Lignin is an organic substance belonging to a group of aromatic alcohols. It is naturally produced by certain plants (especially woody plants and certain algal species). It is found in the secondary cell walls of plants where it serves as a binder for cellulose fibers and provides stiffness to the cell walls. it is present in wood primarily to provide structural support and protection against degradation by microorganisms. It fills the spaces in the cell wall particularly in xylem tracheids, vessel elements and sclereid cells. Since lignin is hydrophobic it assists in the efficient water transport across the vascular tissue. Ecologically, the importance of lignin is associated with the carbon cycle. It takes carbon from the atmosphere into the woody plant tissues and therefore acts as an important reserve of carbon in the form of humus as the plant tissue slowly decomposes.

Protobind KW is our speciality product with proven capability to be used in PF resin manufacturing process. This product, as a natural polyphenolic material obtained from woody plants, offers a bio-based alternative to fossil-based materials such as phenol. Our product can be used as a partial substitute for phenol used in PF resin production. The replacement degree can be flexible, depending on the layout and design of the available production process to produce lignin-based PF resin. However, thanks to intensive research work, plenty of modification methods are available to apply to ease and optimise the processes.
