A biodegradable adhesive for use in at least one chosen from glue lap, case and carton seal, slower speed carton seal and bookbinding, the biodegradable adhesive including at least one chosen from: TABLE-US-00001 % (Parts) Water: 35-50 Defoamer: .3-.8 Gelatin: 25-35 Preservative: .2-.5 Glycerin: 7-15 Epsom Salt: 10-20 Vanilla Extract: <1 Total Parts: 100% and Water: 33-45 Defoamer: .3-.8 Gelatin: 35-45 Glycerin: 15-27 Preservative: .2-.5 Vanilla Extract: <1 Total: 100%.

The present disclosure presents improved polymer compositions, such as GelMA polymer compositions. In certain embodiments, the improved polymer compositions can be used as a soft-tissue adhesive for use in sealing, repairing and/or treating injuries, defects, or diseases in the soft tissue of a subject. In certain embodiments, the improved polymer compositions are hydrogels which can comprise gelatin methacryloyl (i.e., GelMA) or polymerically crosslinked derivatives thereof.

A method of preventing soil erosion in, among areas, seaside locations, includes drilling holes in the ground and filling the holes with a mixture of the soil and gelatin, and then curing the mixture in situ to form a barrier against soil erosion.

The invention is directed to a method for preparing a polymer derived from an animal protein, such as in a feedstock derived from animal by-products. The method involves hydrolyzing proteins present in a feedstock to obtain hydrolyzed proteins, wherein hydrolysis is conducted under conditions sufficient to digest the proteins and destroy pathogens; extracting a protein fraction from the hydrolyzed proteins; and treating the protein fraction with a crosslinking reagent to form the polymer. The crosslinking reagents may include epoxies. The polymer may be further processed to form a thermoset plastic. The polymer may be used as an adhesive, or in the preparation of a natural fiber composite material.

An adhesive composition is disclosed including buffering and pH adjusting agents, a binder protein, an alkali lignin, and a cationic curing agent. The adhesive composition is capable of being tailored for the purpose of making particle board materials of varying degrees, by virtue of modifying the compositional makeup of the adhesive composition. The resulting particle board is free of the conventional chemicals that are present in conventional particle boards, such as formaldehyde. The result is an all-natural, biodegradable, renewable particle board material that can replace conventional materials with a fraction of the environmental impact. Additionally, the material burns much cleaner than conventional materials, so particle board burn pellets can be made from the compositions disclosed herein.
