CHEMICAL TRANSFORMATIONS OF ORGANIC MATTER DURING THE COMPOSTING OF WOOD INDUSTRY WASTES (RESIDUES). Composting of sawdust and paper mill sludge, using a “Kneer” process reactor, was studied in an attempt to elaborate upon organic matter (OM) transformation during the process and to define parameters to measure the compost maturity level. Temperature, electron paramagnetic resonance (EPR) data, ash and C, H, N and S contents, and a spectroscopic method using ultraviolet-visible (UV-VIS) for alkaline (pH = 8.5) and solid samples was used to study the maturity of the compost samples. These parameters were measured in 6 humic acids (HA) extracted from the compost samples during 29 days. The results of this work show that the “Kneer” process is efficient in transforming ligno-celulitic residues in a short time (29 days), into an organic fertilizer material with application perspectives. |
