Use of Cyclodextrins For Odor Control In Papermaking Sludges, and Deodorized Sludge and Products

摘要

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.
