Making an eco friendly board by using lignin- soy based natural adhesive

The wood composite industry in Malaysia comprises of 12 MDF and 10 particleboard plants with an installed capacity of about 5 million tons per year.The total production capacity is approx 2.5 million cubic ton.Most of the MDF boards are exported to US,Europe and Asian market.At present formaldehyde...
