Permeate is a part of the stream generated in the ultrafiltration process. This stream could be utilized due to its composition in low molecular compounds. In this work, different combinations have been used to study the use of ultrafiltration permeate as a preliminary step in the pulp and paper production. The results showed that the use of ultrafiltration permeate, obtained from the black liquor of olive tree pruning fractionation, as cooking liquor instead of the preliminary step is an excellent option, with yields of 35.6% and physical properties of paper sheets similar to those obtained by the use of green traditional liquor (0.599 kN/g burst index and 1.076 mNm2/g tear index).
