Description

Any lightweight, porous solid material derived from biological material. Naturally occurring materials that have foam-like structures are numerous: wood, cork, sponge, fungi, honeycombs, cancellous bone, horseshoe crab shells, toucan beaks, antlers, etc. The vascular texture of these structures provide energy absorption and decreased weight. Often the material have a rigid exterior covering the foamed interior. Synthetic foams from biological materials, such as soy, wheat gluten, and cellulose, are also called biofoams or biobased foams. Biobased foams often mimic the cellular structure of wood and they are being used in packaging and insulation as substitutes for polystyrene or polyurethane. These porous, lightweight materials typically manufactured using cellulose fibers dispersed in a foaming agent or gel such as cellulose ester, or methyl cellulose. The biobased foams should be recyclable with cardboard. Cellulose foams exhibit antimicrobial properties, mechanical anisotropy, and high thermal insulation. Some alternatives are using wheat gluten for the gel formation in order to produce flame-retardant materials. Other bio-foams used starch, soy, gluten, polylactic acid (PLA) or polyglycol alginate (PGA) as their base material

-A biobased foam that mimic the cellular structure of wood.  Cellulose-based foams are lightweight materials typically manufactured using cellulose fibers dispersed in a foaming agent or gel such as cellulose ester or methyl cellulose.  The cellulose-based foams should be recyclable with cardboard. These cellulose foams exhibit antimicrobial properties, mechanical anisotropy, and high thermal insulation.
