From Hazard to Resource: Turning Fly Ash into Value
Fly ash—a fine byproduct of coal combustion—poses serious risks due to its content of heavy metals like arsenic, cadmium, and lead, as well as silica particles that can cause respiratory issues such as silicosis. Environmental and health impacts range from water contamination to long-term illness.
Heyl Patterson’s thermal processing solutions transform this hazardous byproduct into high-quality, safe materials through efficient drying and de-carbonizing techniques.
Why Fly Ash Is Dangerous
- Releases toxic metals into air, water, and soil
- Poses health risks: respiratory issues, cancer, silicosis
- Historical disasters underline the urgency of safe handling
How Processing Makes Fly Ash Useful
- Drying & De-Carbonizing
- Removes moisture and combustible carbon residues
- Beneficiation
- Produces a safe, high-quality product for reuse
- Reuse in Construction & Industry
- As partial cement replacement—improving strength and lowering CO₂ emissions
- Applications: concrete, bricks, ceramics, soil stabilizers
