The philosophy behind GluGreen®
The first ideas about the GluGreen® development originate from 2003. By developing a technique for gluing green tropical hardwoods, a higher timber yield from the same area of sustainably managed forest would be possible. Making the gluing of green timber possible was essential for the philosophy since hardwood is often used without seasoning. The existing gluing techniques all make use of kiln-dried or air dried timber. Experiences with the gluing of green hardwood with conventional techniques were not successful. Therefore the development of a new technique was necessary.
Eventually, a consortium of companies and TNO was established. Both, hardwood importers with forest concessions in Africa and South-America as well as Mevo Houtindustrie (with broad experience with gluing of wood) participated in the consortium.
First, several tropical hardwoods and different techniques and glue types were tested in the state of the art TNO laboratories. Many tests and innovations, resulted in the GluGreen® Technology. GluGreen® is characterised by its high quality and reliable gluing. The principals can be used for glulam and finger-jonting; both were extensively tested (also outdoors).
For these new techniques (including the findings and principals) several worldwide patents have been applied (patent pending). These patents are for to the most important wood producing countries and are expected to be approved shortly.
GluGreen first focused on finger-jointed hardwoods, as there is a strong demand from this market. In the past few years, several pilot projects have been finalized, and resulted in satisfied GluGreen customers.
