September 25, 2025 - With the successful commissioning of a new
sulfuric acid plant in Worms, Germany, Röhm GmbH (Darmstadt, Germany) has
further reinforced its global production network. As the company’s largest
production site, Worms plays a strategically pivotal in the global network.
Röhm is the only global manufacturer of methyl methacrylate (MMA) and
polymethyl methacrylate (PMMA) with production sites in Europe, Asia and
North America. In recent years, Röhm had already made targeted investments
to strengthen this unique position, including significantly expanding PMMA
production capacities and constructing a state-of-the-art innovation center
at the Worms site. Last year, the company commissioned a new Plexiglas plant
in Worms. Now, after only one and a half years of construction, the
sulphuric acid plant has also been put into operation. Equipped with
state-of-the-art technology, it sets new standards in efficiency and makes a
significant contribution to strengthening the regional supply of MMA. The
plant replaces the previous facility, which was damaged by a fire at the end
of 2023. Sulfuric acid is a key precursor for the production of MMA – an
important basic chemical for customers in the automotive, construction and
medical technology industries and PMMA. “With the new sulfuric acid
plant, we are not only increasing supply security for our customers, but
also strengthening our value chain in the long term,” said COO Hans-Peter
Hauck at the inauguration ceremony. The construction project exemplifies
Röhm’s integrated production principle, which focuses on producing in the
region for the region. In doing so, Röhm offers its customers not only
regional proximity but also a high degree of delivery reliability and
planning security. The project also stands out for its excellent
occupational safety record. “The fact that we were able to implement the new
plant not only on time and within budget, but also in accordance with the
highest safety and quality standards, is an outstanding achievement,”
emphasized COO Hans-Peter Hauck. “My thanks go to the project team and all
the colleagues involved – your commitment and expertise are exemplary for
what makes our Worms site special: high-performance production, innovative
research and a strong team.”
May 5, 2010 - Germany-based Evonik is extending the shutdown of a
sulphuric acid plant in Worms, Germany, because of “unforeseen technical
problems”. April 28 2010 - During the scheduled plant revision unforeseen technical problems in the sulphuric acid plant occurred that will force Evonik Röhm GmbH to extend the shutdown by probably four weeks. As the sulphuric acid plant is an important part of Evonik´s Methacrylates Verbund this will clearly impact the availability of Evonik´s VISIOMER® methacrylate monomers like MMA, n-/i-BMA and specialty monomers as well as various PMMA downstream products. Within the next weeks these plants will run with substantially reduced rates. |
