Abstract
The significance of the organic matter evolution index (OMEI) related to the composting process degree was tested on a full-scale windrow pr ocess for 239 days. Analytical data from many samples collected during the process and kinetics were in agreement regarding the insufficient degree of stability and maturity reached by the compost obtained. As expected, the OMEI at the end of the process was low (OMEI = 0.46) con firming its validity to composting degree evaluation. New analytical m ethods for humic substances quantification were developed by monitorin g humic acids concentration versus composting time and Ligno-humic fra ction.
