Abstract(s)The characterization of the organic matter from raw organic wastes, unmatured compost and maturated compost was performed by different techniques: gravimetric, FTIR-ATR, TGA and from the ability of their extracts to bind Cd2+ (evaluating the free cadmium ion by AGNES). Although the amount of humic-like and fulvic-like acids did not change significantly, the structure and properties of the organic matter changed with composting and maturation. These changes resulted in an increase of the stability of the organic material toward thermal decomposition and in an increase of the capacity to bind cadmium.
