Advancements in Laser Technology and AI Drive Growth in the Circular Economy

The Fraunhofer Institute for Laser Technology ILT in Aachen, Germany is at the forefront of revolutionizing the recycling industry with its innovative laser-induced breakdown spectroscopy (LIBS) technology. This cutting-edge technology is enabling the identification of reusable raw materials in waste streams with unprecedented precision and speed.

As the world moves towards a circular economy, the demand for sensor-based processes that can automatically and accurately identify recyclable materials is increasing. The Fraunhofer ILT’s LIBS technology is playing a crucial role in closing material cycles and reducing downcycling, where materials lose their original value during the recycling process.

With LIBS, the institute is able to conduct highly efficient and differentiated analyses of valuable materials in waste streams. By using high-energy laser pulses to create plasma and analyze the chemical composition of materials, LIBS allows for real-time identification of elements in various materials, whether solid, liquid, or gas.

Dr. Cord Fricke-Begemann and his team at Fraunhofer ILT are leading the charge in developing inline processes based on LIBS technology. Their work is paving the way for the unmixed recovery of metals from electronic waste and scrap, ensuring the efficient reuse of valuable materials without downcycling.

LIBS technology is particularly beneficial for complex material compositions, such as electronic waste and end-of-life vehicles, where accurate determination and separation of material fractions are essential for one-to-one recycling. By automating the sorting process and enabling the identification of full material value, LIBS is revolutionizing the recycling industry and contributing to the establishment of truly closed material flows.

Overall, the Fraunhofer ILT’s LIBS technology is not only enhancing the efficiency and cost-effectiveness of recycling processes but also ensuring higher purity and value retention in the recycling of metals and alloys. With their groundbreaking work, the institute is driving the transition towards a more sustainable and resource-efficient future.
