E-waste recycling organizationsAbout electronic waste recovery
Most of the work on Halo sorts a mixed scrap stream, identifying material by its spectrum through XRF, laser breakdown, X-ray diffraction or hyperspectral imaging, or by vision and machine learning. A smaller set recovers the material itself, from spent battery packs and from the rare earths held in electronic scrap. On Halo it spans four groups, including sorting by spectroscopy, sorting by vision and learning, and recovering critical materials.
Stage of development. Work on electronic waste recovery on Halo comes mostly from companies. 35% of the solutions are in market. Co-development and licensing are the usual partnering routes, and about 25% of the solutions that state terms offer sponsored research.
Three trends in e-waste recycling solutions on Halo
Recovery chemistry for batteries and rare earths. Recovery work is moving past sorting to getting the material back. Hydrometallurgical processing returns the metals in spent electric-vehicle batteries to industry (Primobius), and an acid-free, low-temperature route recovers lithium and graphite for new electrodes (tozero). Engineered microbes extract rare earths from electronic scrap and separate them element by element (Cornell University).
Every physics gets tried. X-ray fluorescence, laser-induced breakdown spectroscopy, powder X-ray diffraction, hyperspectral imaging, X-ray transmission, RGB vision, tactile sensing, and machine learning over several of these at once. One system combines four modalities on a single robot. No single signal identifies every material, which is why the multi-sensor approaches keep appearing.
The model learns on the operator's own stream. Actively learned segmentation and classification, deep learning trained on ferrous imagery, high-speed vision with AI in the loop. Scrap composition varies by region, supplier and season, so a model trained centrally is worth less than one that adapts to the material arriving at a particular yard.

Frequently asked questions
What are e-waste recycling solutions?
Electronic waste recovery covers identifying and separating the materials in a discarded device or a mixed scrap stream. It spans sorting by spectroscopy, sorting by vision and machine learning, and the chemistry that recovers a critical metal once separated. Recyclers, smelters and metal traders are the buyers. On Halo the work leans toward sorting by spectroscopy, sorting by vision and learning, and recovering critical materials.
