Chemical composition and condition of acid hydrolysis of waste composts during the cultivation of oyster mushroom (Pleurotus ostreatus) were determined. Ash content of composts increased while organic matter content decreased as the cultivation progressed. More than 90% of mushroom was produced from the first and second cropping period. An optimum condition for acid hydrolysis was at 2.0% $H_{2}SO_{4},\;1.5kg/cm^{2}$ vapor pressure for 30min and 20times (acid/compost). Formation of furfural in acid hydrolysis increased remarkably as acid concentration increased.
