While naturally occurring proteins can sequester critical raw materials, they are typically inefficient and not optimized for industrial use. Cambrium leverages precision fermentation and advanced AI-powered protein engineering to overcome these limitations. We can engineer proteins to efficiently extract previously unrecoverable concentrations of critical metals, transforming e-waste recycling. Just as potassium cyanide revolutionized gold mining in the 1880s, Cambrium’s proteins represent a paradigm shift in material extraction.
