A1. Preliminary characterization of ash, organic materials and mining soils
DURATION: 1-1-2016 to 30-06-2016
This Action provided a full characterization of materials with potential for use as soil additives, including bottom and fly ash from residual forest biomass combustion, secondary sludge and organic compost materials. Degraded soils in mining areas were also characterized during the course of this action. Analyses performed included pH, moisture content, loss-on-ignition, particle size distribution, bulk density, major and minor chemical elements, dilute salts, mineralogical analysis (X-ray diffraction and optical microscopy), water soluble chemical elements and organic contaminants (e.g. PAHs and PCDDs/Fs), among others. As a result, specific types of ash and organic materials were selected and tested as soil additives in Action A2.
