Results on enzymaatic deinking of paper pulps are shown. The process includes paper pulping, with an enzymatic cockail, followed by flotation and dewatering. Three different wastepaper samples were used and testd. The deiinking of the pulp was monitored by image analysis. Physical, mechanical and optical properties of pulp and paper were also determined. The obtained data revealed the effectiveness of the assayed enzyme preparation. Howeve,r enzyme use needs further optimixation as paper strength properties suffereed important alteration.
