Latest Patents

Kurt H Grunewald holds a patent for a lignin-based glue, which is substantially derived from chlorolignin. This glue is designed for gluing cellulose materials such as wood and particle board. Chlorolignin, a waste product from the cellulose industry, poses environmental challenges. Grunewald's patent addresses this issue by recovering chlorolignin through membrane filtering of waste liquor, effectively separating out compounds with a molecular weight lower than 1000-2000. The resulting glue can be used alone or mixed with common synthetic glues, including melamine-formaldehyde resins, fillers, and hardeners. Suitable hardeners for this glue include formaldehyde, paraldehyde, or ammonium chloride, and the chlorolignin can also be prepolymerized with these substances.
