Aerobic composting is considered as an appropriate alternative technology for processing the Slaughterhouse Solid Waste (SSW), for itâ€™s fast performance and ability to retain nitrogen.This research was aimed to characterize the aerobic composting process of the SSW, including nitrogen distribution. A total of 6 reactors of 60 L capacity were used for 50 day aerobic composting period. Raw material compositions were varied in order to represent different C/N ratios. Variations of the raw materials were: (1) 40% paunch manure, 40% grass feed residue, 20% rice straw; (2) 100% paunch manure; and (3) 100% grass feed residue. Aerobic condition was maintained with 0.5 L air supply/kg dry weight solid waste.min. The results showed that the compost product had organic carbon content of 30.51%; total nitrogen of 2.58%; C/N ratio of 11.83, and total phosphorus of 80,18%.
