도시폐기물의 퇴비화 과정중 퇴비중의 탄소화합물 함량을 시기별로 조사한 결과 다음과 같다. 1. 유기물, 섬유소, 총 탄소, 유기탄소, 미생물 분해가능 탄소 함량은 퇴비화에 따라 감소되었고 리그닌, 미생물 이용 불가능 탄소함량은 약간 증가 되었다. 2. 총 탄소와 미생물 분해가 가능 탄소 함량과 차이는 6.2% 였다. 3. 유기물질의 실제 분해율은 분해율보다 큰 증가 현상을 보였다. 4. 모든 탄소화합물의 실제 분해 능력은 분해능력과 유사하였다. 5. 리그닌의 분해율 및 분해능력은(-)값을 보였으나, 실제 분해율 및 실제분해 능력은(+)값을 가졌다. 6. 퇴비중 유기물, 섬유소, 총탄소, 유기탄소, 미생물 이용 가능 탄소간에 고도의 유의성있는 정의 상관이있었다. 7. 미생물 분해불가능 탄소와 유기물, 섬유소, 총 탄소 유기탄소 및 미생물 분해가능 탄소와는 부의 상관이 있었다. 8. 퇴비중 리그닌과 미생물에 분해 불가능 탄소와도 고도의 정의 상관이 있었다.

To investigate the seasonal changes of various organic and inorganic compounds in compost, carbon compounds in compost were analyzed at various composting periods. Contents of organic matter, cellulose, total carbon, organic carbon and biodegradable carbon in compost were decreased with the progress of composting. In contrast, contents of lignin and nonbiodegradable carbon were increased a little with the progress of composting, but effective contents of lignin were decreased with the lapse of composting time, while effective contents of nonbiodegradable carbon were not changed. Total carbon contents in organic matter in compost were decreased within 9 weeks after composting, and then increased thereafter. Difference between average values of total and biodegradable carbon contents was 6.2%. Actual decay rates of all the carbon compounds were higher than decay rates of the compounds at all the experimental periods. Both of actual decay rate and decay rate of all the carbon compounds were increased rapidly within 2 weeks after composting, and thereafter the rates were increased slightly with the lapse of composting time. Especially the decay rates of cellulose were increased from 9 to 21 weeks after composting. Actual degradation capacity showed the same tendency to degradation capacity of all the carbon compounds in compost. Decay rate and degradation capacity of lignin in compost had minus values, while actual decay rate and actual degradation capacity had plus values. Highly positive correlations were observed among organic matter, cellulose, total carbon and biodegradable carbon one another. Nonbiodegradable carbon showed highly negative correlation with organic matter, cellulose, total carbon, organic carbon and biodegradable carbon, respectively. The same tendencies were observed between lignin and organic matter, cellulose, total carbon, organic carbon and biodegradable carbon. Highly positive correlation was observed between lignin and nonbiodegradable carbon in compost.
