Impregnation of timber is one of the biggest sources of heavy metal pollution in Europe. SIBLARCH aims to develop Siberian larch as an environmentally sound alternative to impregnated timber in the Northern Periphery. The three main issues under investigation in the project are: 1.

Evaluate Siberian larch family tests in Scandinavia, Finland, Russia and Iceland The project will be performed in cooperation with saw mill industries and wood industries in Iceland, Norway, Finland, Sweden and North West Russia.
