The process developed by UMaine researchers eliminates the use of formaldehyde as a binding agent, replacing it with a CNF slurry. The resulting product tests higher for fracture toughness and sequesters carbon and oxygen into the building product for its life span — typically decades.The UMaine inventor is professor of chemical and biomedical engineering Doug Bousfield.
