CELLULOSE POWDER, USE THEREOF, AND TABLETS
The present invention provides a cellulose powder containing an alkali-soluble substance capable of dissolving in 17.5% by mass of aqueous sodium hydroxide solution, the content of the alkali-soluble substance being 32% by mass or more and 44% by mass or less with respect to the total mass of the cellulose powder, the use thereof, and tablets using the same.
DISSOLVABLE THREAD AND ARTICLE CONTAINING SAME
A recyclable thread or yarn having a dissolvable fiber and an insoluble fiber is provided and incorporated into a woven article, garment or textile. The dissolvable fiber and the insoluble fiber are twisted to form the thread or yarn. The dissolvable fiber may be a synthetic water soluble polymer and may dissolve in water at between 60° C. and 100° C. The insoluble fiber may be cotton such as extra-long staple (ELS) cotton or Supima cotton. A process for recycling a woven article, garment or textile made with the recyclable thread or yarn is also provided. The process for recycling a woven article, garment or textile made with the recyclable thread or yarn includes subjecting the woven article, garment or textile in water to a condition to cause said dissolvable fiber to lose long range order to form a slurry or solution.
METHOD FOR PREPARING LOW-COST FULLY-BIODEGRADABLE PLANT FIBER STARCH TABLEWARE
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.

A method for preparing a treated cellulosic material comprising: providing a cellulosic material; a first treatment protocol comprising impregnating the cellulosic material with a polymer, the polymer comprising a water-soluble polyol; and a second treatment protocol comprising impregnating the cellulosic material with a modifying agent, the modifying agent comprising a hydrophobic polyalkylene polyol.
FRACTIONATION AND DEPOLYMERISATION OF LIGNOCELLULOSIC MATERIAL
Lignocellulose constitutes an alluring renewable feedstock for the production of bio-based chemicals. This contribution demonstrates for the first time a chemocatalytic biorefinery concept that produces three separate product fractions of valuable product families at high yield and purity from lignocellulosic biomass; the product families, merely comprising of stable products, are (i) a lignin oil enriched with high contents of lignin-derived (mono)phenolics, (ii) essentially humin (furanic oligomers)-free hemicellulose-derived polyols, and (iii) a cellulose pulp. This is achieved by processing biomass in a close to equivolumetric mixture of an alcohol (such as n-butanol) and water at elevated temperature, in the presence of a metal catalyst and hydrogen. During this one-pot fractionation process, the hot liquor disentangles the polymeric biomass and depolymerises lignin and hemicellulose, while the catalyst and reductive environment are essential to accumulate and target stable products at high yield (such as phenolics and polyols, respectively). The process is particularly industrially relevant because its overcomes difficult and complex separation protocols, at place in classic biorefinery technology; the process foresees simple product recuperation in one process step into the three fractions; the solid carbohydrate pulp (mainly cellulose) is retrieved upon filtration, while phase separation of n-butanol and water occurs below 125° C., offering a facile and effective strategy to isolate lignin-derived phenolics, present in the alcohol (such as n-butanol phase) from polyols, present in the aqueous phase at the same time. The three resulting product streams provide a versatile platform for down-stream conversion towards added-value bio-based chemicals.
