Our milestones

The most important stages in our firm’s history
1885 A Weimar stone masonry firm began to make polished window sills, wash basins, and tiles with interesting fossil inlays for indoor and outdoor purposes, using travertine (freshwater limestone) from the adjacent quarry. The process steps needed then—cracking, drying, sifting and calcinating—continue today as the foundation of our process engineering.
1946The industrial manufacture of limestone is urgently needed during the reconstruction period following World War. Large quantities of travertine are mined from the Ehringsdorf quarry and processed into very pure limestone using large shaft kilns and hydration facilities. A cable car system transports the limestone through the Ilmtal to the nearby railroad station.
1974Limestone manufacture is discontinued for economic reasons after a rich 90-year history.
1975The grounds of the former limestone works were acquired by the GDR state firm, VEB Zementanlagenbau Dessau, in order to conduct research and development work in the field of cement process engineering. For this purpose the first rotary kilns were erected, still found in our works. Many years of past research and development work for the manufacture of cement clinker and the use of industrial waste still shape our technical profile today.
1993

Following the re-unification of Germany, the SKET-institute is privatised and bought by the Deutsche Treuhandgesellschaft. Later that year the IBU-tec institute is founded, whose initial letters are retained in the present day company, which still remains focused on research and development in the area of thermal and process engineering.

2001The business was taken over by the present management board, developing steadily year by year.  There was continued growth in staff, financial resources and installed plant capacity. The year 2001 marked another milestone with the start of the first catalyst production using pulsation reactors at IBU-tec.
2008We succeeded in further development of the worldwide unique pulsation reactor technology. Optimisation of the reactor enabled for the first time a choice between oxidising, inert and reducing heated gas atmospheres for material treatment. The plant became especially suited for the manufacture of very fine and catalytic powders.
2011With a 38 % boost in sales IBU-tec, in the meantime registered AG, is able to build on the best business year (2008) in the company’s history.The whole company was awarded recertification in accordance with standard EN ISO 9001:2000, and went on to further improve its logistics facilities constructing a new warehouse and a staff car park with 75 spaces.
Todaythere are twelve rotary kilns, seven pulsation reactors and laboratories here. The number of employees rose from 20 at the beginning to more than 160 today. Since 2000 approximately EUR 31 million has been invested in infrastructure, ultra modern technologies and modern workplaces. With our research and production capacities for handling and refining of powders and granulates we occupy a niche not only throughout Germany but also internationally. In 2017 IBU-tec completed a successful IPO at the Frankfurt Stock Exchange. IBU-tec was the first IPO in the newly created segment “Scale”. On March the 30th 2017, we received our first share price.
