Abstract:
The aim of this study was to evaluate xenobiotics contents (Detergent, heavy metal and chloride) of final compost made from different wastes (Textile sludge, municipal sludge, municipal waste and garden waste). After composting, there was an increase in total heavy metal contents in compost because of loss of mass due to biodegradation of organic matter. In addition, we recorded a slight increase of chloride content. On the other hand, this study demonstrates that aerobic biodegradation has important environmental consequence for detergent contents in the pile that biodegrade in the presence of air during the composting process. However, proper consideration should be given to the compost metal content and further field studies are required to examine the long-term effect of the final product in soils, particularly in relation to biological indicators of soil quality.
