Where is Borregaard?
The production facilities is located at the Borregaard production site in Sarpsborg, Norway. The company also produces diphenols at its plant in Ravenna, Italy.
What does LignoTech make?
The venture, named LignoTech Florida (LTF), will serve the growing global demand for natural lignin-based products. Lignin, a natural component of wood, is a co-product of RYAM’s sulphite cellulose manufacturing process.
What is Borresperse?
Product Description Borresperse CA-SA is a purified grade calcium lignosulphonate product with low insoluble content and with near neutral pH. Typical application: As plasticizer or water reducing admixture for good grade concrete and mortar.
What is lignin in wood?
Lignin is one of the main components of trees or plants, jointly with the cellulose and the hemicellulose. Constituting around 30% of the dry mass of wood, lignin give trees their rigidity but also makes them water resistant and degradation resistant.
Where are lignins found?
Lignin is found in the middle lamella, as well as in the secondary cell wall of xylem vessels and the fibers that strengthen plants. It is also found in epidermal and occasionally hypodermal cell walls of some plants.
Do herbaceous plants have lignin?
Herbaceous plants do not produce perennializing above ground structures using lignin, which is a complex phenolic polymer deposited in the secondary cell wall of all vascular plants.
Can water pass through Lignified cell walls?
Endodermal cell walls are partially lignified to prevent passive movement along the apoplast (the cell wall space), thereby forcing all water and solutes to pass through the living endodermal cell cytoplasm where transit can be controlled.
Where is lignin found in trees?
Lignin fills the spaces in the cell wall between cellulose, hemicellulose, and pectin components, especially in vascular and support tissues: xylem tracheids, vessel elements and sclereid cells. Lignin plays a crucial part in conducting water and aqueous nutrients in plant stems.
