Fabrication of Medium Density Fibreboard from Enzyme Treated Rubber Wood (Hevea brasiliensis) Fibre and Modified Organosolv Lignin

Fabrication of Medium Density Fibreboard from Enzyme Treated Rubber Wood (Hevea brasiliensis) Fibre and Modified Organosolv Lignin

Lignin is considered as a potential substitute for formaldehyde based adhesive due to its phenolic based composition and huge availability. In the present work, rubber wood fibres were treated with the laccase enzyme to improve the fibre surface and to generate an active lignin solution. Lignin solu...
