We take responsibility out of conviction

Our perception of ourselves requires us to be an integral part of society and to take our social duties seriously.

Strongly rooted in the location of Schwanau and the surrounding region, as a family-run business we are aware of our responsibility for people and the ecology. Our long-term and sustainable thinking is reflected in our support of education, the environment and society. Martin Herrenknecht leads the way with personal commitment as a driver in many areas.

Knowledge points the way to the future

Education & Science

Education and science are central to social and economic progress. That's why we not only champion the personal and professional development of our up to 180 trainees, but also financially support young talents outside the company for school and student education projects – both nationally and internationally.


acatech (German Academy of Science and Engineering) represents German science and engineering at home and abroad. The work academy sets itself the goal of supporting the transfer of knowledge between science and industry and encouraging the next generation in science and engineering. As a member of the acatech Senate, since 2014 Dr.-Ing. E.h. Martin Herrenknecht has advised the Academy in strategic matters.

Herrenknecht scholarships at universities

We financially support technical education at various colleges and universities. Among other things, we provide funding to students at Carolo Wilhelmina in Braunschweig (Brunswick), the Karlsruhe Institute of Technology, the Offenburg University of Applied Sciences and the RWTH Aachen for stays abroad, to study at foreign universities and for internships abroad on jobsites or in engineering offices. In addition, the founder and Chairman of the Board of Management Dr.-Ing. E.h. Martin Herrenknecht personally supports the ALS research chair at the Berlin Charité hospital.

Max Planck High School, Lahr

"High-tech in the classroom" – under this motto, Herrenknecht provides funds for the teaching of science and technology subjects at the Max Planck High School in Lahr. Martin Herrenknecht supports practically oriented teaching in physics, chemistry, biology and geography with 35,000 euros per year.  Since 2011 we have been co-organizers of the school's annual Engineer’s Day, giving young people an insight into technical careers.

In harmony with nature

Environment & Resources

As the market leader in mechanized tunnelling technology, we not only set new standards in terms of safety and efficiency, but also promote the responsible use of resources and the environment. Thus, our TBM remanufacturing operation is a groundbreaking and key contribution to more sustainability in the entire tunnel building industry.

Our technology has one goal: to create sustainable connections. Whether transport infrastructures for the transport of people and goods, efficient supply and disposal systems or pipelines – our sophisticated technologies and methods are designed to intervene in nature as little as possible.

In times of scarce fossil fuels and continuously rising energy prices, the demand for innovative technologies that reduce energy consumption is growing worldwide. We are therefore a member of the initiative "Energy Efficiency – Made in Germany", which was set up by the Federal Government as an export initiative for energy efficiency. Our products are developed in an energy-efficient and energy cost-saving way.

Our deep drilling rigs in the Exploration business area create major prerequisites for the targeted development and exploitation of new energy sources. With innovative technology and the funding of a chair for technical petrophysics in Karlsruhe, we are committed to the development of deep geothermal energy throughout Germany and Europe. Because geothermal energy is one of the most efficient renewables and, thanks to its permanent availability, is able to cover the base load in the electricity grid. 

At our headquarters in Schwanau, we have been using a shallow geothermal system for heating and cooling administrative buildings for many years. With this we generate 324,000 kilowatt hours of energy per year and save 31 tonnes of CO2 a year compared to conventional heating systems. Additionally, since 2005 and 2007 two photovoltaic systems on the roofs of the factory buildings have been producing around 251,000 kilowatt hours of electricity per year.

Remanufacturing proven premium technology

In our remanufacturing facility, after project completion we professionally rebuild proven machines and components for reuse. This opens up new potential for our industry and is economical, environmentally friendly and good for the carbon footprint of your construction project.
