An article, such as a pallet having a substantially flat deck member and a plurality of hollow legs projecting from the deck member, is molded as a one-piece unit from a papermill sludge. Dried, comminuted papermill sludge is blended with a fibrous reinforcing material, preferably a cellulosic material such as fibrous bark particles, and a resinous particle board binder, the resulting mixture of furnish is formed into a loosely fitted mat, and the mat is placed between dyes of a mold and press and compressed to substantially the desired shape under temperature and pressure conditions sufficient to bond the sludge and bark particles together.
