Abstract
A process is described for the manufacture of tannin-bonded particle- and fiberboard wherein the binding of wood chips and fibers is accomplished by obtaining the formaldehyde necessary for the cross-linking of tannin by the hydrolytic decomposition of the binder present in old particle- or fiberboard. The formaldehyde obtained by hydrolytic decomposition is cross-linked with the tannin by high temperature and moisture during pressing.
