Infraserv Höchst

Infraserv Höchst (formally Infraserv GmbH & Co. Höchst KG) is a German industrial services company and site operator headquartered in Frankfurt am Main. It is best known as the operator of the Industriepark Höchst, a 460-hectare chemical and pharmaceutical industrial park that hosts around 90 companies and approximately 20,000 employees. The company emerged in 1997 from the site services of the former Hoechst AG and has since established itself as a leading site developer and provider of chemistry-related services. Infraserv Höchst offers a broad portfolio of services including energy supply, waste management, network operation, site services, occupational health and safety, environmental protection, facility management, laboratory services, logistics, education and process technology. Its customers include major chemical and pharmaceutical companies. The group generates annual revenue of approximately €1.4 billion and employs around 3,000 people, including 230 apprentices trained through its subsidiary Provadis. The company is privately held. Its general partner is Infraserv Verwaltungs-GmbH, a subsidiary of Celanese GmbH. The limited partnership shares are held by Clariant Group (32%), Sanofi-Aventis Deutschland (30%), Celanese Group (31.2%), Basell Polyolefine (3%) and Infraserv Logistics GmbH (3.8%). This ownership structure reflects the historical breakup of Hoechst AG into various successor companies. Infraserv Höchst operates primarily in Germany, with activities at several major industrial sites. The Industriepark Höchst is one of the largest chemical sites in Europe and benefits from excellent transport connections via road, rail, the Main river and nearby Frankfurt Airport. The company positions itself as a partner for companies in highly regulated environments, offering modular and integrated service packages up to complete site operation.

Infraserv Höchst traces its origins to 1863, when a small tar dye factory was founded in Höchst, at the time part of the Duchy of Nassau. This factory grew rapidly into one of Germany's largest chemical companies, Hoechst AG. Over the following decades, the site developed into a major chemical and pharmaceutical complex, and the town of Höchst became part of Frankfurt am Main. In 1997, following the restructuring and breakup of Hoechst AG, the site services division was spun off as Infraserv GmbH & Co. Höchst KG. The new company took over the operation and management of the industrial site, which was renamed Industriepark Höchst. Since then, Infraserv Höchst has established itself as a site operator and industrial services provider for the pharmaceutical, chemical and biotechnology industries. The company has continuously expanded its service portfolio. It now offers energy supply, waste management, network operation, site services, occupational health and safety, environmental protection, facility management, laboratory services, logistics, education and process technology. Through its subsidiaries, including Infraserv Höchst Prozesstechnik GmbH, Infraserv Logistics GmbH, Infraserv Netze GmbH, Provadis Partner für Bildung und Beratung GmbH, Infrasite Beteiligungs GmbH, Thermal Conversion Compo, Industriepark Höchst GmbH and KFT Chemieservice GmbH, the group covers a wide range of industrial services. Today, the Industriepark Höchst is one of Europe's largest chemical and pharmaceutical sites, hosting around 90 companies and approximately 20,000 employees. The site is optimally connected to international goods and financial flows via road, rail, the Main river and nearby Frankfurt Airport. Infraserv Höchst itself employs around 2,100 people, while the entire Infraserv Höchst Group has around 3,000 employees and 230 apprentices. The group's revenue in 2024 was approximately €1.4 billion. Investments in the site since 2000 total approximately €8.5 billion. Recent developments include the opening of Europe's largest e-fuels production plant, Ineratec's ERA ONE, at the Industriepark Höchst in June 2025, and the start of a Carbon Capture pilot plant. These projects reflect the site's ongoing transformation towards sustainable technologies.
