue, and/or c2) introducing a suspension of a first fraction comprising hemicellulose and a residue liquor derived from agricultural crop/residue by a liquor treatment, the introduction being done before, during or after the treatment of the wood material. The invention further relates to a pulp mixture comprising 1-30% originating from agricultural crop/residue and 70-99% originating from wood material. The pulp mixture comprises non-wood hemicellulose and at least part of the non-wood hemicellulose is sorbed on the wood fibers. | 10-04-2012 |
| 20140374040 | PROCESS FOR THE PRODUCTION OF AN INTERMEDIATE PRODUCT INTENDED FOR THE PRODUCTION OF ETHANOL AND FOR THE PRODUCTION OF LIGNIN - A process for producing from a lignocellulosic raw material of (i) an intermediate product that is intended for the production of ethanol, containing polysaccharides, cellulose and hemicelluloses, and (ii) a product containing lignin in an aqueous solution without sulfur residue, this lignin could be precipitated. The process includes a step of pulping the raw material in an extruder at a temperature of between 60° C. and 180° C. and in the presence of a quantity of water that represents between 200% and 450% of the mass of said raw material and in the presence of a strong base at a concentration of between 0.5% and 4% relative to the volume of water. | 12-25-2014 |
