ABSTRACT:
A method of producing synthetic resins from waste products containing lignin derivatives and sugars, especially waste liquors from cellulose pulp manufacture, is disclosed. The synthetic resins thus produced are especially utilizable as binders in chipboard, plywood, mineral wool slabs and the like. The method comprises treating the waste product in a first step so as to convert a substantial portion of the sugars contained therein into furfural derivatives. In a second step said furfural derivatives are condensed with the lignin to form a synthetic resin.
