# Laboratory bottom ash analysis

## Would you like to have a laboratory bottom ash analysis carried out?

### What is bottom ash?

Bottom ash is a solid residue resulting from the combustion of materials, and it is made up of incombustible materials (e.g. glass, metals, silica, alumina, limestone, lime and unburned residues…).

There are two types of bottom ash:

  the first is the residue from the incineration of coal or coke in industrial furnaces the second comes from the incineration of household waste in Non-Hazardous Waste Incineration Units (UIDND)
Bottom ash can contain halogens such as chlorine and fluorine. Bottom ash analysis for [halogens](https://filab.fr/en/our-services/our-analysis-services/halogen-analysis-laboratory.md) is essential to assess the potential for environmental pollution and to ensure that the residues do not release toxic substances into the soil or groundwater. This analysis also helps determine the appropriate treatment processes for bottom ash before its use or disposal in landfill.

### What are the advantages of this material?

Bottom ash has a number of advantages, notably its abundance and excellent geotechnical properties.

As a result, it is used in solid concrete blocks of all sizes, load-bearing bottom-ash concrete walls, and also in road construction.

### Why carry out a bottom ash analysis?

Bottom ash from waste treatment is more or less polluted and must be recycled with care. Due to their nature, bottom ash may have a high dioxin content and contain many pollutants such as heavy metals or hydrocarbons.

To protect the environment and avoid any risk, legislation requires leaching tests on many substances. Thus, the following elements As, Ba, Cd, Total Cr, Cu, Hg, Mo, Ni, Pb, Sb, Se, Zn, Fluorides, Chlorides, Sulfates must be analyzed. It also specifies conditions of use outside flood-prone areas, near watercourses and drinking water abstraction points…
