About Hamburger Containerboard Trostberg

185 employees,

thereof five trainees,

produce 140,000 tons of paper per year.

Tradition, modernity and with a clear goal in sight

The origins of Hamburger Rieger started in Pitten, Austria, in 1853. Wilhelm Hamburger founded the factory there. Almost 60 years later, in 1912, Johann Rieger started producing mill board and cardboard in Trostberg. The development of white testliner paper continued to advance over the decades and with the takeover by the Austrian W. Hamburger AG in 1989.

We have an obligation to continue the entrepreneurial vision of the two founding fathers and their successors and develop our company in a sustainable manner for the future. We place emphasis on “tradition” (our experience and system of shared values), as well as on “modernity” (strength through innovation, new products and processes, and modern machinery and equipment). We are shaped by this symbiosis and our fascination for paper. We embrace the declared corporate goal of 4 million tonnes of paper by 2030.
