A study on the possibility of using samples of hydrolytic lignin chemically modified by alkaline and oxidative treatment as a binder in the production of wood composites was carried out. The functional composition and thermal stability of samples of initial and hydrolyzed lignin treated with alkali and hydrogen peroxide have been studied. It was found that in order to obtain fuel briquettes with high density and water resistance, it is advisable to use a binder from lignin treated with hydrogen peroxide. To obtain wood-based board materials with high bending strength and low water absorption, it is proposed to use hydrolytic lignin treated with alkali as a binder. By experimental and mathematical optimization, the parameters of the pressing process, which ensure the production of wood-based board materials with high physical and mechanical characteristics using hydrolytic lignin modified with NaOH as a binder, were determined
