Abstract
The invention concerns the waste liquor from the chemical-thermal pulping of fibre boards and particle boards containing bonding agents. The waste liquor is produced through a procedure in which fibre boards and wood particle boards are first chopped into shreds and, in a subsequent step, pulped according to a chemical-thermal procedure which dissolves the wood structure. The liquid remaining after the separation of the cellulose is retained as waste liquor and used as extender for wood adhesives.
Claims21
