Environmental protection at RETORTE

As a specialised company, RETORTE GmbH supplies worldwide markets in the glass, animal feed, solar and pharmaceutical industries with high-quality selenium products such as high-purity selenium, selenium alloys, sodium selenite and trace element premixes. 

RETORTE GmbH Selenium Chemicals & Metals is located in Röthenbach an der Pegnitz, about 10 km east of Nürnberg. The task of the company within the group of companies is the further processing and marketing of selenium, which is a by-product of the copper production process. A significant proportion of the world's annual selenium production is processed at this site in Röthenbach. 

Intelligently networked cycles ensure the best possible use of the valuable raw material selenium and by-products are integrated into the cycle. A variety of measures are taken to keep emissions as low as possible and ensure a high level of production safety. In recent years, the wastewater treatment processes have been optimised - as a result, a reduction in the selenium load discharged into the Pegnitz River has been achieved. Furthermore, the site ensures the protection and remediation of existing contaminated sites through technical and financial investments.
