Creosote was used for decades to preserve wood. It was highly effective, but tar oil was banned throughout the EU in 2023. An exception exists in certain countries for railway sleepers and telecommunications masts.
Peter Müller switched to modern, chrome-free impregnation processes at an early stage. Our old tar oil plant was completely dismantled and replaced by a modern, energy-efficient and sustainable autoclave (pressure vessel). Our Möderscheid site now meets the highest standards and offers high-performance contract impregnation for wood processing companies, thanks to a new operating licence and extensive investments in technology and the environment.
