Bottom Ash

Bottom Ash

Bottom ash is collected at the end of the grate in a Waste-to-Energy plant.

It consists of non-combustible materials, and is the residual part from the incineration of household and similar waste. Raw bottom ash is a granular material that consists of a mix of inert materials such as sand, stone, glass, porcelain, ferrous and non-ferrous metals, and ash from burnt materials
