In the last years non woody plants, and particularly agricultural residues, received an increasing attention as source of fibres for paper mills. Their cell walls allow an efficient biopulping by means of enzymes. By adopting our LINA process, the enzymes are produced efficiently by solid-state fermentation (SSF) of lignocellulosic materials (Giovannozzi Sermanni and Porri, 1989). Therefore an efficient biopulping has been set up , which can be applied also to waste papers, the main fibre source in countries where virgin papermaking pulps are not produced. This paper presents our results on enzyme effects on agricultural residues and waste papers for the preparation of pulps for paper mills.
