Nouryon's xanthate collectors (ROCS2Na) selectively coat sulfide mineral surfaces — making copper, zinc, and lead ores hydrophobic so they attach to air bubbles in froth flotation. The first step in every battery's metal supply chain.

Veolia's ammonium recovery from wastewater — struvite (MgNH4PO4·6H2O) crystallization — turns sewage into slow-release fertilizer. Phosphorus chemistry recovering a critical nutrient from waste.

Carbon Engineering's DAC process sprays KOH solution into air — CO2 reacts to form K2CO3, then causticization with lime (CaO) releases pure CO2 and regenerates KOH. The chemical loop that pulls carbon from sky.
