Beneficial Uses for Recycled Waste-to-Energy Ash

Oct 19, 2016  In Pasco County, waste management officials changed its ash management approach to mix only enough bottom ash with fly ash — at a ratio of 25 precent bottom ash to 75 percent fly ash — to render the mixture non-hazardous. This new approach frees up 83 percent of the bottom ash to be reused as construction aggregates.

Bottom Ash - an overview ScienceDirect Topics

Bottom ash is the residue that is fused into heavy particles that drop out of the furnace gas stream (air and combustion gases). Table 10.3 presents the chemical composition properties of bottom ash. These particles are formed at the bottom of the furnace. Bottom ash consists of coarser and heavier particles than fly ash (Torrey, 1978).The color of bottom ash ranges from gray to black.
