RIGA ECOlogical – new Lignin based glue for RIGA Plywood
Latvijas Finieris has developed for its well known RIGA Birch Plywood a new Green Glue RIGA ECOlogical, where Bio-Based renewable Lignin is used as replacement of the traditional Fossil Phenol. This technological breakthrough, reached in cooperation with Stora Enso, World Leader in Chemical and Mechanical Forest Industry, is the most significant innovation in Plywood products gluing since many decades. The carbon footprint of RIGA Plywood is reduced from production to all its end-uses, offering to all RIGA customers a significant competitive advantage in the increasingly green business environment.
Results of Industrial production trials show that all technical properties of RIGA Plywood remain unchanged when the environmentally friendly glue RIGA ECOlogical is applied, containing Stora Enso Kraft lignin Lineo™. Of course, it’s only the beginning. Our aim is to develop completely fossil free plywood glue in a future, although there is still a lot of research work ahead to achieve that.
This is Lignin
All Woods contain 20-30% of Lignin, a polymeric substance which together with Cellulose forms the woody cell walls of trees and binds together the wood fibers and cells. This strong and rigid structure allows the trees to stand and grow upright.
Industrial Lignin is usually extracted from wood as a powderous by-product in chemical "Kraft" Pulp production. Still until the 2000’s, the main use of Lignin has been energy production by burning, with calorific values comparable to carbon.
Lignin is a recyclable and ecologically friendly product, abundantly available in the entire world in trees and plants. Therefore, it has recently become important subject to active research, to develop new and more sophisticated uses for it. This rising technological wave with most promising results belongs today to the World’s Megatrends. RIGA ECOlogical is one of them.
