Environment and Safety

Our Service

Processes in the industry can be made more precise, efficient and safe with laser measuring technology. Lasers can be used to identify, monitor or recycle materials at high throughput rates, in which, for example, geometrical and spectroscopic measurements can be used and combined. Fraunhofer ILT develops laser-based methods for material analysis, measuring and testing technology in the field of environment and safety. One focus is on industrial applications of laser-induced breakdown spectrometry (LIBS) in automated measurement processes. In the context of Industry 4.0, inline control of intermediate and end products is becoming increasingly important.

The spectroscopic measurement processes can be used for the inline and offline analysis of gases, dust emissions and for the detection of pollutants and safety-relevant substances, or for the analysis and classification of sludge and wastewater. Laser-based analysis opens up further applications for material recycling or to verify metals in production.

For example, in the field of recycling, laser-based measuring processes are ideal for automated sorting processes. Metals, ceramics, glasses, slag, or raw materials can be identified very quickly and sorted by type. This makes it possible, for example, to reuse metal alloys in an energy-saving and environmentally friendly manner and to reclaim rare valuable materials such as technology metals from electronic devices that are no longer used.

The range of services offered includes feasibility studies, the development of application-specific, laser-based measuring methods, the integration of systems into industrial processing technology or special systems as well as individual consultation.
