Abstract One-layer particle boards with addition of particles of waste paper were manufactured. Two sorts of waste paper (mixed waste paper and waste paper bags) and two glues (urea-formaldehyde resin – UF and melamine-urea-formaldehyde one – MUF) were applied in the process. Properties of the boards (bending strength, modulus of elasticity, perpendicular tensile strength and thickness swelling after 24 h soaking in water) were examined. As a result it was found that waste paper can be a supplementary addition in the production of particleboards. Boards had sufficient properties if maximum content of waste paper should not exceed 50% (with the MUF resin) and 30% (with the UF resin).
