Comparison of a variety of physico-chemical techniques in the chronological characterization of a compost from municipal wastes

The degree of stability and maturity of the organic matter are fundamental features of the chemical characterization of compost. These characteristics are related to the extensive formation of aromatic structures and of oxygen-containing functional groups. The increase of the amount of these chemica...
