摘要

This study compares the composting performance of organic waste commonly generated in Morocco using Rotary Drum Composting (RDC) and Static Composting Container (SCC) systems. Composting efficiency was evaluated under controlled conditions through physicochemical and microbiological monitoring. RDC showed rapid thermophilic development, accelerated organic matter degradation, and faster C: N ratio reduction, achieving compost maturity within 19 days, whereas SCC required 90 days and exhibited slower stabilization with higher moisture retention. Microbiological analyses demonstrated clear microbial succession and effective reduction of indicator microorganisms in both systems, confirming hygienic stabilization. Both composting systems produced stable and microbiologically safe compost, highlighting the importance of system selection based on operational objectives and environmental conditions for sustainable organic waste management in Morocco.
