The present invention provides a pulp product (e.g., paper) comprising cellulose and nanocellulose, wherein the nanocellulose is derived from the cellulose in a mechanical and/or chemical step that is separate from the main pulping process. The pulping process may be thermomechanical pulping or hydrothermal-mechanical pulping, for example. The pulp product is stronger and smoother with the presence of the nanocellulose. The nanocellulose further can function as a retention aid, for a step of forming the pulp product (e.g., in a paper machine). Other embodiments provide a corrugated medium pulp composition comprising cellulose pulp and nanocellulose, wherein the nanocellulose includes cellulose nanofibrils and/or cellulose nanocrystals and the nanocellulose may be hydrophobic. The nanocellulose improves the strength properties of the corrugated medium. In some embodiments, the cellulose pulp is a GreenBox+® pulp and the nanocellulose is derived from the AVAP® process.

This invention discloses method for feeding Hermetia illucens and used as for preparing composite material of puparium, which comprises the following steps: S1, dry Hermetia illucens pupariums and grind them into powdery, S2, adding powdery of Hermetia illucens pupariums into sodium hydroxide aqueous solution, stirring, separating and filtering, S3, adding the pupariums into hydrochloric acid solution, stirring, separating and filtering; S4, placing the pupariums into sodium hydroxide aqueous solution, stirring, separating and filtering; S5, drying the pupariums, and screening out the granular pretreated powder of the Hermetia illucens pupariums. The invention also disclose preparation method of composite material and thin film of Hermetia illucens pupariums and antibacterial and antimildew additive. The method can effectively improve the yield of chitosan in Hermetia illucens pupariums, and the prepared pupariums powder can be used for preparing polymer composite fibers and thin films of the Hermetia illucens pupariums, thus, the antibacterial effect is greatly improved. A new antibacterial and antimycotic additive can be obtained by compounding the powder of Hermetia illucens pupariums with the powder of oyster shell.

The present invention is directed to a process for the production of thermally stabilized agglomerated lignin, which avoids melting and/or significant foaming during subsequent thermal processing. The process comprises the steps of providing agglomerated lignin and heating the agglomerated lignin to obtain thermally stabilized agglomerated lignin. The thermally stabilized lignin can be further processed to a carbon enriched material.

The invention relates to a method for obtaining cellulose fibres from fibrous biomass, in which: the biomass is first subjected to thermo-pressure hydrolysis, preferably with steam explosion, in a thermo-pressure hydrolysis plant, and then separation of the fibrous sludge obtained from the thermo-pressure hydrolysis plant is carried out in at least one separation plant, wherein a press cake of cellulose fibres, preferably with a dry material content of over 20%, preferably of over 25%, and a filtrate of flowable, solids-rich thin sludge are obtained, and wherein the thin sludge is fed to a biogas plant as a fermentation substrate to obtain biogas. The invention also relates to a plant for carrying out this method.
