Pollutants in the air, globally rising temperatures, climate change – man, nature and the atmosphere are increasingly suffering and protecting the environment is becoming ever more important. Sustainable solutions competence in many fields. Our contribution is analysis and appraisal know-how provided by engineers, chemists and physicists. And it is the experience of biologists when dealing with eco-systems such as the oceans. And it is even the noses of test persons when they smell something fishy. We inspect and analyse projects, products and processes, we measures, develop and certify throughout entire life cycles - from the consultation phase, the systems construction all the way to the potential disposal.
