The company was founded in 1948 on the premises of Ludwig Heller and VEB Metallwaren as a successor to the Leuchtstoffwerk Steinbach under the name Leuchtstoffwerk Bad Liebenstein in the city ​​of the same name as a state-owned company for the production of oscillator fluorescent materials. At the time it was founded, it was the only significant operation of its type in the Soviet occupation zone . The newly founded company was affiliated with the Association of People's Own Companies (VVB) Paper / Chemistry Thuringia. In 1951 the company began its own research and development activities.

In 1972, another facility was built in Breitungen / Werra , followed in 1980 by the construction of a factory for the production of color television phosphors and zinc sulfide , which was completed in 1984 and started operations. Two years later, the product portfolio was expanded to include specialty chemicals and three-band fluorescent materials (for energy-saving lamps ). When the state-owned companies were privatized in 1990 after the political change in the GDR, one looked in vain for a buyer for the fluorescent plant. In 1992 the Bad Liebenstein plant was closed and production was completely relocated to Breitungen. A year later the Leuchtstoffwerk Breitungen GmbH was founded. The company specialized in special phosphors and special pigments, and wrote several patents. From 1997 the product portfolio was again expanded to include special fluorescent materials, special pigments, color television fluorescent materials, LED fluorescent materials ( silicates ) as well as nitride and YAG fluorescent materials. In 1999, the factory acquired the production of color television phosphors from Philips in Eindhoven. 2002 the company was awarded the large SME Award of the Oskar Patzelt Foundation . The Breitungen phosphor factory was at times the third largest manufacturer of color television fluorescent materials.

The Breitungen fluorescent plant has been a subsidiary of the Austrian Treibacher Industrie AG and the Treibacher Industrieholding since 2012 .

Products

The product range includes a. Phosphors for lighting technology and LEDs, X-ray diagnostics , LPD technology. Pigments, such as fluorescent materials for use in paints and varnishes, textile and cellulose fibers, masterbatches and plastics as well as ceramics and coatings. Electroluminescent phosphors for advertising and backlighting. In addition, inorganic specialty chemicals and nano-pigments.

Environmental impact

After the Bad Liebenstein plant was closed, it was found that at the location, in the middle of the spa town's health resort district, the soil and groundwater are heavily contaminated with pollutants, especially cadmium . The Grumbach watercourse was also affected. In 2000, Thüringer Grundstückssanierungsgesellschaft mbH took over the industrial wasteland on behalf of the Free State of Thuringia and initiated measures to demolish the plant and clean up contaminated sites . Starting in 2003, the plant was demolished for two and a half years and around 35,000 t of contaminated soil and stream sediment were cleared. The renovation costs, which were borne by the state, amounted to around 4.2 million euros. Even today, the cadmium content in the topsoil is above the precautionary value, but below the value of the Federal Soil Protection Ordinance and, as a permanent soil observation area, is under constant surveillance by the Thuringian State Institute for Environment and Geology .

Production wastewater is discharged into the Werra at the Breitungen site to this day . In 2008, the Thuringian Ministry of Agriculture, Nature Conservation and the Environment, in response to a small question from MPs Frank Kuschel and Maik Nothnagel , announced that this was based on an unlimited use permit under water law for the discharge of sanitary, production and rainwater from 1988. In 1993, as the legal successor, the Leuchtstoffwerk Breitungen submitted an application for a new permit under water law to discharge their wastewater directly into the Werra.
