CELLULOSIC SUPERABSORBENT POLYMER FROM POST-CONSUMER TEXTILE WASTE

The present disclosure provides methods of preparing cellulosic superabsorbent polymer (SAP) using cellulose powder.

METHOD FOR PREPARING MODIFIED CELLULOSE AEROGEL FOR GLYCOPROTEIN SEPARATION

A method for preparing a modified cellulose aerogel for glycoprotein separation is provided. In this method, cellulose aerogel is employed as a substrate. The cellulose aerogel is known to have a three-dimensional network structure with extremely high porosity and specific surface area and extremely low density. So, by using the cellulose aerogel as a substrate, it is possible to provide the glycoproteins to be separated with more binding sites. PEI dendrimer has abundant functional groups and can easily be modified. By modifying the cellulose aerogel substrate with the PEI dendrimer, it is possible to improve the density of the phenylboronic acid bound to the substrate, thereby leading to higher affinity toward the glycoproteins to be separated.

A PROCESS FOR THE PREPARATION OF BIODEGRADABLE PLASTIC FILMS

A process for the manufacture of biodegradable plastic films in aqueous environment, starting from vegetal wastes in powder form is provided, without use in any steps of the process of chemical reagents and organic solvents that may leave harmful residues in the film, and without making use of operative conditions potentially compromising the environmental sustainability and an effortless scalability of the process.

DISSOLUTION OF OXIDIZED CELLULOSE

A process for dissolving modified cellulose is disclosed. The process includes contacting modified cellulose with a solvent in a mixture to form swelled modified cellulose and then contacting the mixture with a salt to dissolve the swelled modified cellulose.

Methods for producing a manure-derived bioplastic and bioproducts
11091564 · 2021-08-17 ·

The invention relates to the separation of manure in fractions and the treatment of said fractions in order to retrieve useful components to produce manure-derived bioplastic and other manure-derived bioproducts. The invention further relates to a method for producing composite (bio)plastic, and to a method for producing fibre from regenerated manure-derived cellulose. The methods include the steps of: flocculation treatment and a filtration treatment; pulping the manure-derived solid fractions; acetylation of the manure-derived dissolving-grade cellulose pulp with acetic anhydride and a catalyst; extracting fermentable components from the different fractions of the manure to produce monocarboxylic acids for use in the monocarboxylic acid carrier solution. Furthermore methods are disclosed for forming composite bioplastics with resin binding agents; and for spinning yarn from cellulose pulp.
