Abstract: The present disclosure relates to cellulose nanomaterials made or derived from tobacco and methods for the production thereof. The tobacco-derived cellulose nanomaterials can be employed in various industrial applications such as film forming applications and solution thickening technologies. In particular, the disclosure is directed to methods for preparing tobacco-derived cellulose nanomaterials using less fibrillation cycles than in the production of wood pulp. The invention includes a method for preparing tobacco derived nanocellulose material comprising receiving a tobacco pulp in a dilute form such that the tobacco pulp is a tobacco pulp suspension with a consistency of less than about 5%; and mechanically fibrillating the tobacco pulp suspension to generate a tobacco derived nanocellulose material having at least one average particle size dimension in the range of about 1 nm to about 100 nm.

Abstract: The present invention relates to a process for treating textile-based materials, typically textile-based waste-materials, to prepare them for further use. The treatment includes two or more chemical and/or enzymatic treatment steps, including at least one alkaline treatment step, all intended to cause at least a partial dissolution of the textile-based material. Particularly, the process is used for the treatment of cotton-based waste materials.

Abstract: The present invention relates to a method of treating biomass, comprising providing a lignocellulosic biomass feedstock; contacting the biomass feedstock in a mixture, which is formed by the biomass, water and an alkaline agent, with an oxidizing agent at an elevated temperature; and continuing the contacting of the biomass feedstock with the oxidizing agent until a notable part of the lignin is solubilized. The step of providing the biomass feedstock comprises contacting a biomass raw-material containing cellulose, hemicellulose and lignin in an aqueous phase with an alkaline agent; continuing the contacting of the biomass with the alkaline agent until a significant portion of the hemicellulose is dissolved in the aqueous phase to provide a modified biomass; recovering the modified biomass; optionally opening the structure of the modified biomass by mechanical treatment; and using the modified biomass as a lignocellulosic biomass feedstock.

Abstract: A method of producing dissolving pulp from a recycled fibrous feedstock. The method comprises providing a fibrous material comprising cellulose, lignin and hemicellulose, said fibre source further having a lignin content of 0.1 to 7% lignin and an ash content of up to 3%; subjecting the fibrous material to an alkaline extraction at a temperature of about 0 to 25° C., to produce fibres having a reduced content of hemicellulose; subjecting the fibres thus obtained to a bleaching treatment carried out with oxidative chemical reagents in order to reduce the lignin content of the fibres; and recovering the fibres thus obtained. By means of the method, dissolving pulp can be produced from recycled paper and cardboard products.
