Almost half of Austria is covered by woods, thus making it one of the most well-forested countries in Europe, featuring a total forested surface of 4 million hectares. And the total forested surface and the wood capacities increase by approximately 4,000 hectares every year. This number equals the surface area of about 5,500 football fields, which means that the wood regrows faster than it is being harvested. The percentage of forested areas is even higher in Styria, where the headquarters and production facility of Rubner Holzindustrie is located: more than 60 %
The number of coniferous trees in our forests is at approx. 80 %, 60 % of which are spruce trees, thus making the spruce the most common tree type and the most important supplier of construction wood. We are a PEFC-certified company and buy only logs (silver fir, spruce) from sustainably managed forests from our suppliers. At their Rohrbach an der Lafnitz site, Rubner Holzindustrie uses 100 % of the logs to make glulam beams, solid construction timber, side cuts, and mill byproducts.
At our location in Rohrbach, Styria, we use some of the mill byproducts, more precisely, the bark, in our factory’s own biomass heating plant for thermal recovery. The thermal energy thus generated is used to dry the sawn timber we produce to the level requested by our customers. The remaining mill byproducts – the bark not used for our own products, the wood chips as well as the sawdust, and the planing chips – are sold.
