We work at the intersection of metal recovery, pollutant stabilization, and CO2 mineralization to produce high-quality secondary raw materials (SCMs) from complex ashes, slags, and dusts. While developing our separation process for incinerator bottom ash, we encountered a well-known but poorly understood issue: The antimony paradox. When CO2 mineralization is applied to ashes, it can unintentionally increase antimony release in water. A process intended to improve environment

Did you know? Most precious metals and REEs in the world occur as fine particles, sometimes even dust-sized. Wastes are no exception. Gold. Silver. Ruthenium. Neodymium. These SEM–BSE–EDS images (incineration bottom ash) reveal micron-scale concentrations of high-value elements, invisible to the naked eye. 🔍 SEM-EDS, BSE imaging, ICP-MS A few backscattered electrons, the right analytical workflow… and the metals speak for themselves. The real questions are: are they recovera

Viewed from the outside, bottom ash just looks like a pile of dirty scraps. 🔬 But under the microscope, an entire crystalline world reveals itself. Take a look at their rapid transformation during CO₂ mineralization. See how cool these morphologies are? At the top:  • needle-like ettringite (Ca₆Al₂(SO₄)₃(OH)₁₂·26H₂O)  • hexagonal hydrocalumite (Ca₄Al₂(OH)₁₂Cl₂·4H₂O) As soon as they are mixed with water and CO₂, these minerals transform into carbonates, forming rhombohedral c

Over the past two months alone, we have received 100+ samples of alkaline wastes, with many more on the way. Ashes. Coal fly ashes. Metallurgical slags. Dusts. Biomass residues. Concrete and demolition materials. All are or have been under active investigation to scale up next-generation recycling and CO₂ mineralization solutions. What is particularly striking is the shift in momentum. The industry has been far more responsive than we could have anticipated just one year ago,
