## Company history
### Foundation and first achievements

The company was founded in Dessau: around Easter 1859, master locksmith Gottfried Polysius opened a workshop in Dessau with an apprentice and laid the foundations for today's company with his locksmith's shop and the manufacture of safes. On May 23, 1870, he founded G. Polysius iron foundery and engineering factory, which established itself in the then-young building materials industry with self-designed and powerful mills. Besides money cabinets, the company also produced drains and vibrating screens.
In addition to agricultural machinery, Polysius also produced grain mills, brewery and distillery equipment. He was particularly involved in the up-and-coming beet sugar industry. From then on, Polysius specialized in crushing and processing machines. After Polysius' death, his sons Otto and Max Polysius successfully continued the company. The construction of cement plants became particularly important. In 1893, the company exhibited at the World's Fair in Chicago. 1898 saw the design and manufacture of the first rotary cement kiln in Europe. This was followed in 1912 by the construction of the Jesarbruch plant near Nienburg (Saale) for the Sächsisch-Thüringische Portland-Cement-Fabrik Prüssing & Co. KGaA.
In the late 1920s, Otto Lellep invented the LEPOL process. This revolutionised conventional cement production, significantly improving the burning process in the rotary kiln and reducing fuel consumption by a third.

### During World War II

The president of ThyssenKrupp AG, Alfried Krupp von Bohlen und Halbach, was tried and convicted for the use of slave labor and crimes against humanity. Krupp had insisted on the use of forced labour even when the German military suggested that some work should be performed by free German workers for security reasons.

### Development after the war

After the end of the Second World War, Polysius started up again in Dessau in 1946. At the same time, Bernd Helming and Curt Prüssing, a son-in-law of Max Polysius, founded Westpol GmbH in Neubeckum, which was renamed Polysius GmbH three years later. The company became the driving force behind the revival of Polysius' business in the west. The new office building was designed that the offices could easily be converted into apartments if the up-and-coming company failed. Prüssing and Bernd Helming remained on the Management Board even after the later conversion of the GmbH into a stock corporation. The Dessau factory was expropriated by the Russian administration in 1946 and later renamed VEB Cement plant construction. Just 10 years after the new start, Polysius employed 600 people in Germany and 100 abroad.
In 1951, the first complete cement plant was delivered to Syria. In order to remain competitive, the company was forced to install ever larger plants. As the value of individual orders increased, the total number of orders placed worldwide steadily decreased. In addition, the demand for complete plants resulted in an unusually high capital commitment and entailed a variety of technological and commercial risks.
The owners of Polysius realized that the financial demands on the company would sooner or later exceed the possibilities of a family business and therefore brought in the Essen-based Fried. Krupp GmbH as a shareholder.
In 1971, Essener Fried. Krupp GmbH acquired a majority shareholding in Polysius.

### Integration into the ThyssenKrupp Group

In 1992, Krupp Polysius was integrated into the Krupp Plant engineering division - a group structure of Fried. Krupp AG Hoesch-Krupp. In 1999, 140 years after the company was founded, it merged with the Thyssen Group to form ThyssenKrupp in what was one of Germany's first hostile takeovers. Polysius is now part of the international ThyssenKrupp Technologies division.
Acquisitions strengthened Polysius in the lime kiln (Maerz AG in Zurich) and services (AC Equipment Corp., USA) sectors. In October 2009, the 150th anniversary of the company was celebrated with three days of festivities in Neubeckum.

### Business Area: thyssenkrupp Industrial Solutions

In 2014, the two previously independent plant engineering companies thyssenkrupp Uhde and Thyssenkrupp Resource Technologies merged to form thyssenkrupp Industrial Solutions, headquartered in Essen. The company offers chemical, refinery and industrial plants as well as associated services such as planning, maintenance and training.
As of May 31, 2023, the business area was dissolved, which led to the renaming of thyssenkrupp Industrial Solutions GmbH into two independent companies: thyssenkrupp Polysius GmbH and thyssenkrupp Uhde GmbH.

### New business segment: Decarbon Technologies

In September 2023, the thyssenkrupp Polysius, thyssenkrupp Uhde, thyssenkrupp Rothe Erde (Bearings business unit) and thyssenkrupp Nucera business units were merged under the umbrella of the newly created Decarbon Technologies segment.
With the introduction of the new segment, thyssenkrupp is positioning itself as a leading technology company for the energy transition. The company's comprehensive competencies for the green transformation will be made fully visible.
