abstract Pulp and paper industrial sector generates annually a large amount of residues. One of the major wastes is the sludge from the effluents primary treatment (PTS - primary treatment sludge). An attempt is made to substitute traditionally used celluloses long fibres by PTS (short fibres) in the fibrocement manufacture. Aiming the identification of all optimal amount, the behaviour of the fibrocement composite was Studied in function of the substitution content. Replacement amounts up to 100% were processed and relevant processing parameters like density, solids in suspension and mechanical strength were measured. Substitutions between 20 to 50% induce a good value of particles retention compared to the reference one. Furthermore, negligible reduction in strength (similar to 1-2 MPa) for those Substitution levels was verified. These fibrocement product features, important for processing and application, are not hindered by the incorporation of wastes.
