Abstract
The disposal of whey permeate (deproteinized whey/lactose) from the cheese industry represents a serious economic and environmental problem in the USA. The feasibility of replacing part of the phenol and formaldehyde in phenol-formaldehyde thermosetting resins by lactose/ lactose derivatives in the resin formulation has been explored. Results indicate that dilactosylurea and N-hydroxymethyl-N′-lactosylurea might be incorporated in the resin formulation without substantially affecting the wet shear strength of southern pine plywood bonded with these whey-modified resins. It appears that up to 50% (by weight) substitution of phenol by the modifier in the formulation can be accomplished before significant loss of the wet strength is observed.
