Since 1934, the name RETHMANN has represented reliable services, customer-oriented action and forward-looking ideas. The family business is internationally successful and operates in the water management and recycling branches, logistics and bio-industry.
Josef Rethmann laid the first foundations for the success of the family business in 1934. He acquired a rail freight forwarding company and a haulage firm that was responsible, among other things, for the disposal of ashes from households in Selm. After acquiring a call for tender, this commission was extended over the entire city in 1959, and therefore became a foundation for the REMONDIS Group. In 1977, the service spectrum of what is now SARIA Bio-Industries AG was extended for the first time with the takeover of Gebrüder Schaap KG. The logistics sector of the Group was further strengthened in 1998 with the acquisition of Rhenus AG & Co. Since then, the RETHMANN family business has united three company branches under one roof, companies which are characterised by innovative as well as forward-looking concepts.
