The present invention relates to a method for producing a denatured cellulose fiber cake including carrying out a solid-liquid separation of a dispersion containing denatured cellulose fibers under the conditions of a centrifugal force of a centrifuge of 50 G or more and 600 G or less (step A). According to the present invention, a new method for producing a resin composition containing denatured cellulose fibers, and a new method for producing a denatured cellulose fiber cake, a shortened anionically denatured cellulose fiber cake, modified cellulose fibers, or fine cellulose fibers which can be used therefor can be provided.

The present invention relates to bio-based carbon foams, a method for their manufacturing and their use. The method comprises foaming a slurry of cellulose fibres to obtain a cellulose fibre foam, adding a biomass component to the foam, and carbonization of the biomass-cellulose fibre foam.

A method for recycling polyester from a polyester textile. The method comprises the steps of: providing said polyester textile soaked in a mixture comprising a solvent and a catalyst, providing and maintaining a temperature of said mixture comprising said polyester textile within a range of 80-240° C. during depolymerization of polyester in said polyester textile and wherein, in said step of providing said polyester textile soaked in said mixture, said catalyst of said mixture comprises calcium hydroxide. A catalyst may be used for depolymerization of polyester in a polyester textile, wherein the catalyst comprises calcium hydroxide. Natural fibers may b e recovered from a textile comprising polyester and natural fibers.

The present invention relates to a masterbatch composition comprising high concentration of biological entities having a polymer-degrading activity and uses thereof for manufacturing biodegradable plastic articles.

Provided herein are core-shell microcapsules useful for compartmentalizing biological molecules in solution. Also provided are processes for manufacturing core-shell microcapsules and methods for using core-shell microcapsules to compartmentalize and optionally process biological entities and molecules.

A method for separating a fraction of super-absorbent polymers (SAP) from post-consumer absorbent sanitary products, said post-consumer absorbent sanitary products further including at least one cellulose fraction and one plastic fraction. The method includes the steps of sterilizing the post-consumer absorbent sanitary products and treating said post-consumer absorbent sanitary products by immersion in a bath with an aqueous solution containing at least one oxidizing compound. The oxidizing compound is preferably selected from the group consisting of sodium persulfate, potassium persulfate, ammonium persulfate, potassium monopersulfate, and hydrogen peroxide; preferably hydrogen peroxide. The treatment by immersion allows cross-link cleavage and solubilizing of the SAP contained in said post-consumer absorbent sanitary products, and obtaining a suspension comprising i) a solid fraction and ii) a liquid fraction, wherein the liquid fraction comprises linear polyacrylate derived from the cross-link cleavage and solubilization of SAP.

Disclosed herein is a method for preparing a low-cost fully-biodegradable plant fiber starch tableware. A plant cellulose material containing dregs of Scutellaria baicalensis is modified to obtain a modified plant fiber starch blank. Konjac gum is subjected to pulverization and ultrafine pulverization to obtain a colloidal binder combined with a deacetylated konjac gum. The colloidal binder is mixed with the modified plant fiber starch blank to obtain a mixture. The mixture is subjected to foam molding in a forming mold to obtain the low-cost fully-biodegradable plant fiber starch tableware.

Ultra-stable aqueous foam comprises hydrophobic silica particles residing within bubbles in an aqueous solution of a hydrophilic polymer, a protein, or aqueous dispersible colloidal particles. The combination of the hydrophobic and hydrophilic components stabilizes the foam interfaces to result in long term stability of the foam. The foams can be crosslinked to stable monolithic foams and used for structural foams, coatings, and thermal insulating for construction.

A textile recycling method receives textile-waste-to-be-recycled, sorts the waste to isolate cellulose-containing articles from non-cellulose-containing articles, and re-sizes at least some of the cellulose-containing articles to create feedstock. The feedstock is processed in a cellulose solvent reactor, which has at least one ionic liquid. The ionic liquid dissolves intermolecular cellulose bonds of the feedstock to create a spinning dope. Cellulose fibers dissolved in the cellulose-bearing spinning dope solution are extruded in a cellulose coagulation bath reservoir to reconstitute at least some of the cellulose fibers, and the reconstituted fibers are wet-spun to form a continuous cellulose thread that is commercially indistinguishable from virgin fiber thread. Synthetic fiber material is vacuum-extracted or mechanically extracted from the cellulose-bearing solution and recycled into a continuous synthetic thread. Original color of textile-waste-to-be-recycled can be retained or removed, and new color can be added.
