Saxon newspaper 17/4/2002Impregnation plant develops the first environment-friendly tar oil of the world
Ten years after the privatization, the impregnation plant in Wülknitz surprises the world with a sensation. From now on, environment-friendly tar oil will preserve wood from rot and insects. The swiss chemicals group Lonza wants to develop the new impregnation substance Creosote after an idea out of Wülknitz.
Tar and ecology. Normally these two terms don't go together. Highly alarmed, environmentalists point out that still structural timber and wooden poles are impregnated with hard coal tar oil. This liquid doesn't stay forever in the wood. On the contrary it evaporates under the sunlight and, while doing so, produces carcinogenic gas. Above that there's the risk that the tar will seep into the ground water.
An alternative to conventional agents is therefore badly needed.
That's why the responsible people at Wülknitz thought about limiting these risks, perhaps even banning them. Manager Tilo Vogel and his son-in-law Oliver Arlt had the idea to develop an environment-friendly tar oil. The basic concept was: the oil should be more intensely compounded with the wood and preserve its natural colour. And indeed, the first sleepers built into the company site have such an light colour as if they had never seen any impregnation boiler. Compared to them the conventional sleepers next to them are black, an oil film is shimmering on the surface. "We're convinced that now we have a real alternative to conventional tar oil", says Tilo Vogel. But the Wülknitzers never could have realized their idea on their own. Therefore they searched for suitable partners and found them.The chemicals group Lonza in Basles which plans to put the environment-friendly impregnation substance on the market. At the international impregnation conference in Istanbul, Turkey, the first presentation of Creosote EC 265 amazed the experts and the competitors. Big U.S. and Canadian timber processing companies had been already interested, says Vogel. The Europeans stay reserved. This could change soon, if the EU bans tar oil. "The bureaucratic machines in Brussels are running already" the Wülknitzer knows. "I hope that if these gentlemen enact a law against tar, our new impregnation substance is going to be accepted on the market." Becoming the German market leader doesn't occur to him. Stay reasonable is his motto. Anyway, field tests with Creosote are far from being completed. It's true that several poles are already forming a test network near Neubrandenburg and Darmstadt, but it will take three years to see how long the magic potion will last.
But one thing is for certain, the Wülknitzers have again made new friends concerning ecology. Several years ago already, they completely replaced the polluted soil of their site. It cost them seven millions euro and was the most expensive rehabilitation in the Free State of Saxonia so far.
