Rethinking contaminated site remediation - with high-tech for sustainable restoration

Soil and water pollution caused by industry, contaminated sites or accidents poses serious challenges for the environment, people and infrastructure. We rely on modern remediation technologies that are not only effective but also environmentally friendly.

Remediation of contaminated sites as the key to sustainable development

Soil and water pollution are among the most pressing environmental problems of our time. Contamination from previous industrial use, accidents or improper disposal not only jeopardises ecosystems, but also the health of humans and animals - often for decades. The responsibility to remove these contaminated sites is not only a technical challenge, but also a social responsibility.

With Cornelsen we see the remediation of contaminated sites not as an isolated measure, but as a holistic process for the restoration of natural resources. With our many years of experience and in-depth technological expertise, we develop innovative remediation solutions that combine environmental compatibility, effectiveness and economic efficiency.

Our aim is to support the treatment of contaminated soils, groundwater and surface waters with systems that make these environments safe, usable and liveable again — for present and future generations.

We supply modern in-situ technologies, intelligent system monitoring, and customised processes for rent or purchase. Our offering includes complete remediation systems as well as the rental and sale of equipment from our large fleet of mobile units. All solutions can be seamlessly integrated into complex environments – even during ongoing operations or in sensitive protected areas.

Our projects range from acute emergency response to chemical accidents to the long-term remediation of former industrial sites. Whether urban neighbourhoods, industrial sites or water protection areas - we develop solutions that are geared to real needs and deliver measurable results.

Because a healthy environment is the basis for a healthy future. And we shape this future with technology, responsibility and conviction - every day.
