Chemical transformations of organic matter during the composting of wood industry wastes residues. Cristiane R. Budziak; Claudia M. Maia; Antonio S. 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.
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.
Keywords: humic acid structures; composting of sawdust; paper mill sludge. As madeiras moles, ou gimnospermas, possuem ligninas formadas fundamentalmente de unidades G. Filley et al. Amostras do material foram tomadas nos seguintes tempos de compostagem: 0 A0 , 2 A1 , 8 A2 , 15 A3 , 22 A4 e 29 dias A5. Verifica-se que, em geral, o teor de MO diminui com o tempo de compostagem, sugerindo a perda de CO 2 e CH 4 durante o processo.
