Oyster Shell Calcination Process
Marine Resource Valorization Tech
- Calcined at 1,000°C+ to remove toxins and stabilize shells
- High-temp calcination removes pathogens and impurities
- Calcined shells become calcium-rich material
Oyster shells, once treated as marine waste, are transformed into eco-friendly resources through high-temperature calcination.
This process not only eliminates waste but also adds value by converting it into industrial-grade material, paving the way for applications such as fertilizers, livestock feed additives, and sustainable materials.
