This study was carried out to investigate how to reuse the livestock waste and develop fly ash as a subsitution of sawdust which is used commonly to make compost. Fly ash and sawdust were mixed the ratio of 8 to 2, 7 to 3, 6, to 4, 5 to 5, 4 to 6. 3 to 7 and 2 to 8 after fermentation for 60 days the change of temperature, moisture, pH, organic matter, nitrogen content and C/N ratio were analyzed. The results are as follows; Temperature was reached to maximum (63.5$^{\circ}C$) more quickly in scraper type than in slurry type with adding large sawdust. When fly ash and sawdust were mixed same amount at scraper type and slurry type, moisture was 46.6~53.7% and maintained a good condition for fermentation. pH was showed the range of 7~10 as a mixture of fly ash. Organic matter contents were increased with increasing the added sawdust but did not show any tendency. Nitrogen content was also increased with increasing the amount of added sawdust but did not show any tendency. C/N ratio was increased to 20~60 with increasing the added sawdust, but when sawdust and fly ash were mixed 50:50, there was no significant during fermentation periods. In conclusion, supplementation of fly ash at the level of 50% of sawdust maintained a good condition for fermentation as a livestock waste composting.
