Abstract
Distiller's Grain (DG) based bio-adhesives consisting of DG biomass, crosslinking agents, and fillers are described as substitutes for formaldehyde based wood glue for making wood panels. Algal bio-adhesives consisting of algal biomass, crosslinking agents, and fillers are described as substitutes for formaldehyde based glue for making wood panels. Processes for preparing such DG based bio-adhesives and algal bio-adhesives are provided, comprising the steps of: combining DG biomass or algal material with a cross-linking agent and inorganic fillers to form a blend; micronization or homogenization of the blend to obtain powdery material; and mixing the powdery material with additional water to form a bio-adhesive.
