2. Wastewater treatment and heavy‑metal removal
Its alkalinity promotes metal hydroxide precipitation, helping remove metals such as lead, zinc, and copper from industrial wastewater streams.
| Parameter | Impact |
|---|---|
| pH adjustment | Moves pH into ideal removal range |
| Metal ions | Forms insoluble hydroxides |
| Sludge quality | Denser, easier to dewater |
3. Soil remediation and stabilization
Engineers use magnesium carbonate hydroxide to reduce soil acidity, immobilize heavy metals, and improve ground stability on industrial and brownfield sites.
- Lowers metal mobility and leaching
- Improves bearing capacity in soft soils
- Supports revegetation of treated sites
4. Data‑driven outlook for green uses to 2026
Demand in environmental sectors is expected to climb as decarbonization and circular‑economy projects scale. The chart shows projected growth by application segment.
