Ash Removal

Ash Roll-Off Container 

What began as 10 cubic yards of waste ends up as about 1 cubic yard of ash.  Bottom ash is processed through a water-filled quench tank to reduce temperature and eliminate dust.  Fly ash is stored in a silo before being processed through a conditioning mixer that converts the dry dust into a moist soil-like consistency.  Both bottom ash and fly ash are conveyed to, and deposited in, roll-off containers. These containers are loaded on a truck, covered, and taken to the ash monofill (an ash-only cell) at the Kalmar Landfill where the ash is deposited in specially constructed cells.
