For us, sustainability means thinking ahead and making a positive contribution as a company. We do this by acting responsibly in environmental, social and economic terms.
We generate electricity at our sites using photovoltaic systems and aim to use as much of it as possible on-site through efficient energy consumption. In 2025, our photovoltaic systems generated a total of 490 MWh. Charging points for our electric fleet vehicles are available at both sites.
Our products are well-known in the market for their long service life and need to be replaced less frequently. Through continuous development, our products also help reduce emissions in use by preventing leaks, conserving resources and minimising environmental impact across their life cycle.
We are currently supporting our customers through the transformation from traditional to renewable energies. As a pioneer in the field of deep geothermal energy and hydrogen, we were there from the start and still are.
The members of our Hartmann nature and environmental protection group (NASCH) are actively engaged in sustainable projects in and around the Hartmann company.
Our know-how is our most important resource. That is why we place great emphasis on in-house apprenticeships and ongoing training of our employees. Our specialists of tomorrow are today’s apprentices, whom we aim to retain within the company after their apprenticeship.
The collaboration with regional suppliers and partners simplifies not only transport links but also strengthens the domestic economy.
Engineered & made in Germany – this approach and our high-quality products has made our third-generation family-run company succeed in global markets.
To maintain our growth trajectory and secure jobs for the future, we plan for the long term. We operate across a range of sectors—traditionally in oil and gas and the (petro)chemical industry, and increasingly in renewable energy such as geothermal and hydrogen. Drawing on our experience, we help shape emerging markets in our areas of expertise and support their development proactively.
In our R&D department we research and develop innovative solutions on a daily basis which secures our long-term competitive advantages.
Sustainable action is imperative if we are to offer subsequent generations a world in which there is room for ideas, advancement and life. For this reason we scrutinise our actions in all areas and in so doing initiate new, sustainable projects. Stay tuned!
