In this research, a hot composting experiment was carried out with a mixture of three waste fractions; guts 50%, manure 30% and dead leaves 20%. The experiment showed that the resulting compost has a high-level organic substance content and a minor salt content that can be a healthy soil amendment. However, the experiment did not evaluate the compost mass evolution during 45 days of the mechanism. The main aim of this work tried to improve the performance of valorization by reducing the duration of composting, evaluating its economic efficiency (monitoring of mass), and improving the qualitative efficiency. To this effect, the feasibility study aimed to rapidly compost a mixture of 50% underground guts waste and 50% manure over a period of 23 days. The results proved that the C/N rate and electrical conductivity of the compost obtained is above the limits requested by most standards. Moreover, the temperature recorded of the heap did not exceeded 39.53°C at any day of composting. Nevertheless, the economic efficiency reached 47.9%.
