Methods for making a lignocellulose composite product are provided. In one aspect, the method includes combining a plurality of lignocellulose substrates, calcium lignosulfonate, and a free radical precursor to produce a mixture, wherein the free radical precursor comprises an oxidant and a catalyst; and at least partially curing the mixture to produce the lignocellulose composite product. In another aspect, the method includes combining a plurality of lignocellulose substrates, calcium lignosulfonate, a free radical precursor, and a polyphenolic material, an unsaturated compound, or both a polyphenolic material and an unsaturated compound to produce a mixture; and at least partially curing the mixture to produce the lignocellulose composite product. In another aspect, the method includes combining a plurality of lignocellulose substrates, calcium lignosulfonate, a free radical precursor, and an unsaturated compound to produce a mixture; and at least partially curing the mixture to produce the lignocellulose composite product. Des procédés de fabrication de produits composites lignocellulosiques peuvent comprendre l'association d'une pluralité de substrats lignocellulosiques, du lignosulfonate de calcium, et d'un précurseur de radicaux libres pour produire un mélange. Le précurseur de radicaux libres peut comprendre un oxydant et un catalyseur. Le mélange peut être au moins partiellement durci pour produire un produit composite lignocellulosique.
