Rare-earth Elements and Critical Materials Extraction
A low-energy, cost-effective, and environmentally benign pathway to extract and recover high-value Rare-earth Elements (“REEs”) and Critical Materials (“CMs”) from municipal waste.
Residues from incinerated waste are selectively dissolved using acoustic energy to generate aqueous feedstocks. These feeds are then processed through a series of nanofiltration and electrolytic ultrafiltration separations to create REEs and CMs such as Yttrium (Y), Neodymium (Nd), Europium (Eu), Erbium (Er), Dysprosium (Dy) and Terbium (Tb)–– the planet’s rarest elements and the source of some of tomorrow’s more prescient environmental and geopolitical issues.
