Characterisation of humic acid maturation by fluorescence spectroscopy and thermal analysis during composting of olive mill waste
Humic acids isolated from different stages of olive mill waste composting were investigated by Elemental analysis, Fluorescence spectroscopy and by Differential Scanning Calorimetry (DSC). The Elemental composition of these humic acids indicates an increase in aromatic structures during the composting. Indeed, the fluorescence results showed an increase in condensed aromatic ring systems. ...

Composting
Introduction Composting is a controlled biological process by which organic contaminants (e.g., PAHs) are converted by microorganisms (under aerobic and anaerobic conditions) to innocuous, stabilized byproducts. Typically, thermophilic conditions (54 to 65 °C) must be maintained to properly compost soil contaminated with hazardous organic contaminants. The increased temperatures result from heat ...
