The activated sludge from the wastewater treatment plant (WWTP) of Tipaza, rich in plant sawdust, and chicken manure from the company Avicola, rich in nitrogenous matter, appears to be perfectly compatible for co-composting. The compost of these two biomasses gives a satisfactory result confirmed by the monitoring of the C/N ratio, a key indicator of the state of composts. Furthermore, the physicochemical parameters and spectral methods are in favor of the development of  spreadable compost.


Key words: Wastewater treatment, activated sludge, composting, chicken manure, revaluation, aerobic process.
