The accumulation of wood extractives in paper mills (forming the so-called pitch deposits) result in low-quality pulp and blockages causing important economic losses as well as effluent toxicity. This proposal focuses on the pilot-scale development of environmentally-sound methods for pitch control during manufacture of selected pulps (spruce TMP and eucalypt TCF-bleached Kraft pulp) based on:
I) fungal strains selectively-removing compounds responsible for pitch deposition to be used for formulation of inoculate to treat wood;
ii) to use of new industrial enzymes (native or engineered proteins) for removing pitch compounds and optimised protocols for expression, fermentation and purification of these enzymes,
iii) suitable combination of the above treatments with improved physicochemical methods to remove pitch or decrease its disposability;
iv) analysis of advantages of the new processes in terms of control of pitch deposition, pulp and process parameters, and effluent treatment and toxicity; and
v) evaluation of the commercial interest of the of the(suite dossier)
