A resin system and methods of making resin system wherein lignosulfonate is added to urea-formaldehyde and melamine-urea-formaldehyde adhesives. Lignosulfonate is added to the resins which improves the performance characteristics of the adhesive while reducing environmental impact by consuming byproducts from other industrial processes. The resin system includes a urea-formaldehyde (UF) resin or melamine-urea-formaldehyde (MUF), prepared in at least two stages wherein the UF resin or MUF resin has a molar ratio (MR) of total moles formaldehyde to total moles urea plus, if present, the one or more melamine compounds of from about 0.25:1 to about 2.50:1, and wherein one or more lignosulfonate compounds are included in an amount of from about 0.1-30 wt. %, based on a total weight of the resin system, and wherein the resin system has a buffer capacity of 2-400 mL of 0.1 N HCl by the ATV Method for a period of time of at least about 20 days at 25° C.
