The binding agent in wood, lignin, is the raw material for Borregaard LignoTech.
Lignin is a natural polymer. The word 'lignin' is derived from the Latin word ‘lignum’, meaning wood. Lignin forms an essential part of the wood stems and takes part in transport of water and nutrients. It acts as an encrusting material and performs multiple functions that are essential the the life of the plant.
Lignin imparts rigidity to the cell walls and acts as a binder between wood cell walls, creating a composite material that is outstandingly resistant to compression and bending. Lignin is one of the most abundant organic polymers on earth, exceeded only by cellulose, constituting 30% of non-fossil organic carbon.
Lignosulphonates are branched natural polymers. Natural polymers are understood as polymers which are the result of a polymerisation process that has taken place in nature, independently of the process with which they have been extracted. Classified as a post-reacted natural polymer, lignosulphonates are classified as exempt from REACH registration.
Borregaard LignoTech’s range of lignin-based products serve as additives in a large number of industrial and commercial applications, and often directly displace petroleum-based products with a natural renewable solution.
Building on inherent qualities, and further enhanced by chemical modification, our lignin-based products offer a unique and desirable set of functions for the chemical industry in areas such as: concrete admixtures, pesticide dispersants, battery expanders, oil well drilling chemicals, emulsions, ceramics, road binders, by-pass proteins and animal feed pelleting additives.
