This list features a selection of the largest chemical and manufacturing companies in Austria. Many are significant employers, with ALPLA Group, a global plastic packaging producer, employing 23,000 people, and RHI Magnesita, a leader in refractory products, employing 12,000. Other prominent firms include OMV, focused on sustainable fuels and chemicals, and wienerberger, a provider of building solutions. Greiner specializes in plastics and foam solutions, while Borealis focuses on sustainable polyolefin solutions.
A notable pattern among these companies is their long-standing presence, with several founded in the 19th century, such as RHI Magnesita (1834), wienerberger (1819), and Greiner (1868). This indicates a mature industrial landscape. While many are headquartered in Vienna, there's also a distribution across other Austrian cities like Hard, Kremsmünster, and Linz, suggesting a broader industrial base beyond the capital.

How this list is built
Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 12, 2026.
