Bottom Ash - an overview ScienceDirect Topics

5.4 Processing of NF Metals From Incinerated Bottom Ash. In a waste incineration plant, different by-products are produced. Volume and mass of the processed waste are reduced by the incineration process. The largest amount of residual material is bottom ash and up to 15–30 mass% or 10–20 vol.% remain as bottom ash. There are two different ...
