Applying laser-induced breakdown spectroscopy (LIBS) has proven to be a game-changer, providing solutions to such relevant issues. Avantes is a leading provider of advanced spectrometers specialized for aluminum recycling processes. With decades of experience and a commitment to innovation, Avantes offers a range of spectrometer solutions created to optimize recycling operations and contribute to the sustainable circular economy.
Addressing Key Challenges in Aluminum Recycling Through LIBS Technology
Aluminum recycling presents multifaceted challenges, ranging from efficient alloy sorting to quality maintenance and purity of recycled materials.
Material recovery facilities (MRFs) must process huge amounts of aluminum scrap while accurately identifying and separating different metal grades. Conventional methods fail to meet these requirements, leading to inefficiencies and compromised quality.
Avantes’ advanced spectrometers, which come with LIBS technology, provide a complete solution to these challenges. LIBS technology facilitates quick chemical analysis of metals using a multi-step process. A laser pulse is pointed at the material's surface, which heats it by thousands of degrees and generates localized plasma. Once cooled, this plasma releases visible and invisible light, which is discovered and analyzed in a spectrometer to determine the metal’s elemental composition.1,2,3
The efficiency of LIBS technology allows for in-line sorting abilities, with Avantes’ compact spectrometers enabling recycling facilities to reach a remarkable degree of precision when identifying and segregating aluminum alloys. This streamlines operations and enhances the overall efficiency of MRFs, laying the road for optimized recycling processes.
