Adhesives. Adhesives can be considered as coatings between two surfaces. The classic adhesives were water-susceptible animal and vegetable glues obtained from hides, blood, and starch. Adhesion may be defined as the process that occurs when a solid and movable material (usually in a liquid or solid form) are brought together to form an interface, and the surface energies of the two substances are transformed into the energy of the interface. 

The common vegetable glues are based on either starch or cellulose. Unmodified starch dispersed in water is used to form paper pastes but a large proportion is now used in modified forms such as dextrin. Cellulose-based glues are produced by reacting hydroxyl groups present in the polymer chain with different reagents to form a variety of adhesives. 

Omnivores The ultimate survival strategy is to be able to eat nearly anything—a strategy favored by cockroaches, earwigs, and other pests. These species feed on all kinds of animal and vegetable materials, including soap, starch, and glue. 

There is a wide diversity of commercial adhesives available to the retail trade and for industrial applications. Synthetic adhesives have tended to replace animal- and vegetable-based glues, such as casein and starch types.

Processes and products developed to produce industrial materials from renewable resources have been too numerous to record here. For competitive reasons — supply of raw materials and technical and economic considerations — some of the products have varied widely in industrial use. Major U.S. industrial consumption of renewable resources have recently included oils and fats (animal and vegetable) industrial alcohol (wheat, corn, grain sorghum) fibers (cotton lint, flax, hides and skins) paper (forest products) isolated proteins (milk casein, animal glues, soybean, corn) turpentine and rosin (naval stores) and other chemicals (monosodiiim glutamate--wheat starch and dextrin—corn lactose—milk molasses and pulp residues --sugarcane and beet tannin lecithin pectin furfural). 

Natural animal (beeswax, casein), vegetable (gum, wax, dextrin, starch) and mineral- (amber, paraffin, asphalt) based glues. Commonly low strength applications such as paper, cardboard (packaging) and wood.
