Clean wood includes wood that is untreated, unstained and unpainted such as: construction lumber, pallets, plywood, OSB, particle board (also known as particleboard, low-density fiberboard (LDF), and chipboard), and branches.

Wood that is, or has ever been, pressure treated, stained, or painted, regardless of age or weathering, is not recyclable and should be disposed of as garbage. Railroad ties, which are treated with creosote, must be properly disposed - contact the designated C&D waste transfer facilities.
