    Unfortunately, we had to shut down our production as of end of 2022. The Dimethyl Terephthalate production and the entire industrial site are on a stand-by mode effectively as of February 1st, 2023. We would like to thank all our customers, suppliers and partners for decades of good cooperation and regret not being able to continue it. Our best wishes for 2023 to all our business partners.



    Oxxynova arose from a previous company, Dynamit Nobel AG, and was Europe’s leading producer of DMT until December 31st, 2022 when production was shut-down. The company name is derived from the most important sub-process of DMT production, the oxidation of paraxylene, and also represented the innovative character of our production and logistics processes.


    One of the main reasons for the success of our business model is the optimisation of the logistics processes for our raw materials, paraxylene and methanol, and for the DMT we produce from them. This also includes return transport of the methanol recovered from processes involving our DMT at our customers’ premises.



    Oxxynova GmbH site is located in Steyerberg, which is between Hanover and Bremen near to the district town of Nienburg/Weser. Until the shut-down of its Dimethyl Terephthalate production as of December 31st, 2022, the plant was a major employer in the region.

    Liquid DMT has been produced here since 1977 and in solid form since 2013 to consistently high quality standards using the Witten-Katzschmann method – also known as the Dynamit Nobel method. From car seatbelts to tarpaulins, DMT (dimethyl terephthalate) is used to make all kinds of everyday items.
