The aim of this study was to investigate the physicochemical changes during co-composting of chippedground oil palm frond (CG-OPF) and palm oil mill effluent (POME). Results showed that co-composting of CG-OPF and POME was completed within 60 days with average C:N ratio of 23. Temperature of the compost observed in thermophilic phase was at 53.5oC […]
