WASTES

LABORATORY

The Analitica laboratory carries out environmental, mineralogical, and chemical analyses of inorganic solid waste, inert materials, ashes, industrial production residues and materials intended for landfill disposal. Waste analysis can be performed through characterization of crystalline phases by X-ray diffraction (XRD), chemical analysis by X-ray fluorescence (XRF) for the determination of chemical elements, metals, sulfides, oxides, etc. or through thermal characterization by means of static and dynamic heating and evaluation of volatile components (H2O, CO2, organic matter) using thermogravimetric and differential thermal analysis.

Mineralogical, chemical, and particle-size characterization of excavated soils and rocks is carried out in accordance with italian Ministerial Decree DM 161/2012, in order to assess their potential use as by-products or recovery materials. The presence/absence of asbestos in soils, rocks, and demolition waste is verified by X-ray diffraction (XRD) and optical microscopy with polarized light (PLOM).

Analytical and research activities are also conducted on contaminated soils and hazardous/toxic waste, in order to support remediation projects for areas contaminated by industrial materials, asbestos and production residues.
