Abstract: The invention provides protein adhesives and methods of making and using such adhesives. One type of protein adhesive described herein contains lignin and ground plant meal or an isolated polypeptide composition obtained from plant biomass. Other types of protein adhesives described herein contain a plant protein composition and either a hydroxyaromatic/aldehyde, urea/aldehyde, or amine/aldehyde component.

Abstract: Delignification of biomass consisting of plants containing lignin is done by utilizing an amino compound in an aqueous solution or emulsion to produce water soluble amino lignin and non-soluble amino lignin cellulose which are utilized to produce adhesives and resins for use to produce wood composites and carbohydrate production.

Abstract: Methods are disclosed for preparing lignin from lignocellulosic biomass using rapid full or partial pressure reduction to separate and pulverize the lignin without fouling the equipment and with improved energy recovery.

Abstract: The present invention provides a processed biodegradable article having excellent water resistance and rigidity, which can be used as a food container, and a biodegradable composition required to produce the processed biodegradable article comprising 15-75% by mass starch, 5-50% by mass protein, 3-50% by mass cellulose fiber, 0.5-20% by mass polyphenols such as pyrogallol and gallic acid, and 0-5% by mass sodium chloride.

Abstract: Method for making lignocellulosic composites by adhering lignocellulosic substrates together. A first variant of the method involves using an adhesive composition that comprises a reaction product of (i) first ingredient selected from a soy protein or lignin and (ii) at least one substantially formaldehyde-free curing agent that includes at least one amine, amide, imine, imide, or nitrogen-containing heterocyclic functional group that can react with at least one functional group of the soy protein. A second variant of the method involves using an adhesive composition that comprises a reaction product of (i) a protein or lignin, (ii) a first compound that includes at least one amine, amide, imine, imide or nitrogen-containing heterocyclic functional group that can react with at least one functional group of the protein and (iii) a curing agent.

Abstract: A first variant of an adhesive composition for making a lignocellulosic composite includes soy protein and/or lignin; at least one substantially formaldehyde-free curing agent that includes at least one amine, amide, imine, imide, or nitrogen-containing heterocyclic functional group that can react with at least one functional group of the soy protein; and at least one compound selected from a boron compound, a group IA oxide or hydroxide, or a group IIA oxide or hydroxide. A second variant of an adhesive composition includes a first component selected from soy protein and/or lignin; and at least one substantially formaldehyde-free curing agent selected from a reaction product of epichlorohydrin with ethylenediamine, a reaction product of epichlorohydrin with bis-hexamethylenetriamine, or a reaction product of epichlorohydrin with hexamethylenediamine.

Abstract: Disclosed is disposable tableware which is completely degradable under environmental conditions without environmental contamination. The disposable tableware is prepared using environmentally friendly, completely degradable materials without additional chemical additives while maintaining the shape and function of general disposable tableware so that it is completely degraded under environmental conditions, thus not causing environmental contamination and problems associated with waste disposal such as separation from other wastes. Also, the present invention discloses a method of manufacturing such disposable tableware. The disposable tableware is prepared by compression-molding a composition including 1–30 wt % of crop residues, 1–30 wt % of corn flour, 1–10 wt % of paper mulberry bark, 1–10 wt % of a moss and 30–96 wt % of a grain flour mixture as the remaining part.

Abstract: There are disclosed a functional glue in which the crushed ginkgo (leaves) and paulownia (leaves) materials are mixed with rice glue or barley and wheat glue at a desired ratio, thereby providing a mothproofing function, an antibacterial function and a moisture proofing function, and a fabricating method thereof. The method of fabricating a functional glue mixed with crushed ginkgo (leaves) and paulownia (leaves) materials, comprises steps of: filling the crushed ginkgo (leaves) and paulownia (leaves) materials in a crusher, respectively or all together so as to crush the crushed ginkgo (leaves) and paulownia (leaves) materials; and putting each of the crushed materials or all of them in a stirrer along with rice glue, or barley glue and wheat glue so as to fairly stir the crushed material and the glue.

Abstract: The present invention provides adhesive and binder compositions comprising a potato peel product characterized on a dry solids basis by at least 30% starch, at least 5% protein and at least 2% fibers.
