Treatment of wood chips for MDF manufacture with addition of laccase. a Energy consumed during defibering of wood chips at different conditions: (i) without compression screw: raw material without immersion (dark yellow), control with 120′ immersion + 20′ steaming (dark blue) and laccase plus 120′ immersion + 20′ steaming (dark green); or (ii) with compression screw: raw material without immersion (light yellow), control with 60 immersion + 10′ steaming (light blue) and laccase plus 60′ immersion + 10′ steaming (light green). b Internal bond as a function of density in MDF produced with fibres obtained applying enzymatic treatment with (white circles) or without compression screw (white triangles). Controls with and without compression screw are depicted as black circles and black triangles, respectively. c Swelling in water as a function of density of MDF produced with fibres obtained applying same conditions shown in a
