%X The sludge generated in the paper recycling industries presents characteristics of a fibrous mass of brown color, being classified as residue II A ¨C no inert. Nowadays, the companies are looking for alternatives for reuse the sludge as inputs in other processes, with the intention to avoid or to reduce environmental liabilities.Thus, this work was the studies of the construction, operation and monitoring of a windrow composting, as well as the sizing of bed dryers, filter press and centrifuges for the sludge¡¯s treatment and its disposal in landfill. Finally, it was concluded that composting was presented as a good alternative for reuse of this material when applied in consortium with pruning and weeding wastes. Physical treatments that require less land available, such as filter presses and centrifuges, which speed up the drainage, resulting in compact and sophisticated units from the point of view of operation and maintenance, they can also be employed.
