Alternative use of deinking sludge as a source of fibers in fiber-cement manufacture Blanco Suárez, María Ángeles Negro Álvarez, Carlos Manuel Fuente González, Elena de la Sánchez, Luis Miguel The present paper, contributing to solving two different problems related both to the chemical industry and the environment, is a feasibility study on the utilization of the deinking sludge (the most important waste from papermaking) as a raw material for fiber-cement manufacture, in which asbestos has been recently replaced by other fibers because of the hazard it induces. The results obtained show that the use of deinking sludge as a source of cellulose in fiber-cement manufacture is feasible and could improve product strength, if 5% of the virgin fibers are replaced by fibers and fines from the deinking sludge. It is also possible to replace up to 10% of the virgin fibers, with no loss in product strength. These results, if confirmed on a mill scale, would improve the economy of the process, as due to lower waste costs. 2023-06-20T09:25:56Z 2023-06-20T09:25:56Z 2008 journal article 0576-9787 https://hdl.handle.net/20.500.14352/49501 https://www.cellulosechemtechnol.ro/ eng PROLIPAPEL-CM (S-0505/AMB/0100) open access Romanian Academy
