Abstract:
Methods to control and suppress odor in papermaking sludge are described. One method involves admixing sludge from a papermaking process and cyclodextrin to provide treated sludge with the cyclodextrin present in an effective amount to control odors in the treated sludge. The deodorized sludge may be used as a component of resin-wood composite products, such as composite decking materials, walls, flooring, casting forms, and the like.
