Pellets Production Using Sludge From Pulp Mill, 20IBBC Conference

The expansion of pulp and paper industry in last years has brought significant increase in the waste generation. The primary and secondary sludge represents major solid waste of pulp and paper mills. In order to avoid the disposal of the sludge in landfills, it has been evaluated better alternatives for its management. The production of pellets from sludge may be a viable option, because the pelletizing process densifies the residues producing a material with high heating value and better handling condition. The objective of this work was to use pure primary sludge and a mixture of primary and secondary sludge from the effluent treatment plant of a eucalyptus bleached kraft pulp mill for the production of pellets using a wet route process for energy purposes. The pellets from pure primary sludge (Pellets 1) and the mix of primary and secondary sludge (Pellets 2) presented satisfactory uniformity and good visual characteristics. Average bulk densities of 551 kg m-³ and 385 kg m-³ were observed for Pellets 1 and 2, respectively. Were observed pellets with viable characteristics and for energy production in the mill and a significant landfill disposal reduction, optimizing space and reducing costs for the industry.
