Once collected in disposal containers, spent catalysts can undergo several processes:
1. Recycling: Many spent catalysts contain precious metals like platinum, palladium, and rhodium, which can be recovered and reused. 2. Incineration: Some spent catalysts are incinerated to break down hazardous components. 3. Landfilling: As a last resort, spent catalysts that cannot be recycled or incinerated are sent to hazardous waste landfills.
