摘要： A process for the production of a shaped article from paper sludge which comprises depositing a layer of an aqueous slurry of the sludge and controlling the water content of the layer by applied pressure and drying so as to produce a coherent agglomerated layer having a degree of wet strength and a water content of from about 15 to 30% by weight based on the total weight of the layer, and then forming the layer under pressure with drying to produce a shaped article.

摘要： A process for the production of a shaped article from paper sludge which comprises depositing a layer of an aqueous slurry of the sludge and controlling the water content of the slurry by applied pressure so as to produce a coherent agglomerated layer having a degree of wet strength, and a water content of from 40 to 85% by weight based on the total weight of the layer and forming the layer under pressure with drying to produce a shaped article.
