Degussa AG

Degussa AG, originally founded in 1873 as Deutsche Gold- und Silber-Scheideanstalt vormals Roessler (German Gold and Silver Refinery, formerly Roessler) in Frankfurt am Main, began as a precious metals refinery. Over time, it expanded into a major player in the chemical industry, producing specialty chemicals, industrial chemicals, performance materials, coatings, and products for health, nutrition, and construction.

Through mergers, including with Hüls AG in 1999 to form Degussa-Hüls AG and with SKW Trostberg AG in 2001, it became Germany's third-largest chemicals company and a global leader in specialty chemicals. In 2006, RAG acquired Degussa AG, and in 2007, its operations were integrated into Evonik Industries AG, where they form the core of the chemicals business area.

Degussa operated production sites worldwide, including in the US (e.g., Mobile, Alabama), focusing on innovative solutions like silica products (AEROSIL®), carbon black, and more, serving industries such as automotive, pharmaceuticals, and personal care.
