• Aerobic composting
• Compost materials
• Different treatments
• Environmental temperature
• Lentinus edodes
• Lignin structure
• Maximum temperature
• Pleurotus ostreatus

In this study, we used Lentinus edodes residues (XG) and Pleurotus ostreatus residues (PG) as compost materials and used a high-temperature static aerobic composting system to examine the effects of different treatment. We analyzed changes in temperature and compost structure during the process of composting. The study showed that XG and PG mixed by 1:1 increased the temperature of the compost pile and reached to the environmental temperature more rapidly. Mix treatment had maximum temperature of 71°C, had longest megathermal period continued about 9 days than other groups. Scanning Electron Microscope (SEM) showed mix treatment had the best lignin structure variation trend while PG had the worst. Thus, mix treatment significantly increased the composting rate, reaching complete decomposition 10 days before other treatments. These data also suggested that XG as a compost material is better that PG.
